Ordered water : Gypsum has been used for construction for millennia. The structure and water content of calcined gypsum, CaSO 4 ⋅0.5 H 2 O, has been under discussion until now: single‐crystal structure analysis (see picture: S yellow, Ca gray, O blue, H red) provides an ordered model that is confirmed by DFT calculations.
