[QUOTE="Bronwen, post: 11899176, member: 5833"]That's a lot to digest. And I'm always interested in learning more, so would love to have the reference for information on changes in technology employed. As far as I know (& the technology has not been my main area of interest over the years so I may not know much) until the use of electricity became widespread, machinery for grinding & drilling was driven by foot power, the artisan pedaling or spinning a wheel with the feet, technologies that date back centuries. The use of corundum, & even diamond dust to provide abrasion also dates back centuries. In short, I do not believe that techniques for gem engraving changed very much over the 19th century, as I doubt the cameo-making industry would have been among the first to electrify. The tools for working shell are the same now as they were 150 years ago. I would attribute differences between individual pieces more to: [LIST] [*]Skill of the artisan [*]Preferred techniques of the artisan [*]Artistic standards & personal taste of the artisan; quality a piece needs to attain before the artisan is willing to put it on the market [*]Time available for making a piece [*]Financial pressure that may have dictated how much time could be spent on a single piece [*]Labor assistance, or lack thereof, in the form of apprentices [/LIST] I can think of other things, but these would have been major factors determining stylistic & technical differences. I don't think one can assume that all these things were equal among makers of a given time period or that technology available accounts for major differences. A major element that did change with time was demand from the buying public: the volume of work required to meet demand; the subjects & materials they wanted; the amount they were willing to pay. The use of a drill to deepen & round out curls is a technique (employing an ancient technology) I have noted in work of the later 19th/early 20th century. Subtle here, but I have seen Hercules with a head full of little drill holes to make his curly hair. [ATTACH=full]549833[/ATTACH] I think your piece is lovely, & may well have been a personal portrait of a lady styled to look like Ariadne or a maenad/bacchante. It was a popular thing to do. I could comfortably put her to the 1870s. Antonio Vergé appears to have been still active then, so not an impossibility, but I'm not convinced it's likely.[/QUOTE]
