An Improved Glass-cleaning Mixture.
I, JAMES HENRY BALLIN, of 52, Threadneedle Street, at London, E.C., Bank
Clerk, do hereby declare the nature of this invention to be as follows:-
This invention relates to means for cleaning and polishing windows, mirrors
and the like, and especially preserves these objects from steaming and freezing
without impairing their brilliancy or brightness.
The mixture, which is of a saponaceous nature, is supplied to the public in a
semi-solid form and sold in small boxes or otherwise, and commonly called in
the trade "Crystalline."
It only requires to be used on the windows, mirrors and the like, a small quan-
tity being applied with a piece of flannel or sponge.
I preferably rub some of the mixture upon the glass of either window-pane or
mirror and wipe it with a dry clean rag or cloth. A first treatment will hold good for
say three or four days, and after three such applications, the effect will last a week
or more.
The mixture, which may vary somewhat as regards proportions, contains the
following substances, generally in the proportion of:
1 quart of water,
2 lbs. of light colored unscented glycerine soap, or another unscented soap,
lb. powdered white sugar,
½ ounce of cumarin, and
8
A pinch of powdered aniline-dye.
I prefer to add first the glycerine soap to the water, boiling the mixture till
dissolved; then I add the sugar, the cumarin and the aniline. This mixture must
be stirred until it is colored by the dye; I then skim off all impurities, and after
allowing it to cool, I pack it in vessels, boxes or the like.

I prefer to add first the glycerine-soap to the water, boiling the mixture until
dissolved, and then I add the sugar cumarin and aniline. This mixture must be
stirred until it is coloured by the dye. I then skim off all impurities, and after
allowing it to cool, I pack it in barrels, boxes and the like.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A glass-cleaning mixture, containing water, unscented soap, powdered white
sugar and a small quantity of cumarin.
2. A glass-cleaning mixture according to the first claim, containing the said
