A home glass studio is possible, and it is more constrained by the building than by the budget. Power supply, floor loading, ceiling height and ventilation usually decide the question before cost does.
Start with the building, not the equipment
Before pricing a furnace, answer four questions about the space. If any of them is a firm no, the project stops there and no amount of budget fixes it.
| Constraint | What it needs | Why it stops you |
|---|---|---|
| Power | 380 V three phase for most furnaces | A domestic single-phase supply cannot carry a melting furnace |
| Floor | Solid concrete, no suspended timber | A furnace plus crucible plus glass is a heavy point load |
| Height | At least 2.4 m for a hood and duct | Insufficient height means no workable extraction |
| Ventilation | A route to outside for a 150 - 200 mm duct | An internal room with no duct route is unusable |
Carbon monoxide has no smell. Extraction must go to open air, and a CO alarm in the room is mandatory, not advisory.
Space planning
The working triangle in a hot shop is furnace, glory hole and bench. Everything else is arranged around those three points. The bench should be close enough to reach the furnace without carrying a hot gather across a room, and far enough that radiant heat does not make it unbearable to stand at.
- Furnace and glory hole on the same wall, with a shared hood if possible.
- Bench within one or two steps, with the marver and tool rack immediately to hand.
- Annealing kiln out of the traffic path but close enough to load a hot piece safely.
- Clear floor between all stations. A hot offcut on a cluttered floor is a burn waiting to happen.
- Colour bench away from the furnace so frit dust does not drift into the melt.
Power and services
Most small melting furnaces draw between 12 and 45 kW and expect a three-phase supply. A domestic supply will not run one, and installing three phase is a significant cost that must be quoted before anything else is purchased. Add the annealing oven, lighting, extraction and coldworking machines on top.
| Service | Typical requirement | Notes |
|---|---|---|
| Furnace supply | 380 V three phase, 12 - 45 kW | Dedicated circuit, not shared |
| Annealing oven | 230 V single phase or 380 V | Can often share a sub-panel |
| Extraction | 600 - 1200 m³/h fan | Needs make-up air inlet |
| Water | Cold supply and settling tank | Required for coldworking |
Budget, in the right order
Ventilation and services first
This is the part that cannot be deferred and the part that most people underestimate.
Annealing capacity second
You can gather and blow on borrowed equipment, but a piece that is not annealed is scrap.
Furnace and crucible third
The largest single purchase. Buy the crucible life you can actually maintain.
Hand tools last
Good jacks and shears matter, but they are replaceable and cheap relative to the rest.
Coldworking when you need it
Many studios outsource coldworking for years before buying a wheel.
The alternative worth considering
Renting time in a shared studio costs a fraction of a home setup and gives you better equipment, other people to learn from, and someone to notice when you are about to do something dangerous. For most people, for the first several years, it is the better answer. Build the home studio when you know exactly what you want in it.
Spend a year renting studio time and keep a list of what you actually reach for. That list is your shopping list, and it will be shorter and cheaper than you expect.
A home studio is a building project that happens to involve glass. Approach it in that order and the glass part becomes the easy part.
This article is educational reference material. Hot glass work involves severe burn, fume and fire hazards. Wear eye protection, heat-resistant gloves and natural-fibre clothing, ventilate every heat source to open air, fit a carbon monoxide alarm, and take hands-on instruction before operating any hot glass equipment.
No guarantee of results. Techniques, temperatures and schedules described here are reference guidance based on common studio practice. Glass behaviour depends on your materials, equipment and technique. Test everything on your own setup and follow the manufacturer's instructions.
