Rosin Can Be Used To Make Fixed Painting Liquid

Due to the solubility, volatility, and the principle that rosin can quickly condense into a "strong and transparent film" after volatilization, painters usually make their own "fixed drawing" liquid to protect the picture and prevent "sketching" from being rubbed off. That is, one part of rosin powder, nine parts of alcohol, or a solvent ratio of xylene. First, place the rosin in a well sealed glass container, then pour alcohol or xylene into it, cover it, and dissolve it on their own after two days. When in use, shake well and pour into a spray can, 20 centimeters away from the screen. Spray evenly onto the screen, spray at any time, and evaporate at any time. After a few minutes, it will dry completely, and you won't be afraid of being rubbed off in the future. Attention: Rosin should not be excessive as it will turn yellow and dark.
