Product Overview


  • Non-Irradiated
  • Kosher

Alum is the chemical compound aluminum sulfite and is also referred to as ammonium aluminum sulfite or ammonium alum. Alum is used primarily as a pickling agent, to add crispness, or as a dye fixer (mordant).

Suggested Use

Use in home pickling to add crispness. For recipes that call for powder, granules can be ground in a spice grinder.

Posted by iHerb Customer on November 5 2017 | Verified Purchase

I ENTERED ON YOUR SEARCH WEBSITE AMMONIUM BICABONATE.it came to aluminium granule! If you dont have AMMONIUM BICARBONATE, please don't redirect to some powder which doesn't have the same application in food!!! Iwasted my money to some product that i dont haver the use. Full BULLSHIT. shame on you!

Thanks for your feedback!

Does what it should.

I bought this alum to use as a dye mordant and it works perfectly well as such. As for iHerb, they are great, their products are reasonably priced and shipment was speedy. This was a considerable plus for me as I had already mixed my dye bath, thinking (foolishly, as it turned out) that I could buy alum locally in Devonport. Thanks so much iHerb!

To the reviewer who returned this item because you it won't make crystals - that is wrong, I bought this solely to use for crystal growing and it works perfectly fine. Great item, great quality and quantity for such an economical price. I've been experimenting growing Alum crystals and it works perfectly! Will be ordering more.

Thanks for your feedback!

I love it!
