Small Pottery vase - Alison Borthwick

This one puzzles me a bit, the decoration looks really good, you can see the tiny crystals when looking through magnifying glass. It is translucent so I guess it's porcelain, possibly moulded as the seam is visible on both sides. 5 1/4'' tall .
The signature isn't in my books I'm afraid. Any ideas?

Alison Borthwick, I believe. Almost bought one of hers. Lovely decoration.

Is the decoration done by impressing a mesh in the surface of the clay?

Thanks Naomi, I have found a few pieces at Robert Gordon University website: http://www.rgu.ac.uk/about/art-and-heritage-collections-/exhibition-archive-gallery/hidden-treasures.
The decoration is done by impressing the mesh I think studio-pots, unless it's done in specially prepared mould? The mesh would have to be coated with oxides or other chemicals that create that colours and crystals.

Thanks, Red.
