Notes

Laterites are earthy materials having high Al₂O₃ and low SiO₂ content (compared to typical sedimentary clays). They also can have very high iron contents (quadruple or more that of terra cottas). Laterites are refractory. Materials from different places have differing properties and chemistries depending on the range of parent rocks from which they weathered and the extent of oxidization and leaching experienced. Laterites are not plastic so have limited use in ceramics (although they can be employed as an inexpensive source of alumina in red-burning clay bodies).

We have rounded off the analysis from the IMCO web page. It sums to 100+LOI so needs to be retotalled.
