I watched some videos on making fried marbles (or baked marbles, since that's a common way to do it now) and did some image searching for project ideas. there's some pretty cool stuff out there that people have done that looks super simple. I love this one - on the lookout for small round marbles now!
I have really been wanting to make some for a while so I finally picked up some flat marbles at the Dollar Tree and E6000 from Michael's to try this little number out.
I made some wire bails while I baked my marbles and whipped up a few quick pendants during nap time.
I noticed that the darker ones didn't shatter as much on the inside. I don't know if they should be heated longer or what. I did mine at 500°F for 30 minutes. they sizzled and popped when they went into the ice water like it said they should in the tutorial, and I could see the light colored ones had small fractures throughout immediately. I left them in the water for 15 minutes waiting for the darker ones to finish up, but they pretty much had just a few larger cracks through them and that was it. I tried re-baking some, and that didn't really do anything except make some of them break apart.
I might try alcohol inks someday if I revisit this type of project so I can just use the clear ones that crack really nice and make them whatever color I want.
