Notes

No longer available. We do not have a physical description of this clay and have not used it. This analysis is not accurate since it shows no Fe₂O₃ (impossible so it is simply missed), so fired color can at least can be expected to be light buff. The low fluxing oxide content and high Al₂O₃, if accurate, means this clay would be kaolinitic and fire exceptionally refractory.

It is not clear what the relationship is between this and Monmouth Fireclay.

This material is no longer available but just ordinary kaolin would likely be a viable substitute (the body would fire whiter so this could be compensated by adding a little iron oxide to the recipe).
