crucible should be heated up to 600°C (1100°F) on low power, before the full heating rate is used to reach 950°C (1750°F), or the desired working temperature if higher.
Made with high quality bonded clay graphite and premium grade raw materials, these crucibles are designed to handle temperatures up to 2900°F, and therefore, can handle the harsh direct heat from open flame foundries and high frequency induction furnaces. They can be used to melt both precious metals and ferrous and non-ferrous alloys.
— This ancient Gold Refining method is one in that the nitre must be " projected " upon the gold just before it melts, as it has little effect on molten gold. The method is still in wide use. The bullion is melted in clay crucibles, and a little nitre (potassium nitrate) or sodium nitrate is thrown on to the surface of the metal.
