Alum powder is a crystalline powder that is most commonly used in pickling; it keeps pickles firm and crispy.

Alum powder is often used to firm and crispen pickles by letting them soak in a sealed brine solution of water, vinegar, salt, spices, and alum powder for several weeks. Cucumbers should be pickled at the peak of freshness because they will become soft after a few days. Use up to 1/4 teaspoon of alum per pint of solution.

Alum's tissue-shrinking properties gave it a starring role in multiple episodes of the cartoon Looney Tunes in which alum was shown to comically shrink the characters' heads and pucker up lips.

“ Yes the package did arrive. Now I need to scrape the hide(fleshing out) and get the solution of salt water and alum to soak the hide(a tanning process). The alum helps the hair stay on the hide- which is technically called a pelt. Your company was the first one I found that I could purchase the quantity I needed. Thanks.”

“Did you know that you can get rid of ticks by feeding powdered alum to horses every day, just 1/4 teaspoon will do it. And that sample of the cereal was awsome!

“We are SO thankful that you had the Powered Alum in bulk! We have a different use for it than you probably imagine...We have a older horse that has founder, we were told if we give him 3 tablespoons of it a day his sore feet will get better. We were getting the 2 oz. jars at the store and saw improvement but was SO expensive to buy it that way. That's when we found you online. Now we can get it in bulk so he will be much better soon!Even with the cost of shipping it is worth it to make him feel better! And LOVED the almonds you sent as a gift!”
