What is wax made of?

60g of rosin, 20g of insect film and 20g of artificial Venice turpentine. The production method is to put rosin and insect film into a disk or bronze ware (iron is not allowed to be used to prevent deterioration), heat it until it is completely melted, then slowly add artificial Venetian rosin, turn off the fire and let it coagulate by itself. If you want to color, wait until it is cooled to a suitable temperature, add pigment and stir it evenly, then pour it into the model to solidify it, and then take it out after it is completely consolidated. The coloring of wax paint can only be accomplished by adding oil-soluble pigments. Commonly used wax paint pigments are red and black, red is vermilion, and black is lamp coal. The amount of pigment is about 25% of wax.

1. Rosin: Rosin is an oil that permeates the trunk and bark of Pinaceae plants and other plants, and becomes a yellowish brittle block after drying. Its cracked surface has stripes, and its fragrance is quite like turpentine. Insoluble in water, but soluble in alcohol, ether, ketone and glacial acetic acid, it is transparent, but also soluble in chloroform, it is turbid. If it is ignited in the air, it can emit thick smoke. The melting point of rosin is soft and low, and it melts easily when the weather is a little hot. If the volatile turpentine contained in it is removed by distillation, a transparent amber crisp block can be obtained, which is the transparent rosin on the market. Rosin resin.

2. Insect membrane: A small insect on the Indian banyan tree pierces the gum flowing from the bark to protect itself. The insect film is a yellow-brown or reddish-brown transparent sheet, insoluble in water, soluble in hot alcohol, potassium hydroxide solution, sodium hydroxide solution and borax solution, and can be melted with a little heating.

3. Artificial Venetian turpentine: it is an artificial product, which is made by putting 62.5 parts of rosin and 22.5 parts of ramie oil into a pot, heating and melting with direct fire, and then quenching after melting, adding/kloc-0.5 parts of turpentine and constantly stirring.

4, vermilion is red mercury sulfide, lamp coal is soot.
