Preventing Toning (especially of Silver)?

[Debbie 58]

Just how I like a coin to look, and a good enough scan to see the sharpness of hair and fingers! I absolutely could not collect anything different. That's not to say I wouldn't buy different...I just wouldn't look at them and sail away to faraway thoughts and imaginings, as I often do with the coins I love!

I agree too Coinery, I love nicely toned coins too. In fact I look at my collection of shillings rather like a chocolate box of different shades which highlights the fact that the collection is unique and reflects my choices.

What a great response! And surely the perfect attitude to coin collecting? We men can be far too Aspergic sometimes, especially about piddling little unimportant factors Thank you for keeping our feet on the ground.

Top marks for that philosophy. It beats collecting by numbers on slabs, for which read "let's see if I can get the highest average grade across the collection based on someone else's opinion", which is the game played by all those competing for the best registry sets with the TPGs. If you like a coin, then buy it. Don't be put off because someone else has marked it down. We all have less than perfect coins which tick our individual boxes for whatever reason.

I'm not a 100% certain, but aren't sulphates involved in the tanning of leather?

Yep, Ferric Sulphate, Fe2SO4 also known as Copperas.

I too am not 100% certain, but wasn't this collected in former days as dog's no.2s?

Not if Copperas is correct. If the latter, it would be called grrrass. Or if sheep's no 2s, woolas, with apologies to the not so honourable former member for Oldham and Saddleworth.

'chocolate box,' what a delightful and poetic comparison, very nice!

Remind us who that was, Rob?

Nobody has spotted it, but Ferrous Sulphate is FeSO4, not Fe2SO4. Embarrassing as I studied chemistry at Uni and that's an 'O' level mistake! Senior moment is my excuse.

ditto on all counts.

Ferro Di-sulphate? (Just a guess - I did get my Chemistry O Level but that's as far as it went apart from producing bright purple dyes at home from potassium permanganate )

It might be if this compound existed, but it doesn't, at least not in a stable condition. The other Iron Sulphate is Ferric Sulphate, which is hydrated Fe2(SO4)3 and is an orange crstalline salt.

Ok. I'll take your word for it - my chem is very very rusty indeed. Though if it was better I could cure that rust...
