This (blue/white swirls) is a bowl I made recently from Alumilite resin and stabilized driftwood. I am in the process of making another one now for a customer. The coloring comes from added dyes and swirls from mica powders. The combinations are infinite. These are custom ordered and made. Please contact me if you are interested for design and pricing. Many different sizes are possible. Other example of some I made are also shown.
