PROVISIONAL SPECIFICATION.
An Improved Enamel or Varnish for Rendering Casks and
Analogous Articles Damp Proof and for other Useful Purposes.
We EDWARD HIPWELL of New Hibernia Wharf Southwark in the County of
Surrey Provision Merchant and BENOIT BERNARD HOFMANN of the same place do
hereby declare the nature of said invention to be as follows:-—
The object of our invention is to manufacture an improved description of enamel or
varnish, for rendering casks and analogous articles damp proof, and for other useful
purposes. We manufacture our improved enamel in the condition of thick enamel,
and also of enamel wash.
In making thick enamel we dissolve one pound of white shellac in two pints of
alcohol (alcohol absolute). When perfectly dissolved we take one pound of the above
solution and mix the same thoroughly with half a pound of methylated spirit. We
then take one pound and a half of this mixture, and gradually add two pounds of Creta.
Gallica, continually stirring with a glass rod. We carefully prevent the tale forming
into lumps, and ensure the enamel being perfectly smooth and uniformly mixed.
In making thin enamel or enamel wash we boil one pound of ground rice in one
gallon of water for two hours, to form a thick mass. This is allowed to cool, and;
when tepid, one pound of gelatine is added.
We carefully mix the liquid and avoid burning; and add, when perfectly cold, a
quarter of a pound of salt. We then dissolve two pounds of Creta Gallica in one gallon
of pure water, and add, while continually stirring, half a gallon of the rice and gelatine
water.
.
When the mixture is quite smooth we add a quarter of a pint of methylated spirit,
mixed with a quarter of a pint of water, in which four ounces of gum arabic or isinglass
has been mixed. We stir thoroughly and fill into packages ready for use.
We apply the prepared material with a brush, using the thick enamel or the enamel
wash, according to the character of the material to which it may be applied:

We apply the prepared material with a brush, using the thick enamel or the enamel
wash, according to the character of the material to which it may be applied.
We do not confine ourselves to the exact proportions hereinbefore mentioned as they
may be varied to suit the purposes for which the enamel is required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The manufacture and use of the improved thick enamel substantially as and for
the purposes herein before described.
2. The manufacture and use of the improved thin enamel substantially as and for
the purposes hereinbefore described.
3. The application of the improved enamel for rendering casks & analogous
articles damp proof and for other useful purposes, substantially as hereinbefore described.
