How come Roman Glass isn’t in museums?

It is in museums. However, the Roman Empire was huge, and encompassed many areas with quality glass making traditions. Glass was used for vessels, beads, jewelry and many everyday uses....and glass breaks. The shards I use are coming out of ancient dump sites and being reworked into usable pieces, that are central design elements for me. I like copper, brass, stainless steel, silver as my accent metals. Tradebeads and Gemstones also roam about here.
