Minerals, metal. We've been digging them up for such a long time. The bronze age, the iron age, copper, tin....
Everyday wonders. Something to think about when we roll out the aluminium foil.
I try to give the old tins I find some thought in respect of all that went into making them.
(Oh, and of course if you'd like to see more tins and toolboxes you may find them by clicking here.)
