Charlotte Roden, a stained-glass student at the University of York, is appealing for information regarding the cameo glass technique developed at the end of the 19th century in Glasgow by Meikle and Sons but was surely experimented with by other studios around this time. She is focusing on the process / technique used to create details on glass which look like glass paint but in fact have been made using hydrofluoric acid to etch the glass and then layer pieces of glass to achieve the desired effect.
Around 1900, many glass studios were experimenting with acid etching and the Cameo glass technique was only one of many effects discovered by artists at this time. If any Vidimus readers are able to offer any anecdotal information about such glass or are aware of windows using this technique, please contact Charlotte Roden directly at firstname.lastname@example.org. Thank you!
