Encaustic is a painting technique whose origins date back to the first century AD, a time in which it was widely used among the ancient Greeks and Romans. Over the centuries it was gradually abandoned due to its complexity. Encaustic came back into fashion only at the beginning of the 20th century, arousing the interest of numerous artists thanks to the advent of electricity. The main difficulty of encaustic painting, in fact, is the need to have continuous sources of radiated and direct heat available. Originally obtained through the use of braziers, today it is possible to obtain the necessary heat using electric plates and gas torches. The encaustic practiced by contemporary artists is therefore defined as "modern". However, the modernization of the technique has not diminished its artisanal character, the use of natural materials and substances remaining necessary. Encaustic paintings are particularly resistant and durable works of art, just think that some paintings from the 1st century have come down to us. AD performed with the same technique.

Encaustic paintings do not require protection, such as glass or plexiglass. Thanks to the presence of natural resin in the binder, the surface of these works becomes increasingly resistant as time passes, making them resistant to insects, humidity and atmospheric agents. The only care they require is an occasional polishing performed by passing a very soft and dry cloth over the surface of the painting.
