Our high temperature furnaces are designed to execute heating parameters provided by the operator for heat treating gems in various configuration modes. We do not sell the “know-how” technology for heating customer’s gemstones; the “know-how” technology must be developed by the end-user. We only sell our furnaces and related gem treatment equipment as per specifications, capabilities and limitations.
It is like selling a rice cooker: the user should know what type of rice to select, slow or fast heating-cooling, cooking temperature and time, water, and other ingredients to cook the rice as desired. It is a certain recipe, not applied to every kind of rice.
If you are novice in this subject, I suggest to read and understand my book "The Heat Treatment of Ruby & Sapphire" before thinking to buy any of the equipment offered for sale. Likewise, for the potential, but seriously dedicated end-user, I suggest to take my course #610 offered periodically in Bangkok before buying any gem treatment equipment.
