Eckalite 1, 2, 120, Eckacote and Eckaglas (all kaolinites) are mined and
marketed by ECC Australia Limited.

Eckalite 1, 2, 120 and Eckacote are wet classified from the same feedstock and any colloidal plastic fraction (disordered kaolinite) seems to have been lost in Eckalite 1. Only Eckalite 120 (45% - 2 micron), a coarse micaceous china clay, seems to have any significant ceramic application -in casting slip. The other products are specialised paint, plastic and paper fillers.

I can attach specs for the Eckalites in JPEG or GIF format by e-mail if you
wish.

Eckalite 1 seems to be a similar product to EPK and has a the same iron content (0.58% Fe2O3), similar particle size range, but about one third higher TiO2 content (0.60%). This indicates to me that it would be inferior to EPK in porcelain and also inferior to Grolleg. So I think you actually have better products in North America to put in porcelains.
