I have attempted 3 different drape projects using a stainless steel mold covered with boron nitride. Each time my project turns out ugly…. having milky and rough glass. I’ve wiped off most of the nitride, and I still have not come up with a solution. The more I use the mold, the worse things becomes.
What is causing this?
How can I fix it?
What is the best way to remove the residue? I’ve already tried soap and warm water as well as rubbing alcohol.
Hi, the glass will take on any marks or texture on the moulds. The Boron nitride will always leave texture which can alllow it to get trapped in the glass, try using kiln shelf paper between the glass and boron coated mould.
Don’t worry that the paper may not be conforming to the mould as it fires it will go with the glass, hope this helps
