I like the idea that it is salt from the castle sh1te pit.
Not so sure it is - a long time ago I thought it might be something like that so I scrapped some off, sniffed it and then tasted it.
No taste at all - definitely not NaCl.
...but I partied all night!
But if it's an old deposit from the castle toilet then it would be more likely to be potasium nitrate - Saltpetre.
But I am very sure this occurs elesewhere in Reigate, Peter told me he did not find it in another nearby site where I had said I was sure I had seen it, I shall have another look as I am sure it's there but cannot remember exactly where.
Very interested to see results of any analysis - well done Peter.
