Hi solavirtus - the mark on your small vase is that made by Margaret Shotton (1937-). "From 1965-67 Domestic & functional stoneware. 1979 - Thrown decorative oxidised stoneware & porcelain. Carved & applied decoration. Crystalline & other glazes. Also from 1997 - Modelled British fungi species, in porcelain & stoneware." British Studio Potters' Marks (Yates-Owen & Fournier) p.455. Judging by the style of yours, I would guess yours dates from 1997.
Hi Stephanie & welcome

It would be a good idea to post your request on a new posting so that peeps will see it, rather than here, and a picture always helps.
