PROVISIONAL SPECIFICATION.
A New or Improved Blotter.
I JOHN NASH of No. 1 Taylor Street Weaste Salford in the County of
Lancaster Manager do hereby declare the nature of this invention to be as
follows:-
My invention has for its object the production of an improved porous earthen-
ware substance of a highly absorbent nature which render the material a valuable
substitute for blotting paper for absorbing ink or other liquids from writing paper
books and the like.
According to my invention I make a slab or tile of porous earthenware or
porous terra cotta of any suitable size and thickness I apply the slab or tile to
freshly written matter in the same way as ordinary blotting paper is applied the
effect is to absorb the superfluous ink leaving the writing clear and legible.
I do not confine my invention to flat surfaces as I sometimes prefer to make the
blotter in the form of a roller or with curved surfaces.
Should the blotter become corroded I heat the same in a fire to a red heat and
allow it to cool.
Blotters made in the manner described will be found to be extremely durable
being practically indestructible.

COMPLETE SPECIFICATION.
A New or Improved Blotter.
I JOHN NASH of No. 1 Taylor Street, Weaste, Manchester, in the County of
Lancaster, Manager, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement that is to say :-
My said invention relates to a new or improved blotter to be used as a substitute
for blotting paper. According to my invention I make a slab, tile, roller or other
suitably shaped body from porous ware which will act as an ink or liquid absorbent.
The material from which I make my improved blotter is not strictly speaking a
new material as so called porous tiles and bricks are well known in the market.
But in compounding the material from which I make my blotting appliance I take
a proportion of white red or other suitable clay and mix with it about an equal
proportion of fine sawdust. When thoroughly amalgamated the slabs or other
bodies comprising my improved blotters are fashioned therefrom and are then dried
and burned or the material might be fired in larger masses and the slabs or blotters
afterwards sawn or otherwise formed from these larger pieces of material.
not however confine myself to fine sawdust for mixing with the clay as peat dust,
pounded shale or other similar vegetable or combustible material might be used.
The proportions of vegetable or combustible matter added to the clay might be
varied according to the nature of the clay and in some instances where the clay
holds a sufficiently large per-centage of vegetable or combustible matter in itself
no addition of the said ingredients would be necessary.
I do
The blotters made from the aforesaid material may be of various shapes and
sizes. For example I might make them in the form of slabs either flat or slightly
rounded on the face or I might make them with a "hog-back" or curved face and
either with or without handles. I might also make my improved blotters in the

page_text: form of rollers preferably carried in a frame with a handle. When from long
continued use the face of the improved blotter becomes charged or choked with
ink its efficiency can be restored by heating it in a fire to a red heat and allowing
it to cool.
My improved blotters are therefore cheap durable and practically indestructable 5
except by violence.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improved blotter formed from porous earthenware substantially as herein-
before described.
