An extremely white firing delaminated material of low plasticity. Kaopaque 20 is a non-predispersed, delaminated kaolin produced from a water-fractionated feed for a controlled particle size and shape. It has very large plate-like particles. It is useful in casting porcelains. It is refined from Geogia deposits.

Kaopaque 10S is the pre-dispersed version of Kaopaaque 10 and is supplied as a lightly pulverized spray-dried powder and as a slurry. Kaopaque 10S is a delaminated kaolin with a controlled particle size distribution.
Kaopaque 10 is a non-predispersed, delaminated kaolin produced from a water fractionated feed for a controlled particle size and shape. The large plate-like particles of Kaopaque 10 have a thickness of 0.2 to 0.4 microns and a diameter of 2 to 10 microns.
