MIXTURE FOR STARCHING LINEN AND,SUCH LIKE."
"AN IMPROVED
The improved mixture is intended to be mixed and used in the proportion of
about one ounce to every three quarters of a pound of starch intended for use in
starching linen or clothes or other fabrics. The said mixture is made of the
following materials, or their chemical equivalents, in the proportions following, or
near thereto, viz.:-28 lb. sugar or saccharine matter, 84 lbs. borax, one quart
turpentine, one quart glycerine, one quart isinglass or gelatine solution (made one
ounce isinglass to the quart of water), one pint gum arabic solution or mucilage
(made one ounce gum to the pint of water), and one ounce essence of lavender.
The saccharine matter and the borax are to be first thoroughly incorporated by
mixing together and riddling through a sieve; the solutions are mixed all together
and sprayed into the above mixture by a brush or by other means.
The improved
nixture can be prepared and kept in a liquid state by boiling, or may he made and
kept in the form of a paste by mixing simply, or in the form of a powder by
allowing the water used to evaporate.

THOMAS LANCASTER, of Fulham, in the County of Middlesex. "AN IMPROVED
MIXTURE, FOR STARCHING LINEN AND SUCH LIKE."
The improved mixture is intended to be mixed and used in the proportion of
about one ounce to every three quarters of a pound of starch intended for use
in starching linen or clothes or other fabrics. The said mixture is made of the
following materials, or their chemical equivalents, in the proportions following, or
near thereto, viz.:-28 lbs. of sugar or saccharine matter, 84 lbs. of borax, one quart
of turpentine, one quart of glycerine, one quart of isinglass or of gelatine solution
(made one ounce of isinglass to the quart of water), one pint of gum arabic solution
or of mucilage (made one ounce of gum to the pint of water), and one ounce of
essence of lavender.
The saccharine matter and the borax are to be first thoroughly incorporated by
mixing together and riddling through a sieve; the solutions are mixed all together
and sprayed into the above mixture by a brush or by other means. The improved
mixture can be prepared and kept in a liquid state by boiling, or may be made and
kept in the form of a paste by mixing simply, or in the form of a powder by
allowing the water used to evaporate.
Subsequent experience has shown that a better result is obtained by varying the
composition of the mixture as follows, that is to say, by composing it of the following
ingredients in the proportions hereinafter stated:-
a. For a powder: 84 lbs. of sugar or saccharine matter, 56 lbs. of borax, 28 lbs.
of maize flour, 35 lbs. of carbonate of soda, 14 lbs. of rice flour, 21/2 lbs. of turpentine,
2 lbs. of glycerine, 1 ounce of oil of lavender.
b. For a liquid mixture: 12 lbs. of water, 4 lbs. of sugar, 3 lbs. of borax, 4 lbs. of
glycerine, 1 lbs. of turpentine, 1 lb. of rice flour, 1 ounce of oil of lavender, these
elements being simply mixed together and heated to boiling point.
The mixture (powdered or liquid) may either be combined with starch imme-
diately before it is used, or it may be well mixed with starch (preferably in the
proportion of one ounce of mixture to three quarters of a pound of starch), and the
compound thus obtained may be sold as an article of manufacture.
In witness whereof, I, the said Thomas Lancaster, have hereunto set my hand
and seal, this Second day of September, A.D. 1880.
