Topic: Apsley Pellatt Patent Specification December 18,1819 for incrusting figures

[flying free]

I couldn't see this on the board anywhere. It's a description of the 3 methods Apsley Pellatt patented for incrusting figures into glass.
Patent specification December 18, 1819.

Method number 2 - the second method he describes seems remarkably shocking to me - see page 68 (on fourth image link) where he describes the workman sucking out the air in the sulphide incrusted glass??  I can't believe that happened and I think we've discussed this on the board elsewhere.

The three methods he was patenting apparently can be seen from page 65 onwards in (I've left these links in because I was struggling to find  a direct link on google):

The Repertory of Arts, Manufacture and Agriculture , Volume XLV second series, published 1824
