Sharp edges…


I have had this same problem on some of my random firings. Normally sharp edges mean that either the mold has not had enough wash or the glass has overfired a bit. I’ve noticed that during warmer weather my kiln fires slightly differently than in colder weather…I don’t know if this could have an effect or not would love comments from others regarding this occurance. You should be able to sand these edges with a file or sanding block, then refire to polish.

I’m no expert, but I hope that helps.
