Similarly, how long do you leave etching cream on glass?
For a more pronounced etching, use your brush to move the cream on top of your stencil. At about the 1 ½ minute and 3 ½ minute marks, do this to break up air pockets that will cause uneven etching. Leave the cream for five minutes. Overall, including stirring, the cream needs to stay on the glass at least five minutes.
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In traditional pure etching, a metal (usually copper, zinc or steel) plate is covered with a waxy ground which is resistant to acid.
