Z4 is a ceramic partnership between the four members. Z4 realizes ceramic co-productions in which there is room for the creative input of the four group members. Z4 stands for "4 mushrooms", a reference to an old Utrecht pottery called "the four mushrooms". The interaction between potter, graphic artist and painters leads to unexpectedly beautiful results.
