Synthetic painting, that is, comprehensive material painting, is used to define those paintings with non-traditional materials in modern painting.
For example, newspapers, sacks, and metal are pasted on the screen, and then painted with paint. There are also some paintings that combine painting techniques and installation techniques but are more static paintings. There are many and it is difficult to generalize.
There is no established tradition or system, and it is mostly improvised. It is difficult to find a more authoritative and comprehensive discussion.

Materials for mixed-material painting:
Emulsion. It is a mixture containing oil and water. It is used for color mixing. It can be smoothly blended with oil paints, increase its thickness, and dry faster than using oil alone. Especially the color layer solidifies quickly. A good emulsion can be used for color mixing. The layers completely set in two minutes and can be covered with new layers of color to create thick textures, a method used by Rembrandt.
However, there are many formulas and production methods for lotion. Rembrandt's one has been lost, and future generations have not yet figured out the reason.
A book "Research on Painting Materials" was published in China in the 1990s. It was written by Pang Tao, which she learned from Bincas in the technique studio of the Academy of Fine Arts in Paris, France. How to make Cass Lotion.
After all, water and oil are insoluble in each other. They have different specific gravity and tension. To mix them into emulsions, the production techniques must be very particular.
One of the ingredients in Bincas lotion is methylcellulose, also called cellulose methyl ether.
