I have been using shards of a type of glass that has lots of silver in it and therefore changes color depending on the chemistry of the flame. These three marbles are about 1 1/4 inches in diameter. They vary from brown to green with some "oil slick" patches.

Ever since taking Wil's marble class I have been going crazier making marbles. This one is about 1 1/4 inches in diameter. It is a vortex marble - it looks like a tornado is inside.

I am finally getting pictures posted from the marble class Kate and I took at Salado Arts Workshop. Wil "Boxfan" Menzies moved to Salado and within a couple of weeks was teaching here. We had a great couple of days making marbles and watching Wil demo. A day without marbles is like a day without sunshine (or something like that!) :) The marble is about 1 1/4 inches in diameter and the mushroom pendant is about 1 inch by 2 inches.
