Bentone: The whitest burning plasticizer we have seen


Wednesday 12th November 2014

Bentone (A.K.A. Macaloid MA) is a very plastic highly refined hectorite clay. This specimen has been mixed as a slurry, then dewatered until plastic on a plaster slab (it is very resistant to giving up its water). The plastic material has a very high water content, is exceptionally sticky and took many days to dry from the plastic stage. It shrinks 30% or more from plastic to fired and burns pure white at cone 6 (it can withstand higher temperatures). It burns whiter than similar materials from other manufacturers.
