[A communication to him from abroad by J Hautrive of Lille, in the Republic
of France]
After having received a coat of mordant mixed with white lead the cloth &c. to
be metallized is powdered with particles of lead, and when the layer is dry the
lead is rolled upon the cloth so as to obtain a homogeneous layer. This application
of metal can be made to all objects that will bear rolling. The same means are
used when the surface is not plane, but in this case burnishing is employed
instead of rolling. Any malleable metal reduced to small particles may be used
for metallizing. The metal particles required for metallizing cloth or other articles
as desired, may be obtained by rasping.
Plumbago, being a carbon, does not absorb moisture and is a bad conductor of
heat its application consequently prevents the decomposition of bodies to which it
is applied
It is fixed by means of a mordant or varnish and is applied to the cloth
metallized by the above process of "artificial galvanization to impart greater

page_text: durability to such products for use as a covering for buildings, sheds, railway
vehicles tramcare, steamers &c.
It may be employed with great advantage upon tarpaulins to prevent the fatty
matters with which these are coated to make the cloth waterproof, being absorbed
by the sun.
It is also applicable to cardboard for making roofing material, to packing paper,
to damp walls to rolled or other metals, to tubes of all kinds to preserve them from
oxidation, to wood &c
After application and when the layer is sufficiently dry it may be burnished by
friction. As this layer of carbon is proof against acids, articles treated there with
will be particularly adapted for use in seaports.

A communication to him from abroad by J. Hautrive, of Lille, in the republic
of France
After having received a coat of mordant mixed with white lead the cloth &c to
be metallized is powdered with particles of lead and when the layer is dry the
lead is rolled upon the cloth so as to obtain a homogenous layer. This application
of metal can be made to all objects that will bear rolling. The same means are

instead of rolling. Any malleable metal reduced to small particles may be used

Plumbago being a carbon does not absorb moisture and it is a bad conductor of
heat its application consequently prevents the decomposition of bodies to which it
is applied.
It is fixed by means of a mordant or varnish, and is applied to the cloth
inetallized by the above process of "artificial galvanisation to impart greater
durability to such products for use as a covering for buildings, sheds, railway
vehicles, tramcars, steamers &c.
It may be employed with great advantage upon tarpaulins to prevent the fatty
matters with which these are coated to make the cloth waterproof being absorbed
by the sun.
It is also applicable to cardboard for making roofing material, to. packing paper,
to damp walls to rolled or other metals to tubes of all kinds to preserve them from
oxidation, to wood, &c.
After application and when the layer is sufficiently dry it may be burnished by
friction.
As this layer of carbon is proof against acids, articles treated therewith will be
particularly adapted for use in sea-ports.
Having now described the said invention as communicated to me by my foreign
correspondent I wish it to be understood that what I claim and desire to protect
under the bereinbefore in part recited Letters Patent is :
The metallization of roofing and other cloth or articles substantially as above
described
In witness whereof I the said Alfred Julius Boult have hereunto set iny
hand and seal this twenty sixth day of January in the year of Our Lord
One thousand eight hundred and eighty three.
