From tiny threaded quartz pins to 36" machined quartz plates, and everything in between, WCQ consumes as much of our raw material as possible in the production of various and diverse styles of parts. This maximizes yield and keeps our prices competitive. Our long substantial relationship with GE Quartz as an Authorized Fused Quartz Distributor as well as Tosoh and Saint Gobain allow us to obtain large-scale raw materials (tubes, rods, and boules) while others struggle for attention and supply at one time or another.


We stock significant raw material inventory of the various grades of fused quartz, clear and opaque, from beach sand as well as from nature-formed raw crystal.
