look at your piece but do not, as this can be dangerous and will result in cracked projects.
4. Do not reuse the kiln until it has completely cooled for at least 30 minutes. Continuous use without
cooling can cause damage to the kiln.
5. Your fused project must cool completely before removing from the kiln. This can take up to 40-50
minutes. Once cooled, you can remove the fiber paper from the back of the fused project by rubbing
the surface with a wet paper towel or cleaning the project under warm water.
Troubleshooting
Problem: Cracked glass in the kiln during firing.
Solution: Clean and dry glass thoroughly. Make sure glass being used has the same Coefficient of
Expansion (COE).
Problem: After glass project cools, fused project cracks
Solution: Cool more slowly. After removing the kiln form the microwave, leave the lid on for at least 30
minutes in an area free of drafts.
Problem: Fused project has sharp edges.
Solution: use a glass file or fingernail file to remove burs.
Problem: Glass embeds itself into kiln walls or base.
Solution: Allow both glass and kiln to cool completely. use a utility knife to carefully cut and remove
glass from the kiln.
Problem: Cracks, blisters and/or loss of interior kiln coating.
Solution: This should not impact the operation of the kiln. If large areas of the coating are damaged and
the glass is heating unevenly, a replacement top is recommended.
Problem: Dichroic glass shatters and breaks during fusing.
Solution: This could be the result of heating the glass too rapidly. Try reducing the power of the
microwave by 50% for a longer length of time.
