jrgpots Posted September 9, 2019 Report Share Posted September 9, 2019 Has anyone used welding powders in a kiln using a similar technique as salt firing. I wondered what type of effects I could achieve by spraying welding powder on hot pieces during thr firing cycle? If it has been done, can i get the protocal and info to research. pics would be great. Jed Link to comment Share on other sites More sharing options...
liambesaw Posted September 9, 2019 Report Share Posted September 9, 2019 Isn't that stuff actual metal though? I'd think it would need to be an oxide or salt to really do something, but if you have a junk kiln you should try it! Link to comment Share on other sites More sharing options...

If it’s what I am thinking, some oxides, some high temp zirconium and yttrium, silica and alumina (Figures). Some are made to wear away in a controlled fashion, some are made to bond a lubricating surface to metal for sliding parts. Many are some composition of cobalt and chromium. I know them for protective surface coatings for turbines and the like. Not sure how that will work out in your everyday kiln. There are at least four or five categories of the se compositions melting from say 400C to a high of maybe 1300C. I would only caution that you think about the ingredients and safety before doing this. Link to comment Share on other sites More sharing options...
jrgpots Posted September 10, 2019 Author Report Share Posted September 10, 2019 based on the responses, this has not been tried much. I have a throw away small gas kiln, so i think i have a new experiment Jed Link to comment Share on other sites More sharing options...
