Antique English or India Enamel on Copper Plate Unknown Mystery

I have these two dishes and I don't have a clue what they are used for. They appear to be some type of enamel on copper. I have searched all over the Internet and I can't find anything similar or what the are called or their purposes (other than decorative). Could anyone please help me out with some more information about these pieces; age, period, maker, country of origin, value, name of items, process used to make them, etc?

Thanks a bunch, all input is appreciated.
