what temperature does brass melt
Brass has a relatively low melting point compared to iron, steel, or gold, but it still requires a special furnace. Many beginning metalworking hobbyists start out with aluminum, which is easier to melt, but brass is often the next step.ost brass will melt at temperatures as low as 1,650ºF (900ºC), but a higher maximum temperature will give you a margin of error, and make the brass easier to pour. 1 Select a furnace large enough to hold the crucible and brass you intend to melt. 2 Consider the fuel you will be using. 3 3 Edit step.

who developed surgical techniques to prevent the entry of microorganisms into wounds
Joseph Lister, 1st Baron Lister, OM PC PRS, known between 1883 and 1897 as Sir Joseph Lister, Bt., was a British surgeon and a pioneer of antiseptic surgery.
