Here is an enamelled brass button with a bright purple background and one small white flower in the middle. The fancy gold border just sets it off nicely. It is not a very big button at a little over 1 1/2cm.

Here are two lacy glass buttons which are not easy to get in really good order. Sometimes the paint is quite rubbed on the back. They are clear moulded glass with the colours painted on the back and then a coating of black or silver. The colours show through to the front. They are very expensive if in good order. These ones measure 3 cm and have a metal shank.
I think this plastic button might actually be Casein but am not sure. I do not know all the different plastics so just generalize. This round button has been dyed red and then carved away in a star like design to reveal the cream colour underneath. That is my theory anyway and stand to be corrected.
