Blue vitriol, as well know it, is hydrated copper (ll) sulphate, meaning CuSo4.5H2o.
That SH2o is the water of crystallization or the water of hydration. Those 5molecules of water simply constitute the crystal I.e, they merely embedded in between CuSo4 atoms.
When blue vitriol is heated, those water of crystallization escape out of the crystal and what's left is amhydrous copper sulphate or crystallization.

blue vitriol - CuSO4.5H2O
when CuSO4.5H2O is heated it decomposes to form CuSO4 which is a white substance
