A clay triangle, physically, is three sets of two wires with the ends twisted to form a triangle. High tamp. clay (like fireplace clay) rods are placed on the wires before uniting them to form a open-centered triangle rimmed with flame resistant material.
This allows direct contact of the open flame to the crucible, which usually contains a substance that melts at fairly high temperatures. Also, crucibles have bottoms that are smaller than the circumference of the main body, so placing it into the open triangle gives stability to the set up to prevent tipping and spilling the molten contents.
