There are a number of glues
There are a number of glues that people use to hold pieces in place to get their work into the kiln. Here are some popular choices:
- Hairspray (sprayed into a cup)
- Super Glue (not recommended – can produce small amounts of cyanide gas when fired)
- Elmer’s white glue (often diluted)
- Elmers clear school glue (works best near edges where gases produced during firing can escape)
- Various CMC (carboxymethyl cellulose) based glues. Many glues advertised as “fuser’s glue” are CMC based. CMC is a food additive.
- Bullseye Glastac (not CMC-based)
My preference is Glastac. We did careful testing a few years back and Glastac was the ONLY glue that burned off cleanly 100% of the time.
Keep in mind that all these glues burn off before the glass fuses. I am not aware of any glues that survive to fusing temperatures and will hold pieces in place until then.
Hope this helps,
