Welcome to Cosmo Glassworks.

I make glass marbles and paperweights. Occasionally some other stuff.

All of my work has been fully annealed in a kiln to ensure long life. Also, while I make every effort to ensure the photos are accurate representations of the actual items, the limitations of computer monitors mean that the photo you see will not always exactly match the actual piece.

I am currently working on a book about how to make marbles. I plan to have it available by the end of the year. If you want to be notified when it becomes available, please sign up for my newsletter.
