Improved Means or Method for Permanently Producing Markings,
Engravings, or Ornaments on Glass and Glazed Ware.
We, CHARLES GORDON PICKING, Engineer, of 2 Byron Villas, and CHARLES

of this invention to be as follows:-
60%
"
The object of this invention is certain means or method for permanently producing
markings, engravings, or ornaments on glass and glazed ware.
According to the present methods of marking glass and glazed ware, various
processes are adopted, such as 1. Hand or process printing and firing to fix the
prints. 2. Etching by acids. 3. Sand blasting processes more or less costly..
By our invention, we wet the material with water or other liquids and then
scratch or engrave the surface at the parts to be marked or ornamented by an
aluminium point, stick, or disc to any design required.
The depth of the engraving will more or less depend upon pressure but the most
delicate lines or markings can be cut, scratched, or engraved with very little skill
always, leaving a surface of aluminium upon the parts so scratched or engraved,
and in most cases without expensive machinery or appliances.
The glass so treated has all the appearance of having been ground or sand
blasted, and the parts so acted upon may be embellished by plain burnishing where
desired always leaving an aluminium coating of a silvery appearance upon the
parts so acted upon which can be easily coated with gold or other metals or
pigments, if desired.
