Suacer with cup not sure who made this

Ok, that is a teabowl and saucer. The flower is sometimes called Adam's rose and the decorative technique is spongeware (you'll see some as spatterware). It's 19th C probably English and not sure that you'll be able to find a maker unless it's marked.

 

It may be even earlier than that, and it may also be Scottish. A lot of spongeware was made there.

 

I know this is focused on artifacts found in the US but it does give a guide to some shapes, material and decorating types of Staffordshire cups. I'd guess this is a version of what they are calling double curve shape in a whiteware body with sponge decoration. They'd date it 1830-50 or so.

It's quite lovely!!!

 

I'm fascinated by the fact that two hundred year, or more, old things have designs that look modern.
