Solidus

A solidus is a mixing instrument used in metallurgy, chemistry, and jewelery to melt or blend metals and other materials. It consists of a container—often made of fire-resistant material—and a paddle or stirrer that helps combine substances evenly. The term can also refer to the temperature at which a material transitions from liquid to solid. Overall, a solidus ensures precise melting and mixing processes, critical for creating alloys or conducting controlled chemical reactions. It's essential for achieving uniformity and quality in metalworking and materials science.
