Part of Independent ceramic studios companies: a way to assess work
Independent ceramic studios storage guide for home potters
Independent ceramic studios storage guide: separate dry powders, wet materials and finished work, label containers, and organize shelves by use.
Independent ceramic studios storage plans can start simply: sort materials by hazard rather than convenience, and write the rules down. Copying that is the cheapest improvement a home potter can make, because it costs shelving and a marker.
What to take away
- Store by hazarddry powders, wet materials and finished work each get their own place.
- Dry material is measured and mixed in a designated area with local exhaust, not on the workbench.
- Every secondary container gets the material's full name on it.
- Know your disposal route before you buy anything containing a toxic metal.
Separate the dry from everything else
A university art safety guide sets out the hazards by process and the precautions that follow. Its ceramics section notes that clay contains crystalline silica which can cause silicosis and may be a human carcinogen.
Handling or mixing clay in powder form is an inhalation hazard, and some clay additives such as talc may be contaminated with asbestos. Its control is a designated area where materials are measured and mixed, with snorkels positioned directly above the work area for local exhaust.
It also flags what most home potters underestimate: physical strain from wedging, throwing and hand building, wrist and back injuries from long sessions at the wheel, and the need for functioning ventilation for all firing processes.
The home translation is blunt. If you cannot capture dust at the point of mixing, buy premixed wet clay and prepared glazes and do not keep dry powders at all.
Label everything, in the same way, every time
The same guide notes that when chemicals are moved from a manufacturer's container into a secondary container, that container must be labeled with the material's complete name. A yogurt tub of gray powder is not storage; it is a future disposal problem.
Label everything
| Container | Label must show |
|---|---|
| Bagged clay | Body name and cone |
| Reclaim bucket | Body name, and the date it was started |
| Mixed glaze | Glaze name, cone, and mix date |
| Dry material | Full material name, and the safety data sheet on file |
| Test tiles | Body, glaze, cone, dip time |
Know the disposal route first
Glaze materials with metal content do not go down a drain or into household trash. A county hazardous waste program's advice to hobbyists names the ceramics hazards directly, silica dust from dry clay, asbestos in clay slip, glazes and stains, along with toxic metals including cadmium, chromium, cobalt and lead.
It advises keeping containers, solvents and thinners covered when not in use. Wear chemical-resistant gloves with solvents, and nitrile gloves for throwing if you react to nickel or copper. Wear goggles that block infrared when firing. Take materials containing lead, cadmium or barium to a household hazardous waste drop-off.
The U.S. Environmental Protection Agency (EPA) administers the Resource Conservation and Recovery Act (RCRA); household hazardous-waste drop-off options are handled through state and local programs, so confirm what your local site accepts. Find your local drop-off before you buy anything on that list. It takes ten minutes and it settles what you are willing to keep in the house. It also sets the boundary for how you present and sell work, and for what equipment is worth owning at all.
A shelf plan that works at home
- Top shelfsealed dry materials, labeled and dated, nothing heavy.
- Middlebagged clay in lidded bins, off the floor and easy to lift.
- Bench heightmixed glaze in lidded buckets with fired test tiles attached.
- Floor levelreclaim, lidded, next to the wheel.
- Separate rackgreenware and finished work, with dust covers.
Common questions
Can I keep dry glaze materials in a garage?
Only sealed, labeled, off the floor and away from anything that gets disturbed. If the garage is also where the car and the lawnmower live, the answer is usually no.
How do I dispose of a bucket of old glaze?
Let it settle, pour off the clear water, and take the solids to a household hazardous waste facility if they contain metal colorants. Never pour it down a drain.
Is talc still a concern?
It is worth checking. Safety documents flag talc in some clay bodies and slips as potentially contaminated with asbestos, so buy from suppliers who state what is in the body.
Do I need a safety data sheet for premixed clay?
Ask for it. Suppliers provide them, and it is the only document that names what is actually in the body you are breathing near.
