Italian enamel over copper

I have purchased many Studio Laurana works, mostly the torch cut stuff

Cellini is another maker I like and have a few pieces from

However in the end you really hope to find a Paolo de Poli or Del Campo piece here in Italy

I am not sure who made this bowl (do not recognise the mark) but it is twice the thickness as the average Laurana piece

Unfortunately, a bit of enamel is missing
