Chemistry - Atoms And Bonding - Learning Points. Diamonds take a long time to form in the Earth's mantle. Made only of carbon scientists have tried to produce them in the lab. The HTHP process, simulates high temperature, high pressure found in the Earth's mantle to produce small diamonds. The CVD, Chemical Vapor Deposition method, is a more successful method. It uses diamond 'seeds', hydrogen and methane to produce carbon atoms that latch on to the seed. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
