Gum rosin (colophony) is a type of resin that is typically obtained from conical plants. California is mostly semi-transparent and has yellow to black rosettes.
It is solid and brittle at room temperature but melts at the stove temperature. colophony is soluble in alcohol, ether, benzene and chloroform and is often used in the process of soap making. Other uses include resin for making violin lacquers, waxes and adhesives, oil paint production, as well as studio and stage floors (to prevent slippage).
Another use of Colophony is its use in the printing industry as a color carrier, which results in greater adhesion of color when printing.
Prolonged exposure to smoke caused by solder with calcium can cause occupational asthma.
Long-term skin contact with this substance can also cause a skin condition called industrial contact dermatitis.
