This invention relates generally to methods and apparatus for the growth of high perfection quartz. Hydrothermal growth or culturing of quartz has been practiced for many years and has presently been refined to a point where virtually all quartz used for frequency control applications today is cultured quartz. Accordingly, it is an object of the present invention to provide a simple, inexpensive method and apparatus for the mass production of high perfection quartz crystals. It is another object of the present invention to provide a method and apparatus for the production of quartz crystals which exhibit few etch imperfections. It is a further object of the present invention to provide a method and apparatus for the production of quartz crystals which exhibit few inclusions.
