Notes about tumbler RD 70622, registered on24 July 1850 - Parcel 7 by George J. Green, Birmingham:
TNA's registration details summary reveals that the registrant's full name was George Joseph Green with an address at Broad Street, Birmingham. They also shows that Green registered another design for glass, ' a 'set of glass ware', RD 74749, on 21 July 1851, and that his address was 295 Broad Street, Birmingham.
It appears that 295 Broad Street, Birmingham, was the site of the Etna or Ζtna Glassworks, and there has been a longish thread on the GMB
https://www.glassmessages.com/index.php/topic,62885.msg353024.html#msg353024regarding the glassworks and some of its proprietors.
To 'summarise' it relevant to this thread:
Morgan Rollason & Co. were the proprietors of the Ζtna [sic.] Glassworks in at least 1837. By early 1839, Golds's patent Cut Glass Company were trading as glass- makers and glass cutters at Charlotte Street [?Birmingham or ?London} and the Ζtna Glassworks, Birmingham] as a partnership between John Gold[who, in 1834, had taken out a patent for a machine to cut broad flutes in glass], William Parker, Edward Parker, Nathan Kimberley, Samuel Shakespear, Theodore Moilliet, J. Hawker Gedford and James Geddes. This partnership was dissolved in March 1839,and John Gold who continued as sole proprietor of the glassworks. the Ζtna / Etna Glassworks then passed Joseph Green & Sons by 1842.
The firm of Joseph Green & Sons was a partnership between John Green (father) and his two sons, George Joseph and James. ) They traded at the Etna Glass Works; Birmingham, and at Upper Thames-street, London, as Glass Manufacturers and China Warehousemen. under the style or firm of Joseph Green and Sons, until the partnership was been dissolved, by mutual consent, as from the 31st day of December 1842.
George J. Green seems to have carried on as the sole proprietor of the Etna Glassworks until 1857, when he was declared bankrupt on 15 May 1857. His address was given as No. 3, York-road, Edgbaston, Birmingham, previously of the Harborne-road, in Birmingham.
There seems to be a gap in formation until Alfred Arculus took over the Etna Glassworks in 1860 and continued there until at least 1914.

https://birminghamhistory.co.uk/forum/index.php?threads/broad-st.30581/page-32indicates that the Ζtna Glassworks in Broad Street was shown as such on the 1890 OS map (see threads #635, 636 & 638).
Look along the extreme left hand margin, towards the bottom, to the left of 'Market Hall'. https://www.british-history.ac.uk/mapsheet.aspx?compid=55193&sheetid=10098&ox=325&oy=2031&zm=1&czm=1&x=5&y=25The whole area has since been heavily redeveloped and the site of 295 Broad Street is now completely altered.
