The Arts and Crafts movement developed from the 1870s onwards. It was inspired by the work and views of the designer William Morris and the art critic and writer John Ruskin. Their followers aimed to revive traditional handicrafts and avoid machine-made imitations. They often left evidence of the making process visible, as a reaction to the smooth perfection of late Victorian machine-made objects. The designer Christopher Dresser was unusual in enjoying the machine-made look. In ceramics, many Arts and Crafts designers and makers experimented with new glazes and finishes. These were often inspired by effects found in nature.
