Premise
Lima is an easy place to melt glass and a hard place to sell it. The city has cheap piped natural gas, a mining economy that digs up every oxide in a glass batch, an industrial glass sector already melting soda-lime at scale, and eleven million people with a documented appetite for design. Nothing has to be invented. The questions are grade, price, and who buys.
This is a theoretical study. It builds a specific hot shop in a specific city and asks what the place gives, what it withholds, and what the business has to look like to survive there. Lima is a useful place to do that because it isolates the half of the problem most working studios actually face: the inputs are cheap, so the constraint moves to demand, import friction, and the distance between a workshop and a buyer with money.
The studio is a reference hot shop: one 500 lb furnace, two glory holes, two annealers, a cold shop, room for six to eight people. Figures are in US dollars at 2026 prices, with sources where they exist and marked approximate where they do not.
The ground
Peru can supply four of the five things a hot shop eats from inside its own borders: silica, lime, alumina-bearing feldspar, and fuel. Only soda ash is imported, and the container-glass industry in Callao imports it by the shipload already, so a studio buys it off a local distributor rather than a foreign one.
The industry that is already here. Peru melts about 406,000 tonnes of container glass a year, with Lima and Callao holding 72% of furnace capacity: Owens-Illinois runs plants at Bellavista and Lurín, and Heinz-Glas, Cristalerías Ferrand and smaller producers sit nearby. That matters more than any quarry. It means there are refractory suppliers, furnace technicians, batch distributors, and a cullet stream within an hour's drive. A Lima studio is not a pioneer; it is a small customer in a mature supply chain.
| Batch need | Peruvian source | Grade and catch |
|---|---|---|
| Silica (SiO₂) | Peru exports silica and quartz sand under HS 250510; deposits on the coast south of Lima and in the north | Domestic sand is used for cement and foundry work. O-I still imports glass-grade sand for low iron. A studio melting clear crystal buys imported sand through the same Callao importers; a studio happy with a pale green tint can use local |
| Soda ash (Na₂CO₃) | None mined. Imported in bulk to Callao for the bottle plants | The one true import. Available locally by the pallet at a distributor's margin |
| Lime (CaO) | Everywhere. UNACEM quarries limestone at Atocongo inside Lima's city limits for cement | Glass-grade limestone and dolomite are trivial to source |
| Feldspar / alumina | A Peruvian albite ore tested at about 90% feldspar, 22–24% Al₂O₃, under 0.6% Fe₂O₃ after beneficiation | Usable for glass after processing; also supplied to Peru's ceramics industry |
| Borates | Southern Peru holds ulexite deposits at Laguna Salinas, Arequipa, worked by Ulexandes and others | Peru is a borate producer. Relevant for borosilicate and for some color chemistry, not for a soda-lime hot shop |
| Cullet | Weak collection outside Lima, but O-I's supermarket return program and start-ups feed Lima's furnaces | Container cullet is green or amber and the wrong recipe for a studio furnace. Useful for casting and color-neutral sculpture, not for clear blown work |
| Fuel | Camisea natural gas, piped through Lima and Callao by Cálidda | Lima pays the lowest gas tariff in the country; regional industrial users pay roughly 1.8 to 2.6 times Lima's rate. A Lima household pays about half what it would for bottled LPG |
| Electricity | National grid, hydro and gas | About $0.18 per kWh for business as of mid-2025, near the world average. Not cheap enough to favor an electric furnace over gas |
| Refractories | Suppliers to the bottle plants and the mining smelters | Castables, bricks, and fiber are stocked locally. Furnace pots and invested crucibles still come from the US or Europe |
| Water, air, climate | Coastal desert: 18°C average, almost no rain, high humidity | Mild year-round. No heating load, no snow load, no cooling load worth the name. Humidity and salt air are hard on steel and electronics |
The practical reading: the land gives nearly the whole batch and the cheapest furnace fuel on the continent, and gives it in a city that already runs eight glass furnaces around the clock. What Peru does not give is finished studio equipment, color bar, or the quartz-pure sand for lead-free crystal. Those arrive in a container at Callao, the same way they would arrive anywhere outside the handful of countries that make them.
Local versus imported
About 60% of the studio by cost is local; about 60% by weight is local too. The imported 40% is the furnace, the glory holes, the annealers, the pots, the color, and the hand tools. The building, the gas, the batch, the refractory lining, the benches, the labor and the steel all come from within Lima.
Two trade facts shape the manifest. First, the US–Peru Trade Promotion Agreement has put US-origin industrial goods at zero duty since 2009, so a furnace built in Oregon or North Carolina clears Callao paying only Peru's 18% IGV, which a registered business recovers as input tax. Second, Peru's general tariff on most capital goods is 0% regardless of origin, so a Czech or German furnace pays the same. The friction is not duty; it is freight, a customs broker, and four to six weeks on the water.
| Item | Source | Approx. cost delivered ($) | Note |
|---|---|---|---|
| Gas furnace, 500 lb, recuperated, with controls | Imported, US or EU | 55,000 | Gas, not electric: Lima gas is cheap and the grid is not. Freight and broker add about 12% |
| Two gas glory holes | Imported | 16,000 | Could be built locally by a boilermaker from an imported burner set; first unit imported for reference |
| Two annealers | Imported, or built locally | 12,000 | Lima has kiln builders serving the ceramics trade; electric annealers are an easy local build with imported elements and controllers |
| Furnace pot and spare | Imported | 6,000 | No local source for invested or fused-silica pots |
| Refractory castable, brick, fiber | Local | 9,000 | Stocked for the bottle plants and smelters |
| Pipes, punties, jacks, shears, blocks | Imported, US or Italy | 14,000 | Peru has steelworkers but not glass-tool makers; a local shop can turn punties once it has a pattern |
| Benches, marvers, yokes, pipe cooler, racks | Local | 7,000 | Lima metal fabrication at roughly a third of US shop rates |
| Cold shop: lathe, flat wheel, belt sander, saw | Imported, except the frames | 22,000 | Diamond wheels and lathes imported; tables and plumbing local |
| Batch: sand, soda ash, lime, feldspar, 10,000 lb/yr glass | Local distributor (soda ash and low-iron sand are themselves imported) | 4,000 | Bought through Callao batch suppliers who serve O-I and Ferrand |
| Color bar and frit | Imported, Germany or New Zealand | 8,000 | No substitute |
| Building shell, 3,000 sq ft industrial lease or build | Local | see cost section | Lima industrial space is plentiful south and east of the center |
| Gas service, 2-inch line and regulator | Local (Cálidda) | 6,000 | Connection cost varies by district and distance to main |
| Electrical, 3-phase, exhaust hood and fans | Local | 18,000 | |
| People: two gaffers, two assistants, one technician, one manager | Local, with one foreign lead gaffer for the first two seasons | wages in opex | Peru has lampworkers and ceramicists but almost no furnace-trained glassblowers; the first hires are trained on site |
| Freight: two 20-foot containers, US Gulf to Callao, plus broker | — | 11,000 | Four to six weeks door to door |
Total imported equipment lands at roughly $145,000 including freight and broker; local goods and services for the fit-out run about $50,000 before the building. The ratio is the point. In most of the world a new hot shop crosses an ocean almost in its entirety; in Lima the ocean carries only the things nobody in South America makes. If one of the studio's business lines is building and selling studio equipment into Latin America, the list of imports is also a list of what that business would make.
The build
The hot shop goes in Chorrillos or the Lurín industrial corridor; the showroom goes in Barranco or San Isidro. Trying to put both in one building forces a choice between zoning that allows a 2,100°F furnace and foot traffic that buys a $2,000 lamp, and in Lima those two are 10 to 30 kilometers apart.
Site options
| District | Distance from Miraflores | Industrial rent, approx. | For | Against |
|---|---|---|---|---|
| Barranco | 3 km | Residential and commercial lots only; $12–20/m²/month | The arts district: galleries, boutique hotels, MATE museum, the densest tourist and design foot traffic in the city | Zoning will not permit an industrial furnace; small lots; neighbors. Right for the showroom, wrong for the furnace |
| Chorrillos | 8 km | $5–8/m²/month | Mixed light-industrial zoning, 15 minutes from Barranco, on the Costa Verde; gas main present | Patchy infrastructure; some streets unpaved; security varies block to block |
| Villa El Salvador industrial park | 20 km | $4–6/m²/month | Lima's furniture and metalworking cluster: the fabricators, welders and kiln builders are neighbors | Far from any buyer; no tourism; purely a production address |
| Lurín | 35 km | $4–6/m²/month | Purpose-built industrial parks, O-I's bottle plant and its refractory suppliers next door, Pachacamac ruins and the valley's weekend restaurants nearby | 45–75 minutes from the center; staff commute; tourists need a reason to come |
| Callao / Ventanilla | 15 km | $5–7/m²/month | Port adjacency: imports clear and arrive the same day; the batch distributors are here | No visitors, heavy traffic, industrial grit |
The recommendation is Chorrillos: a 3,000 sq ft warehouse with a 20-foot clear height, close enough to Barranco that a hotel can send guests in a taxi, far enough into light-industrial zoning that a furnace is a routine permit.
Energy. A recuperated gas furnace at 500 lb idles near 350,000 BTU/h. On Lima's industrial gas tariff that is roughly $14,000 to $20,000 a year, labeled approximate because Cálidda publishes tariffs by consumption band and the studio sits at the bottom of the industrial range. The same furnace on electricity at $0.18/kWh would cost about $19,000 a year in energy alone and expose the studio to Lima's voltage sags; gas wins on both counts. Glory holes and annealers follow the same logic: gas for the glory holes, electric for the annealers because they need control more than heat.
Climate. Lima's 18°C average and near-zero rainfall remove the heating and cooling loads that dominate a North American hot shop. The building needs shade, a large exhaust path, and cross-ventilation; it does not need insulation. Salt humidity off the Pacific corrodes mild steel and corrupts electronics, so controllers go in sealed enclosures and benches get painted twice.
Seismic. Lima is one of the most seismically exposed capitals in the world. The furnace, glory holes and annealers are anchored to the slab; the gas line gets a seismic shut-off valve; pot and crucible stock are stored low. This is not optional and it is not expensive.
Permits and timeline. Nine to twelve months from lease to first gather, most of it waiting.
- Months 1–2: company formation or branch registration, RUC with SUNAT, lease signed, equipment ordered
- Months 2–4: municipal operating license, Defensa Civil safety inspection (ITSE) for a high-risk establishment, Cálidda service application
- Months 3–5: building fit-out by local contractors; electrical, exhaust, gas service, slab anchors
- Months 4–6: equipment on the water, through Callao customs, delivered and set; local builds of benches, annealers and racks in parallel
- Months 6–7: commissioning, first melt, staff training with the lead gaffer
- Months 7–12: soft production; showroom lease and fit-out in Barranco or San Isidro
The furnace runs year-round. There is no season to shut down for, so the numbers in the next section are per year.
Cost analysis
About $380,000 to build including a Barranco showroom, about $315,000 a year to run, and roughly $60 per bench-hour all-in. The same studio in upstate New York costs about the same to build but $550,000 to $650,000 a year to run, mostly wages, rent and winter fuel. Lima is at parity on capital and roughly half on operations.
All figures are approximate planning numbers in 2026 US dollars. Equipment prices are current studio-builder quotes; Lima rents, wages and utilities are drawn from the sources above and from published Lima market ranges, and should be re-quoted before any real budget.

Operating cost per year
| Line item | Lima ($) | Note |
|---|---|---|
| Five local staff: two trainee gaffers, two assistants, one manager | 105,000 | Skilled-trade wages in Lima run $800–1,400 a month; Peruvian law adds two extra months' pay, bonuses and health cover, about 35% on top |
| Foreign lead gaffer | 60,000 | Two-year contract while the local team trains |
| Natural gas, furnace and glory holes | 17,000 | Lima industrial tariff; the cheapest in Peru |
| Electricity, annealers, cold shop, lights | 8,000 | At about $0.18/kWh |
| Batch, 25,000 lb of glass | 4,000 | Year-round melt |
| Color bar and frit | 8,000 | |
| Pots, elements, refractory | 10,000 | |
| Hot-shop rent | 24,000 | |
| Showroom rent, Barranco | 24,000 | |
| Maintenance, insurance, accounting | 24,000 | |
| Marketing, fairs, photography | 15,000 | Casacor participation alone can be $10,000–30,000 |
| Packing and shipping finished work | 10,000 | Crating for export is the hidden cost of selling abroad |
| Opex subtotal | 309,000 | |
| Capital amortized over 10 years | 38,000 | |
| All-in per year | ≈ 347,000 |
Unit economics. Two benches, six days a week, ten hours a day, 48 weeks a year gives 5,760 bench-hours and about 25,000 lb of glass worked. That is $60 per bench-hour and $14 per pound all-in, against roughly $100 to $120 per bench-hour for a comparable US studio once its real overhead is counted rather than its subsidized rental rate.
The lever here is not energy. Gas is 5% of the budget. Wages are 53%, and the wage line is the one that moves: once the local gaffers are trained and the foreign lead goes home, opex drops by $60,000 and the bench-hour falls under $50. The second lever is the showroom, which is 18% of opex and produces nothing unless the business models in the next section turn it into revenue.
Business models
Four models each clear a meaningful share of the $347,000 a year on their own, and three of them reinforce each other: hospitality and architectural commissions, a teaching program, export to the United States under a zero-tariff treaty, and tourist demonstrations. The studio that survives runs the first three and uses the fourth to fill the quiet hours.
| Model | Revenue per year ($) | What it takes | Verdict |
|---|---|---|---|
| Hospitality and restaurant commissions | 150,000–400,000 | Relationships with Lima's restaurant groups, boutique hotels and the developers behind them; a lighting line and a tableware line | Lima is the gastronomic capital of South America and its top restaurants already commission ceramics from local makers. Nobody is offering them blown glass made in the city. Custom pendants, decanters and bar glass are the natural first contracts |
| Architectural and residential lighting | 100,000–300,000 | A catalogue, a Casacor presence, interior-designer relationships | The interior design market is growing on the back of real-estate development; buyers furnish at about 10% of property price and design projects at several times that. Everything in the market today is imported, and imported lighting pays freight, duty and a dealer margin that a local maker does not |
| Teaching: classes, workshops, a residency | 80,000–200,000 | A third bench, a teaching gaffer, housing partners | Peru has no furnace-glass program. There are lampworkers in Lima and Cusco and ceramicists everywhere, and there is nowhere on the continent south of Mexico to learn to blow glass at a furnace. A residency draws from Chile, Colombia, Argentina and Brazil; weekend classes draw from Lima's professional class and from tourists who stay a week |
| Export to the United States | 100,000–300,000 | A US distributor or the maker's own US brand; FTA certificates of origin; good crating | Peruvian-origin goods enter the US duty-free under the trade promotion agreement, and Lima-to-Miami air freight runs daily. A $14-a-pound cost base selling into a market that pays $150–600 for a handmade pendant is the widest margin in this study |
| Regional wholesale: Chile, Colombia, Mexico | 50,000–150,000 | A Pacific Alliance origin certificate; reps in Santiago and Bogotá | Zero tariffs inside the Pacific Alliance; Santiago is the richest design market on the west coast and two hours by air. Chile alone sends 1.28 million visitors to Peru a year |
| Tourist demonstrations and guest-made objects | 60,000–150,000 | A viewing gallery, a hotel-concierge program, two afternoon slots a day | Peru took 4.16 million international visitors in 2025, most of them through Lima for a night or two on the way to Cusco. A $60 demonstration and a $150 blow-your-own paperweight are modest against a $4,000 trip. The ceiling is attention, not price: Lima competes with Barranco's galleries and a 7 pm reservation at Central |
| Corporate awards and mining gifts | 30,000–80,000 | A trophy line, a sales call to the mining chambers | Peru's mining and banking sectors buy thousands of awards and gifts a year, almost all imported crystal. Low glamour, steady cash |
| Studio equipment for Latin America | 40,000–120,000 | A boilermaker partner and the import manifest above as a product list | Every glory hole, annealer and bench a Lima studio builds for itself is a product no one else on the continent makes. Sold to the next studio in Bogotá or Santiago at half the landed cost of a US unit |
| Production glassware line | 50,000–150,000 | Molds, a repeatable form, a retail partner | A 500 lb furnace caps volume. Tumblers and carafes for Lima's design shops are good training for the apprentices and good filler between commissions, not a business on their own |
The stack that works. Hospitality and architectural commissions, a teaching program, and US export yield roughly $450,000 to $1.1 million gross against $347,000 all-in. That is a real business at the low end and a well-capitalized one at the high end. Tourism, awards and regional wholesale each add $50,000 to $150,000 without new fixed cost.
What the local economy gets. Six skilled jobs at wages above the Lima median, a trade that did not exist in the country, a supply contract for a local metal shop, and a product category Peru currently imports in full. If the teaching program takes root, Lima becomes the place South Americans learn furnace glass, the way Penland or Pilchuck anchor their regions. That is the version of this studio that would matter in twenty years, and it costs no more than the others to start.
High-end design and the showroom
The showroom goes in Barranco, on the gallery blocks within a short walk of the Puente de los Suspiros, and it is built as a gallery, not a shop. The trade is reached through Casacor once a year and through San Isidro's design corridor by appointment. The money outside Peru is reached in two steps: Santiago first, Miami second, and only then New York.
Who buys in Lima. Three groups, and they are in three different districts.
| Clientele | Where they are | How to reach them |
|---|---|---|
| Interior designers and architects specifying for residential and hospitality projects | San Isidro: the financial district and the design corridor around Avenida Conquistadores and Camino Real, where the imported furniture and lighting dealers cluster | A trade account, a specification binder, and a Casacor space. Designers in Lima buy from showrooms they can bring a client to; appointments at the hot shop in Chorrillos work better than a second storefront |
| Private collectors and the design-literate public | Barranco: the galleries, MATE, the boutique hotels, the Saturday crowd | The showroom itself. Barranco is the only district in Lima where someone wanders in off the street and spends $3,000 on an object |
| Developers, hotel groups and restaurant groups | Wherever their next project is; decisions made in San Isidro and Miraflores offices | Direct sales, a lighting catalogue, and one visible installation. A single commission in a restaurant on the World's 50 Best list is worth more than any advertising |
The calendar. Casacor Perú ran May to July 2026 at the Jockey Club with 40 spaces across 11,000 m², and most of what is shown is for sale; it is the one event where every designer, developer and design journalist in the country walks past the work. A space is expensive and a glass-lit space is memorable. Lima Design Week, in its tenth edition, and the April art fairs in Barranco round out the year.
Beyond Lima, in order.
- Santiago, Chile. Two hours by air, the richest design market on the Pacific coast, zero tariff inside the Pacific Alliance, and a design trade concentrated along Alonso de Córdova in Vitacura. A rep with a sample set, then a shared showroom. This is the first foreign market because it is the easiest and the nearest.
- Bogotá and Mexico City. Also Pacific Alliance; also zero tariff. Mexico City has the strongest collectible-design scene in Latin America, with Design Week Mexico and the galleries of Polanco and Roma. Bogotá's design trade is smaller but underserved.
- São Paulo. The largest design market on the continent, with DW! São Paulo Design Weekend and the showrooms of Jardins. Harder: Mercosur tariffs apply, Portuguese, and a long trucking leg. Worth it only after the Pacific Alliance markets are working.
- Miami. The hinge between South America and the United States. Peruvian goods enter duty-free, daily Lima–Miami freight is cheap, and the Design District plus Design Miami in December put the work in front of the US trade and the Latin American collectors who keep apartments there. A Miami stockist or a shared showroom in the Design District is the right first US address.
- New York. The largest prize and the slowest. The trade showroom buildings offer visibility to every specifier in the country but sell nothing on their own; a line in a multi-line showroom there is a passive asset unless a rep works it. The better New York entry for sculptural glass is a collectible-design gallery or ICFF in May, with a showroom only once there is a rep to staff it.
The showroom brief. Eighty square meters in a Barranco casona or a converted ground floor on the gallery blocks; high ceilings and controllable light, because lighting is the product; a single long table for tableware and three suspended installations; no cash desk visible. Open Thursday to Sunday, by appointment otherwise. Staffed by the manager, with a tablet that books hot-shop visits and demonstrations. It costs $24,000 a year in rent and $40,000 to fit out, and it is the only line in the budget whose job is to make the studio look like it belongs in the catalogue of a Milan lighting house. If it does that, every other model in the previous section gets easier.
Verdict
A glass studio in Lima is buildable for about $380,000, operable for about $350,000 a year, and viable on commissions, teaching and export without ever depending on tourists. It is a cheap serious hot shop to run, and it has an unusually clear unmet market: a city of eleven million, a continent-leading restaurant scene and a growing design trade, all currently buying their glass from somewhere else.
The shape of the problem is worth naming, because it is the shape most working studios are in. Energy and shelter are 15% of the budget. The market is the constraint that has to be built: a showroom, a trade network, a teaching program, an export channel. Lima is a sales problem with a furnace attached.
Three things to take away:
- Where the batch comes from barely matters. Peru mines most of a glass recipe and the studio still buys its sand through an importer, because grade beats geography. The land's real gifts are cheap gas, a mild climate and a supply chain built for someone else's furnaces.
- Wages are the lever in a cheap-energy economy. More than half the Lima budget is people. The studio's path to profit runs through training, not through the gas bill. That is likely the truth for most studios in most places.
- The showroom is a production asset. Eighteen percent of opex buys nothing a furnace can make, and it is the line that decides whether the glass sells for $14 a pound or $300 a piece. A hot shop without a room where the work looks expensive is a factory; with one, it is a brand.
The one thing a second studio could not copy is the opening itself. Lima's opening exists because nobody has taken it. A second studio changes the arithmetic for both, and the first one's advantage is not its furnace but the two years it spends training the only furnace glassblowers in the country.
