Kisameet Glacial Clay

The Kisameet story began centuries ago when the mineral clay was first discovered by the Heiltsuk people. Natural elements of such purity, smooth texture, and vibrant colour are still rare today, so we can imagine that this blue-green mineral may have been precious to the people inhabiting the rugged central coast 10,000 years ago.

Necessity is the mother of invention and, like so many other discoveries and developments by the Heiltsuk people, the use of the mineral clay for healing is well documented, as it is in many cases for indigenous populations around the globe.

Dr. E. H. Hauser’s Analysis

It’s reported that in the 1930s a sample of the mineral clay from Kisameet Bay was given to a commercial fisherman and later ended up at MIT. A well-known colloid scientist, Dr. Ernst Hauser studied it and compared it to many other known clays. In his Paper, The Kisameet Bay Clay Deposit, he summarizes his analysis:

“On the basis of x-ray diffraction studies, ultra-microscopy by incident light, electron microscopy and systematic studies of such colloidal phenomena as electrophoresis, thixotropy, dilatancy and film formation it is concluded that the Kisameet Bay Clay deposit is an aluminum silicate which differs from all other known clay minerals not only in its composition but also in it’s properties.”
