Here I show you two little brooches and a stickpin. Very nice but please have you any idea how to see the difference between French yet (black glass) and real yet? There is also Vulcanite but this has always a black brownish color and these three are real black. I know one of those differences is the temperature because glass always feel cold and perhaps a difference in weight?
These three are about the same width.; bow-shaped 5.5 cm, middle one 4.5 cm and the stickpin also 4,5 cm. The weight of the bow-shaped brooch is 6 grams, the middle brooch on the photograp is 5 grams and the stickpin only 3 grams. I must add that the bow-shoped brooch seems to be a little duller black than the other two.
Again my question: what period please and what kind of material?
