An Improved Varnish, specially applicable for Giving a Frosted
Appearance to Glass, Talc, or the like.
We, MESSRS. BLUNDELL, SPENCE & Co., LIMITED, Beverley Road Works,
Paint, Colour and Varnish Manufacturers, and SYDNEY HILL, 11, Salisbury
Gardens, both in Hull, in the County of Yorkshire, Analytical Chemist, do
hereby declare the nature of this invention to be as follows:-
The object of our invention is to produce a varnish, which though clear and
transparent when applied, becomes semi-opaque or crystaline en drying, and
when applied to glass tale or other transparent material or substance, produces
the appearance of ground or frosted glass or the like; such varnish can also
be used for covering or varnishing paint, for the purpose of giving it a crystaline
instead of a polished finish.
For the purpose of our invention, we employ a pale copal varnish, in this, by
steam, heat or other means, we dissolve resinates and stearates of lime, lead, and
manganese, and to this preparation we add tung oil, also on cooling we add
a small quantity of essential oil or oils for the purpose of increasing the solubility
of the stearates in the cold varnish and of improving the crystaline appearance
of the surface when such varnish has dried.
The above ingredients when mixed together in suitable proportions produce
a varnish with the beforementioned qualities.
