The blanks maintain the 6:1 diameter to thickness ratio.

** PL= Plano flat on face & base.

Quartz and fused silica blanks have the lowest expansion coefficient and are the most stable material. However, they are also the most expensive. Their internal lattice structure is totally crystalline in nature.
