Old family mixing bowl

My Nanna gave me this seriously old mixing bowl - it was her great grandmothers!! It doesn't have any markings on the base to tell me where it came from unfortunately but it's full of cracks and character. I actually haven't used it yet though as I've been too scared I might break it... but I have told myself it's been around for so long what could I possibly do to it... or if I break it I will have to go and learn to do a Mosaic!
