I just wanted to share a tutorial I just made. It's a video tutorial showing how to make a glass mushroom pendant, using borosilicate glass. I start with pulling a stringer then making the mushroom. I think it came out really good , I was trying to make it easy to see exactly what I'm doing. I think mushroom pendants are a great place to start in boro and while there's lots of other tutorial videos out there, I couldn't find one that made it easy to see.
Glass Mushroom Pendant Tutorial
If you are going to attempt this yourself let me warn you to be careful when pushing the stringer in to make the mushroom, it is very easy to break the stringer and poke your hand. Another thing to remember is DO NOT stop spinning the glass when you push the mushroom.
