'I've found a marble made of real marble, dad!' came the call as we rushed round shutting shutters, evicting the cat, checking that we'd evicted the cat, returning for counterpart driving licences, checking that the cat was still out, etc. With impressive patience, Ben took the time to look at the find and suggested that it was made of clay, not marble.
The find travelled on the plane with us (it did not set off security checks) and came home, where it is now sitting next to the computer. But what is it for?
Why would someone fire a slightly irregular ball of clay, around 3cm/1 inch across? Does it have a practical use in French tradition, or was someone making an over-large marble to play with? Any suggestions, wise or otherwise, are most appreciated!
