PROVISIONAL SPECIFICATION.
New or Improved Composition for Varnishing or Polishing. :
I, JOHN STEWART MACARTHUR of the Firm of Blacklock & Macarthur, Paint,
Colour and Varnish Manufacturers, West Street, Tradeston in the City of Glasgow,
do hereby declare the nature of this invention to be as follows:-
This invention consists in a new or improved composition designed for varnishing
or polishing wood or metal work, paper and other substances and especially
applicable for polishing chip hats or bonnets.
The improved varnish or polish is composed of shellac or other gums or of
shellac and other gums dissolved in methylated spirit and to which is added a small
proportion of castor oil with the object of keeping the composition soft. A small
proportion of Venice turpentine may also be added. An analine dye soluble in
spirit is or may be added to colour the composition to any tint desired.
I do not confine myself to any precise proportions of the ingredients but I find
the following to be suitable :
New of proved Composition for varnishing or Polishing.
1, JOHN STEWART MACARTHUR, of the Firm of Blacklock & Macarthur, Paint,
Colour and Varnish Manufacturers, West Street, Tradeston, in the City of Glasgow,
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:―
This invention consists in a new or improved composition designed for varnishing
or polishing wood or metal work, paper and other substances and especially
applicable for polishing chip hats or bonnets.
The improved varnish or polish is composed of shellac or other gums or of
shellac and other gums dissolved in methylated spirit and to which is added a small
proportion of castor oil with the object of keeping the composition soft and elastic.
The composition thus contains the ordinary ingredients of a spirit varnish with
the addition of castor oil, the proportion of which while largely varying will usually
average from 5 to 10 per cent. of the composition. A small proportion of Venice
turpentine may also be added. An aniline dye or pigment soluble in spirit is or
may be added to colour the composition to any tint desired. The gums used

page_text: along with or instead of shellac may be copal, gum arabic, gum sandrac, gum animi,
gum dextrine, gum elemi, gum juniper.
When other gums are used in substitution for shellac or along with shellac the
total quantity of gummy matter employed may be practically the same as if shellac
alone were used, the proportion of the gummy ingredient and of the castor oil
being however dependent largely on the consistency of the composition desired.
I do not confine myself to any precise proportions of the ingredients but I find
the following to be suitable for the production of a soft polishing composition.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The new or improved composition herein described for varnishing or polishing.
Dated this 21st day of November 1894.
