Jacquard Alum 1Lb Pkg for Marbling

I bought this as a solution for ants.Mixing 1 part to 9 parts sugar was great for them to take it back to their nests as my garden suffers from multiple ant nests and I've finally got annoyed by all their mounds

I use this to dip aquarium plants, rocks, wood etc to eradicate pest aquarium snails. It works perfectly, 1 tablespoon per gallon and soak everything for 3 days then rinse it off. Doesn't harm plants but kills not only snails but more importantly snail eggs too. Best method out there, works 100% of the time.

Very good value and does the job bought for very well

Good amount for money. It will do plenty of science experiments.

Good although they should add an extra layer of plastic just in case it rips in transit. Used for marbling and science crystal projects.

It's worth pointing out that this is potassium aluminium sulphate, KAl(SO4)2 - at lease mine was. Everything else was satisfactory.

Good product, arrived fast and seems a reasonable price

As expected

The media could not be loaded.  It worked perfectly for removing broken taps.The solution needs to be saturated and kept close to the boiling point. The alum will corrode the iron in the tap and it will turn it into that black, spongy, brittle stuff, seen on the paper towel. That makes it easy to clean and to re-tap. Obviously, the part needs to be non-ferrous, in my case it was ToughMet. The reaction creates those bubbles that can be seen on the inside of the part in the video. For my application the tap was corroded in approx. four hours, so be patient and keep replacing the evaporated water every now and then.There are people recommending an aluminium container. I used a glass container and I put a piece of aluminium in the solution. If I am not wrong, the aluminium that is displaced from the alum salt needs to go somewhere, so it was probably deposited onto the aluminium piece (this is my personal opinion, as a non-chemist).To create a saturated solution like the one in the video I used just over one pound of alum salt.

Arrived 1 day before first estimation, not bad. On line tracking I would say next to useless. Used the product to remove a broken drill out of copper bar. Worked perfectly. Excellent stuff. Will remember for next time. 👍

pour mes plantes - excellent produit

Lo compré para hacer mordiente sobre papel.Lamentablemente llegó en mal estado, rota la bolsa que lo contenía y con pérdida de producto.No volveré a comprar a quien envía de forma tan precaria.

I made crystal tea candle holder. The alum was easy to work with.
