Resist

Longquan celadon vase, 14th century; the unglazed medallions were coated with a resist before the vase was coated with liquid glaze.[1]

A resist, used in many areas of manufacturing and art, is something that is added to parts of an object to create a pattern by protecting these parts from being affected by a subsequent stage in the process.[2] Often the resist is then removed.

For example in the resist dyeing of textiles, wax or a similar substance is added to places where the dye is not wanted. The wax will "resist" the dye, and after it is removed there will be a pattern in two colours. Batik, shibori and tie-dye are among many styles of resist dyeing.[3][4]

Wax or grease can also be used as a resist in pottery, to keep some areas free from a ceramic glaze; the wax burns away when the piece is fired.[5] Song dynasty Jizhou ware used paper cut-outs and leaves as resists or stencils under glaze to create patterns.[6] Other uses of resists in pottery work with slip or paints, and a whole range of modern materials used as resists.[7] A range of similar techniques can be used in watercolour and other forms of painting.[8][9] While these artistic techniques stretch back centuries, a range of new applications of the resist principle have recently developed in microelectronics and nanotechnology. An example is resists in semiconductor fabrication, using photoresists (often just referred to as "resists") in photolithography.[10]
