We prefer to use Bullseye glass; this is the only brand that has different colors that are compatible. For casting we sometimes use Banas glass as well. This glass is not compatible and the glass you use should therefore come from the same batch. It is possible to use your own glass, but we cannot guarantee the result.
Prior to your project, discuss the timeline with one of our advisors. We do not have glass in stock. We place orders for glass per project. Take into account a delivery time that can increase depending on how common the glass is (less common = longer delivery time).
