Could a kiln to melt metals used?

I have searched the production of rings in, but silver melt gold and other metals Quality you would have a $ 1000 cottage, which still reached only about 3,000 degrees Celsius. I have reached some ovens, the temperatures of 6000 degrees centigrade, for just $ 500 belongs to $ 700. Would it be possible using a furnace, like a Evenheat for such melts? Another detail that I could add some jewelry, I rejoice in tungsten make some, but I've seen, it is necessary to reach extreme temperatures in order to achieve this (my data are wrong, but ~ 6200 ° F). How could this be possible?

Your data is wrong – you do not go as high temperature and no pottery kiln on earth is 6000F – in fact, very few refractory (Protective materials for the furnace) can survive up there 3000F This table shows the casting temperatures for various metals http://www.mikegigi.com/meltmetl.htm # MELTG and similar charges can be found on other sites than mine. Platinum is the only metal to 3000F and it requires extraordinary heating (and eye protection) Requirements. Pottery kilns that) go to cone 10 2381F (be able melts all other metals. But a disadvantage is pottery that they are too bulky and intentionally a lot of time because ceramic heater requires a heating rate that they are "mature", that also allows starting, chemically instead of water and glass. Metal heating can be done much faster side, depending on how you can schedule a time to ring in decision making, you can pot heat the metal with a torch in a small and Spin cast, or you can build a small foundry for less than $ 1000 – look up the page on the first link above for my rather crude but workable Setup.
