Unlike traditional quartz nails, the Highly Educated nails are machined from a quartz slab and not made from tubing. The dish is machined from GE clear fused quartz which has a nominal purity of 99.995% SiO2. Precise machining of this semiconductor grade quartz allows the bails to be reverse compatible with tools like their Carb Cap V2, UniTi Cap, or ParTi Cap.
