The wax encaustic painting technique was described by the Roman scholar Pliny the Elder in his Natural History from the 1st Century AD. [5] The oldest surviving encaustic panel paintings are the Romano-Egyptian Fayum mummy portraits from Egypt , around 100–300 AD, [ 6 ] but it was a very common technique in ancient Greek and Roman painting.

This wax resin is a better substitute to wax-resins because wax collects dust and dirt and make the fill noticeable. Polyester resin and epoxies are toxic and noxious. The wax-resin is fast and easy to use, making it a possible new alternative to fill materials in the conservation field.
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]
Self-cleaning surfaces are a class of materials with the inherent ability to remove any debris or bacteria from their surfaces in a variety of ways. The self-cleaning functionality of these surfaces are commonly inspired by natural phenomena observed in lotus leaves, gecko feet, and water striders to name a few.
Surface cleaning on encaustic paintings can typically be done with distilled water and swabs is sufficient. For more challenging cleanings, solutions made of beeswax and carbon tetrachloride can be used. One of the biggest challenges in treating encaustic paintings is identifying the different waxes used to determine the appropriate treatments.

Crayons are available in a range of prices, and are easy to ...
Another unusual method of cleaning frescoes is with the use of specific types of bacteria to remove inorganic crusts and animal glues from frescoes. Because bacteria can produce a whole host of enzymes they can deal with complex cleaning problems, metabolising organic and inorganic matter into hydrogen sulfide, molecular nitrogen or carbon dioxide.
