"I started making Ruby New Mexico Glass just recently, after discovering
of red cullet (broken glass shards) that I had bought from the Fenton
Company in 1975 but couldn't use because it was incompatible with my
clear glass at the time. Four decades later, this
cullet turns out to be
perfectly compatible with the clear glass that I use now, so we've been
experimenting with a lot of new shapes, sizes, and patterns. Ruby New Mexico glass appears red in transmitted light, while at the same time it reflects the vibrant blue hues and patterns of my classic New Mexico glass."
