The wild orange glow of the melts is mesmerizing often forming slowly moving patterns as they cool. I’ve tried to photograph them before (point and shoot method on automatic) but just get orange fuzz. I finally decided that the camera just cant focus on the intense heat source (they come out of the ovens at 1950 to 2200 degrees. Putting the camera into full manual allowed me to finally get some decent shots of hot stuff
The melts are poured out in to a tray of conical molds. What you see on top is the molten glass. The metals fall out to a bead in the tip of the cone.
