What do you mean with "agglomerated" and which situation are you referring to?

It means,they will be caked.
Zinc sulfate heptahydrate looks like crystalline powder,and it likes the snow melted,but I don't know what's reason makes it caking~~~`

Ok, now another question: it is a result of a laboratory reaction (sulphuric acid + zinc or zinc oxide, hydroxide, carbonate) or it's a pure compound buyed?
I remember that sodium hydrogensulphate NaHSO4 I get from a personal laboratory synthesis (sulphuric acid + sodium carbonate), had exactly that appearance.
