I am a button nut. As you can see from the picture above, I have an addiction to Victorian black glass buttons. I probably take a half hour each day to search through the eBay and Etsy. My favorite search words is "black lacy glass buttons" Why black glass? In the late part of the 19th century the most detailed buttons were comprised of black glass. These black glass buttons are also called mourning buttons, this is due to the fact that Queen Victoria wore only black jet buttons after the death of Prince Albert. Another favorite search word of late is "carved celluloid". Bakelite or celluloid was the first plastic of the 20th century. It was not until the I came across this celluloid bird shown below, that I paid more attention to carved celluloid.

Below is an example of my Sunflowers Pendant, you can see the finished silver pendant, the unfired greenware, the original black glass button and the two part silicone mold.
