Hand rolled beaker & a jug, stamped Jess - Jessica Ball

Two porcelain pieces by the same potter, one hand rolled, both with applied beads.
The impressed mark is very small, but with such a distinctive style I am hoping it is an obvious one for someone.
Very recent in age, I believe.
The potter is possibly from York.
Any help appreciated.

And the beaker...

If you rotate it, I'm clearly seeing "Jess".

Thanks very much denby that gives me something more to go on, greatly appreciated.
All I was seeing was an O, which is not there at all. My eyes are dreadful

Possibly Jessica Joslin, though yet to confirm.
Whether it's one of her own, or a "paint your own piece" from her pottery workshop, I do not yet know. I'll update this if and when I get to the bottom of it
Thanks again Denby
