COPPER PYRAMID Made of pure copper, this 6 3/8" truncated pyramid is essential to the performance of Agnihotra. Why copper? According to the Vedas, copper and gold have special healing properties. These metals also have special conductive properties. It is best to keep objects made of other metals away from your Agnihotra pyramid once it is in use, as they may detract slightly from the effects of Agnihotra. Manufactured by Copperworks in the U.S.
