The Eugene Holtier Violin Varnish System is comprised of Gold Color Wood Primer; Reflective Rosin Ground; Brown, and Clear Varnish; and if needed - a catalyst. The Gold Color Wood Primer and Reflective Rosin Ground are a way to prepare and treat the wood of a musical instrument prior to coats of varnish. The more attractive this layer, the more effective any varnish will be in enhancing the natural beauty of the wood. The Reflective Rosin Ground is a clear liquid which has very low viscosity and brushes easily. Eugene Holtier Varnish, made from finest colophony and cold pressed linseed oil (50-50 by weight), is rich in color and transparent. This varnish contains no solvents, catalysts or pigments. It is extremely transparent yet rich in color. The varnish is medium thick but can be easily spread and is not tacky. The brown color is very intense and only a few coats are needed for a rich color. The clear varnish can be mixed to change the intensity or can be used as a final coat. If desired, pigments or oil painting colors can be used with Eugene Holtier varnish. Drying requires UV and is only 3-4 hours in intense sun or overnight in the UV box. If you do not have strong UV box or strong sunlight, the catalyst may be needed to help cure the varnish. The varnish is available in brown and clear in 50ml bottles. One bottle will varnish 4-5 violins or 1 cello. Click on Specifications below for instructions.
