The HD firefly kit produces both silicone RTV molds and HD casting patterns.  The hyperbaric light chamber utilizes air pressure instead of a vacuum to eliminate air bubbles. Up to six RTV molds can be made in the chamber per cycle with an averaging curing time of 6 minutes. The system features a stainless steel stand, three stainless steel mold frames, a timer, power supply, spin bag, and air coupling. See the HD firefly kit and more great tools at Stuller.com/tools.
