McCormick Alum, 1.9 oz (3 Pack)

Arrived within the expected time frame. It’s Alum but not the Alumni kind. Sorry not sorry

I needed alum for a canning recipe and was unable to find it in stores. It came quick and was exactly what i needed!

Quick delivery, good product

Had a hard time finding this in my local grocery store.

I didn't zoom in to see the granule size - it's like salt, so it takes some time to dissolve and beat up. I really wish I bought the powder kind but was unfamiliar with this brand. It also weighs/measures different from powder by a considerable amount, so I had to adjust my recipe. I was sanitizing aquarium plants, and the wrong strength solution can be deadly.

Used for canning.

Very useful

Cant find in local grocery stores anymore. A great remedy for canker sores. My friend's son was asking for help, he got rundown and he had a canker sore in his mouth. He used some on it and it was gone the next day. He had been unable to eat for 2 days, so he has his own tin at home now.
