At very low pressure, the distance between the evaporating surface and the condenser is approximately equal to the mean free path of the vapour molecules.

They started breaking down with the discovery of antimony, bismuth and zinc in the 16th century. The associations below are attested from the 7th century and had definitely stabilized by the 15th.
