Alum Powder (Ground Shabba) - Potassium Alum

Also known as: Ground Shabba, Fitkari Powder, Phitkari Dust, Powdered Alumen, Pickling Alum.

Chemical name: Potassium Alum (The naturally occurring mineral salt, finely milled into a crystalline white powder).

Visual Profile: A snow-white, fine crystalline powder that looks like table salt but carries a distinct, sharp astringency.

How to prepare: For a "Clarifying Wash," dissolve 1/2 teaspoon in a liter of water. For a "Traditional Face Mask," mix a pinch with rosewater to create a skin-tightening paste.

How it’s used: A secret ingredient in Gourmet Pickling to keep cucumbers and peppers incredibly crisp; a natural Deodorant Dust for footwear; a high-efficiency Water Sedimentation agent; and a classic "Styptic Powder" used by barbers to instantly seal minor nicks.
