What Is Smelting And Sintering

May 30, 2019· sintering is the process of combining materials into a solid piece using heat.Think of sintering as dry smelting; in that materials used are fused together, but do not become a liquid.From the first ceramics produced 24,000 years ago, to some of the first in-tact finds from around 6,000 years ago, early sintering was used to create makeshift.
