Hi Min, simlar but different. Unfortunately i cant get a file small enough to attach here. That looks like it was formed at atmospheric pressure. The stuff i have was formed at about 5 to 8 times that so doesnt look 'fluffy'. Think something simlar to obsidian in texture. Hi Kelly in Ak yep we have a lot of toys... well the lab does us field ppl no so much. Will give that a go. Got any suggestions on ratios or just follow a basic glaze? Thanks

Fairly sure that it will be a sillica scale. Calcium based scales wouldnt form in well it was near ( not enough CO2). Could try putting some acid on the original and the baked product. There were other minerals present... as it had some black/grey hues, so most likely lithium/manganese. I may get one of the lab techn to pass it under the xrf and see whats in there. Was thinking thay i may need to add some sort of Flux but wasnt to sure what.

Hey, I work in a geothemal power plant. I can get my hands on some sillica scale that comes from the wells. I put a lump in the kiln at 1200C, instead of melting like i thought it would it came out as a crumbly white product. Has anyone got any suggestions as to what I may add to get it to behave more like glaze/ glass. Thanks
