1kg bag ALUMINIUM SULPHATE 17% Iron Free Alum Al2(SO4)3

Does what it was intended for, as a mordant. Worked perfectly.

Bought this as my Great Dane split a nail and I couldn't stop it bleeeding, and every time it healed he knocked it and started over again..... I put half a teaspoon on some cotton wool and bandaged his nail and toe and when I checked 24 hours later it had completely dried and was able to seal the broken nail wil super glue

It works for the purpose I bought it. Hydrangea has beautiful blue flowers

My son asked to order for their art biology project. In terms of chemistry effect it worked. My son asked me to order more.

good quality a plus+++++

I bought this to turn my potted pink Hydrangea blue, despite adding vinegar to help break down the product, the hydrangea is still pink. So a waste of money for me but maybe i did something wrong?

Snapped a point in my dart and this made it super easy to remove.

Used it to Grow a crystal with my nephew
