Liquid Kato PolyClay
To achieve the same effects that I do with my beads, you will need clear liquid Kato PolyClay. There are multiple places to purchase it online, and if you live in the United States you may be able to find it at your local craft store (Hobby Lobby stocks small bottles of the clear).
Heat Gun for Faux Glass
You will need a variable temperature heat gun that can hold a steady 250℉-300℉, and allows you to adjust how fast the air comes out. You do not want one that only has an option to turn the heat on low or high. I prefer having one that has a stable base so that the tool can be used hands-free safely because having both hands available makes my faux glass techniques much easier. That being said, you absolutely can make them while holding the heat gun in one hand and rotating the bead in your other hand.
