From Introduction:

While the mysterious and often dark practices of the arcane is enough to keep the feeble minded and cowardly at bay a truly enterprising adventurer has a bold enough heart to journey into the darkened markets of foul mysticism, especially if the adventurer in question happens to know a bit about wizardry his self.

The Cauldron Supplier’s Guidebook is not an instruction regarding the arts of magical practice but rather a listing of commodities deemed valuable by those who engage in witches’ brews, alchemical formulas, potion craft, and experimental spell craft. Scattered across the following pages are the descriptions and listings for over two dozen items that may prove to be profitable for a supplier daring enough to deal in the ingredients of the arcane. A bit too spooky for the barbarian who shuns all forms of practiced magic, but extremely resourceful for the cunning individual who wishes to make a few extra coins off their dungeon crawling, forest wrecking, monster slaying expeditions.
