Single Strength 3mm Standard fusing glass 1 hour Most projects
Double Strength 6mm Slower heating needed 2 hours Thick projects, bases
¼ Inch 6.4mm Extended firing times 2.5 hours Architectural, heavy pieces
3/8 Inch 9.5mm Professional thickness 4+ hours Large installations
½ Inch 12.7mm Industrial applications 6+ hours Countertops, heavy art

Mold and Slumping Materials

Material Type Temperature Limit Reusability Cost Best For
Ceramic Molds 2000°F+ 50-100 uses $15-80 Bowls, plates, repeated shapes
Plaster Molds 1800°F 10-20 uses $5-25 Custom shapes, one-offs
Metal Forms 1500°F 100+ uses $20-150 Simple curves, draping
Fiber Paper 2300°F Single use $2-5/sheet Texturing, mold release
Vermiculite 1800°F Multiple uses $8-15/bag Supporting irregular shapes
Sand 1800°F Unlimited $3-8/bag Free-form slumping

Common Firing Problems and Solutions

Problem Cause Temperature Range Solution
Devitrification Too long at high heat 1450-1500°F Shorter hold times, higher temp
Cracking Thermal shock Rapid cooling Slower cooling rates
Bubbles Trapped air/gases 1200-1300°F Slower heating, thinner layers
Sharp Edges Under-fired Below 1450°F Higher temperature or longer hold
Over-fired Too hot too long Above 1500°F Lower temp, shorter time
Stress Marks Poor annealing 900-1000°F Proper annealing cycle

Glass Preparation Checklist

Step Process Tools Needed Time Required Critical Points
Design Pattern creation Paper, scissors, markers 30-60 min Accurate measurements
Glass Selection COE matching Compatible glass 15-30 min Same COE numbers only
Cutting Precise cuts Cutter, pliers, grinder 1-3 hours Clean, accurate edges
Cleaning Remove oils/debris Glass cleaner, cloths 15-30 min Fingerprint-free surface
Assembly Layer arrangement Tweezers, brushes 30-90 min Minimal air gaps
Kiln Prep Shelf preparation Kiln wash, brush 15-30 min Even, thin coating

Safety Considerations

Hazard Type Risk Level Protection Required Emergency Action
Glass Cuts High Safety glasses, gloves Clean wound, bandage, seek medical care
Kiln Burns Very High Heat-resistant gloves, apron Cool with water, avoid ice, seek medical care
Glass Dust Medium Dust mask, ventilation Fresh air, rinse eyes/mouth
Chemical Fumes Medium Respirator, fume extraction Ventilate area, fresh air
Eye Injury High Safety glasses always Flush with water, no rubbing, seek medical care
Fire Hazard Low-Medium Fire extinguisher nearby Electrical disconnect, proper extinguisher
