BakeliteUse 409 bathroom cleaner on a cotton swab and I rub it on the back side of the item if it turns yellow I know that it's Bakelite. Black Bakelite doesn't always turn yellow. Put the item under a stream of hot water and it should have an odor that smells like varnish or formaldehyde. Mosaic
Mosaic. This type of Mosaic was probably made in Florence and is known as a pietra dura. They were made of small pieces of stone such as such as malachite, lapis lazuli, coral, opal and others skillfully arranged into a black background, usually of marble. They were usually made in a floral design and became miniature works of art. Mosaics of superior quality were mounted in solid gold frames; sometimes pinchbeck and sterling silver. Mosaics were popular in England between 1820 and 1860. They are produced in Italy today for tourists. Your picture looks like its an antique. These are rare and highly collectible. We have a similar piece on our website http://antique-vintage-costume-jewelry.com/antique_jewelry/an1028.htm they are hard to find. Your have an exceptional silver work with lots of great detail that was made for the Mosaic PearlCultured and natural pearls feel gritty or slightly sandy rough when you rub it gently across the outside of your front teeth. Pearls improperly cleaned will lose the gritty feeling and fell smooth same as fake pearls. Tortoise ShellWhen I first look at a piece of Tortoise Shell I will feel for a wavier finish. Then I will look with a 10X loop where the light color changes to the dark area and is made of small dark dots. You can also touch the piece with a hot needle and it will emit the strong odor of burning hair. If you look at some of our items at http://antique-vintage-costume-jewelry.com/vintage_costume_jewelry/tortoise_horn/tortoise-shell-horn-page1.htm I hope it adds to you understanding. |
