Production — Stalite
The calcareous tuff impedes the bloating process of lightweight aggregate production. At 2,000 degrees F (1,000 degrees C), the calcite simply calcines. At high temperatures of over 2,200 degrees F (1,200 degrees C), diabase rock (specific gravity of 3.0) melts to a glassy type of rock with no specific gravity change.
