The wonders of wax

"Festival of Flags I'' (encaustic), by Jeanne Griffin, in the big group show "Beneath the Surface,'' at the Saco Museum, Saco, Maine, April 2-May 28.

The show includes the work of some of New England's best painters working in encaustic, also known as hot-wax painting. The process involves using a mix of heated beeswax and damar varnish to which colored pigments are added. The liquid or paste is then applied to a surface -- often prepared wood, although canvas and other materials are often used. The effects can be very beautiful --- and sometimes eerie.
