Petrus Regout white mixing bowl, vintage

A fine white Petrus Regout mixing bowl. The bowl is sturdy, so it stays put. What looks better, batter in a plastic bowl or the batter in this sturdy white porcelain mixing bowl? I choose porcelain, it feels and looks different. The vintage mixing bowl by Petrus Regout is in good condition, see the additional photos above. The mixing bowl is marked on the bottom with a 9 and a Sphinx Petrus Regout en Co.
