page_text: LETTERS PATENT to Alfred Tooth, of Number 14, Mincing Lane, in the
City of London, Merchant, for the Invention of "AN IMPROVED PROCESS
FOR BLEACHING MALT, WHEREBY THE COLOR IS RENDERED MORE SUITABLE FOR
THE BREWING OF PALE OR BRIGHT MALT LIQUORE."
Sealed the 14th April 1857, and dated the 16th October 1856.
PROVISIONAL SPECIFICATION left by the said Alfred Tooth at the
Office of the Commissioners of Patents, with his Petition, on the 16th
October 1856.
I, ALFRED TOOTH, of Number 14, Mincing Lane, in the City of London,
Merchant, do hereby declare the nature of the said Invention for "AN
IMPROVED PROCESS FOR BLEACHING MALT, WHEREBY THE COLOUR IS RENDERED
MORE SUITABLE FOR THE BREWING OF PALE OR BRIGHT MALT LIQUORS," to be as
follows:-
My Invention consists in the employment of sulphur for the purpose of
bleaching malt, which I find perfectly effects that object, improving the malt
both in taste and quality. My mode of applying the sulphur is as follows:-
So soon as the malt is placed in the drying chamber I place within it a
suitable iron vessel containing the sulphur, in the proportion of one ounce of
sulphur to a quarter of malt; I then burn the sulphur by making the iron

ing the malt thereby a very pale bright color; the suphur may be repeated if
necessary.
I do not confine myself to the quantity of sulphur mentioned as necessary,
or the mode by which it is introduced, but claim the use of sulphur in bleaching
malt.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Tooth in the Great Seal Patent Office on the
14th April 1857.
