Color Mixing Glass ReferenceTable
Key benchmarks for color mixing glass.
| Process | Temp °F | Notes |
|---|---|---|
| Gather | 2100 | Clear marver |
| Work | 1800-2000 | Keep turning |
| Anneal | 950 hold | By thickness |
Annealing HoldFormula
Hold time (min) ≈ thickness² × coefficient for soda-lime
Hot Shop SafetyStandard
Always gather with punty or blowpipe — never bare hands near glory hole.
Marver Wipe
Wipe the marver between colors — chips embed and pop later in the bubble.
Final Inspection
Inspect finished work under bright, angled light to reveal surface defects invisible under normal conditions.
Fire Safety
Keep a fire extinguisher within arm's reach when working with heat, sparks, or flammable materials.
Safety Notes
- Hot glass above 1000°F causes instant burns — always assume tools and punty ends are hot.
- Ensure studio ventilation removes silica dust and combustion byproducts from glory hole and furnace.
