Paraffin wax (or petroleum wax) is a soft colourless solid derived from petroleum, coal or shale oil that consists of a mixture of hydrocarbons molecules containing between twenty and forty carbon atoms.
It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), and its boiling point is above 370 °C (698 °F).
Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons
