One of the techniques that can be done in encaustic is image transfer. This provides an opportunity for collage. One approach is to use xerox images, where the ink is transferred to the wax and the paper is removed.
Encaustic is often painted on hard board, but sometimes a white ground surface is desired for painting. There are various ways to get a white ground, in this example, watercolor paper is glued to the board.
Encaustic painters generally paint on hard surfaces. A common choice is wood; pre-manufactured boards are available, or you can build your own. Once you have a board, there are some simple steps to follow to prepare the board for painting.
When painting in encaustic you need medium. Encaustic medium affects the translucency of the colors you paint. Many artists like to make their own medium, which is a simple mixture of bees wax and damar resin.
