A fabulously decorative vintage piece. 
These were used to make rubber gloves, by dipping the mould into a rubber solution and leaving to dry. The rubber was then rolled off the mould and et voila. . . it was a rubber glove. The machines these things were attached to can be seen in the photos. 
This particular mould is porcelain, from Belgium and was rescued from a closing factory. 
These are just far too decorative to smash and send to landfill. This is a size medium, with a brown band around the base.
They look great on a mantle or as part of a vignette and truly lovely adjourned by jewellery.
