A method of engraving or ornamenting glass without cutting somehow?

The V&A say this of Davenport and their glass:

Quote
'Davenport is mostly known as a manufacturer of creamware and fine porcelain during the late 18th and early 19th century. In 1801, John Davenport entered a partnership with his old patron, Kinnersley and Edward Grafton of Stourbridge, to make high quality table glass at Longport, Stoke-on-Trent. The partnership finished in 1807 and the firm was continued by John Davenport and his cousin James as J. and J. Davenport. On 1st August 1806, John Davenport took out a patent for a special type of enamel decoration. This was a very complicated process that produced very fine, faint decorations inscribed into the enamel layer before firing. These were only produced for a few decades and almost all surviving examples are drinking glasses and this is one of only one or two jugs know to us. The most frequently occurring decorations show elegant country-sportsmen in contemporary dress. It is likely that such table wares were used to serve refreshments for country gentlemen who partook in such pursuits.

and the example they have in the museum:

and a pair of rinsers marked Patent on the base

and three more items including a goblet with a bust of Queen Victoria on it:

Edited to add - I don't think this was linked to Davenport.
A snippet I've managed to read seems to say that the glassworks at Longport was operated by Davenport, Kinnersley and Grafton and Kinnersley was a lawyer from Newcastle.  That partnership seems to have run from 1805 to 1807 and was dissolved in 1807 (22nd September 1807 London Gazette)



some information here on a glassworks called Grafton's Glassworks (not known if this relates to the Edward Grafton in my last post). It appears to have been called Coltman and Grafton.


It appears William Haden Richardson joined them sometime between 1802 and 1810.

In 1842 Wm. Davenport's Glass Manufactory,Longport  had 64 staff according to Aaron Maintford aged 32, Foreman, of which
'not more than 6 children' and '11 apprentices regularly bound by stamped indenture'.

According to Moses Lees aged 50, who paid the wages, there were about 1200-1400 staff across China,Earthenware and Glass of which a tiny proportion, 64 according to Mr Maintford,were in Glass section.

there is a gorgeous rummer showing in Timothy Mills book 'Rummers - A Social History Told In Glass' showing an example of his invention - pp. 48/49 - and detailing the method of Davenport's method of decorating glass.     In precis it was to do with covering the glass object in a glass paste - this was then scraped away to leave the desired pattern, then fired to fix the design.     Seems to have been too costly and time consuming to be commercially viable.        Assume m, that you do of course have a copy of Tim's book.

Yes I do.  Will take a look.  I knew about the method (read into it on querying the engraving on the Queen Vic uranium bowls)  but thanks for adding the info
