I found some unusual pieces of kiln furniture in the bottom of a used (paragon) glass kiln I bought. They are 4 pieces of the same material as kiln shelves are made of.
Each piece is 4 inches long, 3/4 inch wide, and about 1/2 inch high.Then, there are 15 pins/nails sticking out of it, the pointy ends so it is sharp and spikey.
Other than these 4 pieces, the only other thing in the bottom of the kiln was a kiln shelf.
Any ideas on what this might be.
