Resist

[5] Song dynasty Jizhou ware used paper cut-outs and leaves as resists or stencils under glaze to create patterns.

[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.

This is the case when a resist is used to prepare the copper substrate for champlevé enamels, where parts of the field are etched (with acid or electrically) into hollows to be filled with powdered glass, which is then melted.

[11] In chemical milling, as many forms of industrial etching are called, the resist may be referred to as the "maskant",[12] and in many contexts the process may be known as masking.

[13] The Oxford English Dictionary does not record the word "resist" in this sense before the 1830s, when it was used in relation to both "calico-printing" (1836) and metalwork with copper (1839).

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