The QS is the titanium Quartz Shield for the QX2 Quartz Dish. Machined from 99.9% pure ASTM B348 grade 2 titanium, the QS significantly increases the durability and thermal properties of the QX2 dish. 

The new QS serves three purposes:

(1) Protection: The most obvious purpose is protection from outside forces. This includes, accidental drops, direct contact with expanding coils, accidents with carb caps, etc.

(2) Thermal: Quartz alone has a low thermal conductivity which results in low heat transfer. With electronic nail setups the QS helps facilitate heat transfer up and around the walls of the dish and spreads the energy more uniformly through out the entire quartz dish. With regular torch setups the QS substantially increases heat retention time, therefore increasing the optimal temperature window time.

(3) Carb caps: Due to the large size of the new QX2 quartz dish, our current carb caps will not fit over the out side walls. However, attached to a titanium QS, the raised outer lip of the QS allows our titanium and quartz carb caps to now insert into the nail, rather than over it.
