Sardinian ceramics

I really like pieces from Claudio Pulli but I recently have seen many similar style pieces that were unsigned or off
so I figured somebody must be copying his style of glaze

anyhow I am in Sardinia and saw this mirror (which I bought) in a shop signed by Ignazia Mattana of Assemini, seems she might have apprenticed under Pulli but not certain about that

I bought several other signed pieces from Pulli and there are more ceramicists here who copied him ;-)
