A tank furnace is a large industrial furnace used primarily for melting glass. Imagine a giant, super-hot swimming pool filled with molten glass! ๐ These furnaces are typically constructed from refractory materials that can withstand extremely high temperatures. Raw materials like sand, soda ash, and limestone are fed into the furnace, where they melt and mix. The molten glass is then drawn off for shaping into various products like bottles or windows. Tank furnaces operate continuously for years. ๐ฅ They're an integral part of glass manufacturing.
