The QX2 is the large hybrid quartz dish upgraded from the V1. The QX2 is twice as thick and has twice the dish volume of our original V1 Quartz dish. The dish is machined from GE clear fused quartz which has a nominal purity of 99.995% SiO2. The QX2 is precision machined to fit perfect into our new titanium Quartz Shield. This listing is for the dish only. 

We recommend adding a titanium QS (Quartz Sield) for an added layer of protection, increased thermal stability, and HE carb cap reverse compatibility.
