Postcard - ‘Mercury and fire symbolize the opposites water - fire’.
Water and fire both have a dissolving effect, by which the coarse substance is refined. Michael Maier (1568-1622) describes phases from the alchemical process in Atalanta fugiens, 1618.
There is a brief explanation of the image on the reverse of the card.
