Strengths Simple, smooth clay with a long history of use.
Weaknesses I haven’t been particularly taken with it over any of the other clays.
Alternatives & Substitutions I’d use kaolin clay instead as my first choice. After that, another smooth clay like French green clay would be a good choice. I would not use bentonite clay instead.
How to Work with It Take care not to inhale large amounts of Fuller’s Earth/Multani Mitti clay. When blending with liquid I recommend adding small amounts of clay to the liquid, whisking until smooth before adding more clay. Add at trace in soap making (start with 1–2 tbsp/500g of oils).
Storage & Shelf Life Stored somewhere cool, dark, and dry, Fuller’s Earth/Multani Mitti clay should last indefinitely.
