A Bit of History: American Brilliant Cut Glass.
It’s “lead crystal,” made with very pure silica and potash, plus at least 40% lead oxide to keep the glass exceptionally clear and keep it from shattering when cut. (Prior to lead, flint was used – but that’s a whole other kind of glass.)
After the glass was blown or poured into a plain mold, skilled craftspeople cut sharp, deep designs into the glass using rotating wheels. Any mold lines were carefully polished away.
The end result is gorgeous.
