Has anyone tried to add glass to rocks? What did you make? Did it survive?

This rock was black before it went into the kiln to get it hot. For some reason, the glass kept bubbling up after I applied it. You can see the bubble holes really well on the second photo. I didnt have to add very much torch heat to the glass for it to bubble up. It came out of the kiln in one piece (both the rock and the glass).
If the glass doesnt crumble right off the rock soon, Im gonna see what else I can do with this.
PS. I dont know what kind of rock it was. I got it off of the beach in WA.
