Stephen, thank you for your
Stephen, thank you for your reply. You are right I am new to fusing so I may be making assumptions that are incorrect. The area I am taking about was very dull and evenly frosted though not “grainy”, the glass was black that had been strip cut(tried to take a pictures but I didn’t have success) the other glass seemed fine. I decided to sandblast and fire polish which seemed to take care of the problem area. Would this lend itself to be devit since it didn’t reappear after the sandblasting and refire? I truly appreciate your help and this forum’s guidance!
