Jacquard Alum 1Lb Pkg for Marbling

Very good quality and value for money

Quick delivery, reasonable price, effective product for marbling.

Works well

Well packed and nice to have instructions on pack of how to use.

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.

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

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

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

A Lifesaver After Being Sent the Wrong Product Multiple Times Be warned: many products are mislabeled as "Alum Powder" but are not the potassium aluminum sulfate needed for crystal growing. I learned this the hard way after three failed and non-returnable (alum = food product) orders. This Jacquard Alum Powder, however, is absolutely correct. The proof was in the dissolving. Unlike the others that did not dissolve, no matter what I tried, this melted completely into hot water to form a crystal-clear supersaturated solution. The growth process was swift and successful, resulting in stunning crystal clusters without having to repeatedly filter a cloudy solution - full of undissolved powder and impurities - like I experienced with other brands. The higher price of this Alum is justified by its purity and effectiveness. The quality control is exceptional, with no leftover particulates to ruin the solution. Don't waste your money on cheaper imposters—this is the one you need. Highly recommend!powder’s

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. 👍

Made the paint stick to the paper

Was recieved as expected

Un produits irritant pour la peau dont le paquet arrive explosé dans la boîte aux lettres... je ne sais pas combien de produit j’ai perdu, mais on peut me suivre à la trace.
