Presentation
Auscraft Ultra White plastic is available in 10 kilogram
plastic wrapped packs. The unfired colour of the clay is a yellow that
sets it apart from other white firing clays. The yellow is produced from an
organic stain which is completely removed during firing. Whatever your application Walker Ceramics can produce the
right consistency to meet your requirements.
