Unaccounted for (natural gas): Represents differences between the sum of the components of natural gas supply and the sum of components of natural gas disposition. These differences maybe due to quantities lost or to the effects of data reporting problems.
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.
