My latest beach glass pendant took a dive into a hot bath of liver of sulfur. I'm thinking it was too hot. The glass cracked in several places. The cracks aren't all that visible, until the piece is held up to the light. It is still wearable but not sellable. So, I have myself another new necklace (which is okay.)
This experience is "another learning experience." (There are just too many of those!) If the water for the patina is heated in the microwave, wait until it cools down.
But I do like this piece with a patina.
