I, LUDWIG BEECK, Manufacturer, 38, Prinz Ferdinandstrasse, Crefeld, Ger-
many, do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:
―
The object of the present invention is a process for manufacturing size-powder
to be used with great advantage in decorative painting. In decorating walls
and the like they must, previous to painting proper, have a coat of suitable
priming to make them fit to receive the colour and fix it.
A primary has been hitherto been used consisting of soap, alum and size and
to apply this the soap and alum have been dissolved in water and boiled size
has been mixed with them. This process is tedious and inconvenient and can
only be avoided by pulverising the materials with a view to simply dissolving
them on the spot. Pulverisation has hitherto been impossible inasmuch as
boiled size has always had to be used and this cannot on account of its high
elasticity and adhesive nature be reduced to powder by simple means.
The process which is based on the present invention, enables size to be
pulverized by first steeping it in the ordinary way and then thoroughly boiling
it. While this perfectly fluid boiling hot solution of size is being poured out,
calcined soda or alum or any other salt, which by its nature has a similar effect,
is added in such proportions say equal to about 150 to 180% of the glue that
a dry mass results from the whole. Soda or alum takes up the water of crystalli-
sation contained in the size and brings about a complete solidification of the
mass, so that it can be easily pulverised, the taking up of the water of crystalli-
sation by the soda or alum producing complete crystallisation. The size powder
obtained receives an addition of the requisite quantities of soap and alum accord-
ing to the judgement of the painter for making priming and the manufacture
of the priming powder is complete. For example it is only necessary for the
painter to take a tablespoonful of the powder and dissolve it in a litre of warm
water to obtain an equal quantity of priming. When the powder is dissolved
in warm water the size contained in it regains its original adhesive qualities
and elasticity.
It is therefore a new and special discovery that a priming hitherto used in
liquid form only can, on the score of utility be manufactured in the form of a
powder, and that size can be temporarily deprived of its elasticity and adhesive
qualities.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
CLAIM.
A process for manufacturing priming-powder characterised by a solution of
size made in the ordinary way by steeping and boiling size, receiving such an
addition of soda, alum or some salt, which by reason of its nature has the same
effect. that an almost dry mass results which, when fully solidified can be

increased solubility of the size occasioned by its finely divided state.
