Awesome for fresh cut hydrangeas.
A true miracle saver for fresh cut hydrangeas dip the hydrangea in this and it will stay looking beautiful in that water for at least a week. I don’t know what you would use this spice for, but it works for the hydrangeas.

Perfect for DIY Natural Deodorants – Pure and Easy to Work With
I’ve been making my own natural deodorants for years, and this alum powder is exactly what I needed. It’s finely ground, easy to dissolve, and blends well with my other ingredients. Using it makes the whole process faster and smoother. I love that I can trust the quality and purity of the product—no strange odors or clumping. What I love most: • Fine texture, dissolves easily • Great for DIY recipes • Feels clean and natural on the skin • Makes homemade deodorant even better Final thoughts: If you’re into natural self-care and like to make your own products, this alum powder is a must-have. I’ll definitely be buying it again.

Helped my cut wilting hydrangeas
Mixed results using alum for my hydrangeas. I lucked out this year and my hydrangeas have bloomed prolifically. I normally try not to cut them until fall but with heavy rains the massive bushes took some damage and so I decided to enjoy some inside. Way too much wilting going on so I decided to give the alum a go. After waiting four days for this to arrive I recut the stems minimum one inch and then dipped into the powder. So far the results have been mixed but it’s worth the small price and a good item to have in my pantry. I also tried using it as a mouth rinse on a troubled tooth as I read here in the reviews. Tried once so I have no idea if it will help but again, certainly worth a try. Great purchase.

⭐ 5 estrellas – Excelente calidad, funciona y dura muchísimo Compré este bote de alumbre y quedé encantada. El producto viene bien presentado, limpio y en un envase resistente. La calidad del alumbre es muy buena: se nota puro, fino y fácil de usar. Lo aplico después de la ducha y me gusta porque deja una sensación fresca y limpia sin perfumes fuertes. Otra cosa que me sorprendió es lo mucho que rinde. Con muy poca cantidad es suficiente, así que el bote me durará bastante. El precio me pareció excelente para la cantidad que trae. ✔️ Lo que más me gustó: • Producto puro y de buena calidad. • Viene bien presentado y en un envase resistente. • Se aplica fácil y rinde muchísimo. • Excelente relación calidad–precio. ❗ A considerar: Si nunca has usado alumbre, puede sentirse un poco “seco”, pero es normal.

Alum is good to keep Hydrangeas looking fresh in a bouquet!
I have been flower gardening for over 25 years, and like to make bouquets for friends, relatives, and bring them to restaurants we frequent in our area. A new gardening friend and I combined a couple of things to extend hydrangeas in bouquets... If you put hydrangeas in a bouquet, unfortunately they wilt very quickly, even using the usual floral extender you normally use in the water. However, if you cut the end of the hydrangea stalk at an angle, dip it in water to wet the end and then dip it in "Alum", then place it in the vase, the hydrangea will last MUCH longer. This little trick may actually bring back hydrangeas that are already wilting. You should also add one or two shakes of salt a day to the water in the vase as well (not too much though, as the other flowers won't appreciate it). I jokingly said our experiment felt like it was, "An 8th Grade Science Fair Project"! LOL! But it works, and that's what counts!!!

Great Quality for Pickling and Crafts
McCormick Alum is exactly what I needed for my pickling recipes. The quality is excellent, and it dissolves well without clumping. I’ve also used it for a few craft projects, and it works just as expected. The 1.9 oz size is perfect for occasional use and comes in a sturdy, resealable container. Definitely a reliable product from a trusted brand!
