There are a great many kaolins available from the UK. These are generally less plastic and fire to greater maturity than American counterparts (because they often contain significant K2O, MgO, etc). They are known for being cleaner and burning to a more blue-white color (whereas American materials more often burn to yellow-white).

Typecodes Kaolin
Pure clay mineral, there are many brand names of varying purity and iron content.
Typecodes Generic Material
Generic materials are those with no brand name. Normally they are theoretical, the chemistry portrays what a specimen would be if it had no contamination. Generic materials are helpful in educational situations where students need to study material theory (later they graduate to dealing with real world materials). They are also helpful where the chemistry of an actual material is not known. Often the accuracy of calculations is sufficient using generic materials.
