Lamour Charbonnel Lefranc and Bourgeois black protective varnish 250ml

• Lamour black protective varnish is a liquid varnish specifically designed to protect the back and edges of the etching plate during the acid etching process.
• It is specially formulated to be extremely acid resistant. Its main function is to protect the areas on the back and edges of the plate that are not to be etched from the corrosive effect of the acid used in techniques such as aquatint.
• When properly applied, it creates a protective barrier that preserves the unwanted areas of the plate during the etching process.
• To apply the protective varnish, it is important to ensure that the plate is thoroughly degreased and cooled. It is recommended to use a flexible brush for best results during application.
• It contains asphalt and turpentine, which are the main components of its composition. The dry extract of the varnish is 25%.
• It leaves a glossy, opaque finish on the surface of the protected plate. This helps to clearly identify the areas covered during the engraving process.
