Recent experiments in a silver lined autoclave [quartz growth]

A research program to develop hydrothermal quartz culturing equipment and processes capable of economically producing quartz is discussed. The initial phase covers the production of the highest quality quartz, given state-of-the-art sodium carbonate process equipment. The second phase seeks to establish definitive relationships between process variables and quartz quality. Given the results obtained in phase I and II, the third phase involves the production of high-purity quartz based on optimized process variables
