Hi, we lived abroad for 7 years and I am just now returning to glasswork. My equipment and supplies were in a storage facility without heat or a/c. I fired my first pieces and they all migrated to the middle of the kiln shelf and fused together. I used the Basic 6 schedule from this site BASIC 6-Segment Firing Schedules.
http://system96.com/Resources/FiringGuideFahrenheit.pdf with System 96 glass. I suspect the temp was too high but fear there might be other contributing factors.

I used Thinfire shelf paper that no longer looks white from being in storage so long. It looks beige. Does shelf paper deteriorate?

I used to fire my kilns in my kitchen but have room in the garage in our new house. It was colder (low of 40 F0 and rainy when I fired. Does the garage need to be heated?

Thanks in advance for your kind assistance.

Diane

The old version of thinfire would shrink and curl up. Which may be the cause of your problem since your pieces are small.

Is there a chance your shelf was stored in such a way that may have allowed it to warp slightly?

Also, you might want to weigh down the edges/corners with some kind of kiln furniture.
This will keep it from curling so much.

Thanks JIM. I will check my self. The kiln furniture is a great idea!
