My local hardware store sells flours of sulphur for gardeners. It&amp;#x27;s used for acidulating soil, and for combatting some kinds of fungus. I don&amp;#x27;t know why anyone would want to regulate the sale of elemental sulphur; it&amp;#x27;s not toxic, caustic or explosive. It&amp;#x27;s less flammable than a piece of wood.</text><parent_chain><item><author>greenbit</author><text>Those sure were different times.
