The main base of our Black Sun Pendant consists of; A blend of fine Copper, Steel, and Brass Metals are added along with our special "Black Sun Blend" to create our Pendants. To Create our Blend, we use very fine metal Black Iron Oxide mixed 50/50 with Bionized gold bearing Black Sand. Which contains a broad range of heavy minerals and an array of fine Quartz.

He did so by improving on Wilhelm Reich’s Orgone Accumulator with a similar device made of metal particles but cast in resin. Welz coined the term Orgonite and trademarked the name.
