Deficiency may cause anemia, peripheral neuropathy, or damage to parts of the nervous system other than the brain and spinal cord. Good sources include: meats, bananas, whole-grains, vegetables, and nuts.
Most brass will melt at temperatures as low as 1,650ÂºF (900ÂºC), but a higher maximum temperature will give you a margin of error, and make the brass easier to pour. Select a furnace large enough to hold the crucible and brass you intend to melt. Consider the fuel you will be using.
Use a thermocouple to watch the heat. You want to heat the cast iron to 1300ÂªC / 2500ÂªF for fifteen minutes. You will know you have reached this temperature when the crucible's bottom is light yellow, nearly blinding in color. Remove the crucible from the furnace and heat. Add a teaspoon of borax to dissolve all oxides.
