I've a few Venini items that would be consigned to the charity shop if the above "definite" assertions about surface texture and base finish were taken at face value. Even the finest pieces of Fulvio Bianconi decorated a fasce
have some surface irregularities. Not
that I'm saying the vase in question is Venini, of any great quality (sorry), or even not from China... but broad generalisations such as above are apt to confuse or mislead.
