Rana Rochat paints with encaustics, which are experiencing an explosion in popularity (although it is a very difficult medium to master). Encaustic art is created with a mix of oil pigment and hot liquid wax. The wax is applied to a firm surface then reheated by a heat gun or blow torch to fuse the paint and wax together. It is an ancient art technique; 3000 year old examples of encaustic art exist, in original Egyptian wax portraits.
The results of painting with wax are beautiful....encaustic pieces attain a layered, transparent look that is like no other art medium. They are quite durable; people often worry that encaustic pieces will melt, but they are stable until a temperature of 140 degrees. If your house is 140 degrees, you have other problems to worry about! It is best not to put an encaustics piece in direct sunlight, but this is true of all paintings.
