99.5% Pure Sulfur Powder, non-soluble, USA, 1 pound
Very versatile element, made in the USA. Many uses. Burning sulfur is toxic, but OW quite non-toxic and GRAS.
NOTE: I buy sulfur from vendors who advertise that they are selling 99.9% pure sulfur, but when the 50# bag comes, the label says it is not that pure. All the different vendors are selling sulfur that is 99.5% pure at best, no matter what their ad says.
