Talking to a peer in ceramics, they have advised the best finishes for my forms would be to apply a shop bought underglaze to the surface using a brush, this has benefits as it allows me to undergo the process faster, as well as guaranteeing a good finish. The pigments in the mixed glazes are also brighter.
I am keen on the pink green and grey underglazes, one applied and fired these will be matte, this is an interesting option for me as it will compliment the juxtaposition in my work and should make the forms stand out form one another considering the plaster is polished. furthermore if i where to decide I wanted them to have a sheen I could apply a transparent glaze to the surface.
