FREDRIK SUNDT, of Christiania, in the Kingdom of Norway, Merchant. "A NEW
WATERPROOF MATERIAL TO BE USED IN THE DECORATION OF BUILDINGS AND
OTHER ORNAMENTAL PURPOSES."
The improvement consists in the use of wood reduced to a state of pulp, and
when sufficiently plastic the following chemicals are mixed therewith to render the
material waterproof and binding:
(1.) Sulphate, acetate, or any other kind of alumina.
(2.) Any resinous or fatty substances saponified.
(3.) Chromate or bichromate of potash.'
(4.) Glue, lime, blood, or casein, according to purpose.
The material is then compressed into moulds by means of hydraulic or other
power for the purpose of forming articles to be applied in the decoration of buildings
and other ornamental uses.
The articles when manufactured are waterproof, and in this consists one of the
leading features of the Invention. They can be tinted to any desired color during
the process of formation, or after they are manufactured.
