Synthetic quartz manufacture. An employee takes new synthetic quartz crystals out of the autoclave in which they were synthesised. Synthetic quartz crystals are produced in an autoclave by hydrothermal synthesis: crystallisation from high-temperature aqueous sodium silicate solution at high vapour pressure. Synthetic quartz is used in the electronics industry. Photographed at the Kristall crystal production facility in Yuzhnouralsk, Chelyabinsk region, Russia.
