In 2012, Rachel Dein showed the owners of a flower-shop a plaster-cast tile she had made from a bouquet. They were impressed, and soon the UK artist began receiving commissions to make more of these modern “fossils.” Dein's method is simple: she presses flowers into wet clay and then pours in a mixture of plaster and concrete to produce a tile. The dry tiles can be left unadorned or be painted.
