Two plasticizers show vastly different potency

Tuesday 2nd August 2011

A comparison of the insight-live.com/glossary/143">plasticity of two bentonites was done by diluting them with silica. The top sample is Volcay 325 mixed 25:75 with silica. It is a standard Wyoming sodium bentonite - mined, dried and ground. The bottom specimen is Hectalite 200, a highly refined white hectorite, mixed 50:50 with silica. Notice how much less plastic it is (even though at double the percentage).
