spirit varnish การใช้

• Quick-drying enamels are spirit varnishes ground with the desired pigment.
• The finish produced by spirit varnishes was transparent but brittle and susceptible to water damage.
• Lacquers or spirit varnishes are made from very soft gums, such as shellac and sandarach, dissolved in methylated spirit.
• Before the development of modern oil varnishes, spirit varnishes using shellac, damar or mastic resins dissolved in alcohol were popular.
• Today oil varnishes have replaced all spirit varnishes with the exception of shellac ( See the Home Clinic, Oct . 22 1995 ).
