A 36.4g sample of Sulfur in the form of a single large crystal. This was grown from a hot solvent solution with very slow cooling over several days time. This process results in large crystals that have a beautiful shiny geometric surface and are a much more attractive alternative to the prills or powder forms of sulfur commonly offered elsewhere. The process also results in a substantial increase in purity from the starting material. Purity is at least 99.999% but probably higher. Please check my Bonanza store for more element samples. I have almost every collectible element available. Thanks for looking.
