this ancient method of painting uses pigments suspended in hot beeswax
Encaustic painting Encaustic painting, also known as hot wax painting, involves using heated beeswax to which colored pigments are added. The liquid or paste is then applied to a surface—usually prepared wood, though canvas and other materials are often used. The simplest encaustic mixture can be made from adding pigments to beeswax, but there are several other recipes that can be used—some containing other types of waxes, damar resin, linseed oil, or other ingredients. Pure, powdered pigments can be used, though some mixtures use oil paints or other forms of pigment.[1]
Durga Puja The traditional idols, states Christopher Chapple, are made of biodegradable materials such as "straw, clay, resin, and wood".[81] In the contemporary era, brighter colored statues have increased and diversified the use of non-biodegradable, cheaper or more colorful substitute synthetic raw materials. Environmental activists have raised concerns about the paint used to produce the statue, stating that the heavy metals in these paints pollute rivers when the statues are immersed at the end of the Durga festival.[81]
