China stone[edit]

In the US, when listing the British clay/kaolin "china stone" in a glaze recipe or buying it from a supplier, it is usually referenced as "Cornwall Stone" [1]. This may be just a marketing issue. It would be good to identify the differences and similarities between the terms. WBardwin 17:47, 11 November 2005 (UTC)

-China Stone is just another name for Cornwall Stone, and is a form of decayed feldspar similar to Petuntse, but not the same, as China Stone refers specifically to the kaolinsed feldspar which occurs only in Cornwall, England, displaying qualities unique to that area. Therefore your contribution should be added to a seperate wikipedia article for China Stone.--Badharlick 06:14, 7 February 2006 (UTC)

Hello Badharlick, I’ve previously created a China stone entry – I’ve now added a link to this in the petunse section – where you'll see that rather than being decayed feldspar it's actually partially decomposed granite ... I could have been more exact and used kaolinised rather than decomposed but thought it perhaps a little too specialised a term for a short encyclopaedia entry Regards, Andy
