Created by layers of coloured glass in lime and fuschia, the transparent colours merge and create further hues throughout the piece. An additional optical illusion is also created as these are not solid pieces, hidden within, is a small, hallow interior space.
These require intense making from the initial blowing to create the amorphic form, through to the laborious cold work working and cutting, to literally slice a section of the piece away and then polish the revealed surface.
Inspired by the internal structures of naturally occurring geodes, it was during these investigations that Donaldson created a series of works influenced by the exploration of the 'vug', which is the internal space within a geode. A continuous theme to her work, the aim being, to draw the viewer into the internal movement of each unique piece.
