PROVISIONAL SPECIFICATION.
Improved Ink.
I, EDWIN HENRY TEMPLE, of 92 Victoria Park Road, South Hackney, in the
County of London, Gentleman, do hereby declare the nature of this invention to be
as follows:-
..: My invention has for its object an ink which will not permanently stain wearing
apparel or other fabric or fibrous material when inadvertently spilled thereon, but
may be removed by washing in the usual way.
With this object. I employ a saline base for the ink, and having added thereto
suitable quantities of logwood, Turkey nut galls, gum arabic, and sulphate of iron, or
other suitable ingredients, brew the whole until it has attained the desired appearance
and properties.
The proportion and nature of the ingredients may be varied as required but the
following. I find yields a good black ink.
:
Take of water slightly impregnated with common salt one gallon, and add thereto
lb. logwood, 1 lb. finest Turkey nut galls, lb. gum arabic, 2 oz. sulphate of iron.
This mixture is then allowed to simmer for a sufficiently long period to enable the
ingredients to yield their usual properties, and is then strained off and cooled, when it
is ready for use.
The saline base prevents the ink becoming a fast dye, and so permits of its being
removed by the ordinary process of washing of any garment or other article stained
by it.
