Pottery Mark Query - heart inside a pentagon OR heart in a house:- Hi, Bought the vase in a Charity Shop because I liked it. It is 10 inches high, top of the base is 3.5 inches and the base is 3 inches.

The vase is not round at the top or the bottom, more of a squashed shape? Multi rings of glazed colour from a plain stone to the top of a shiny, sparkly purple colour?

The base has 2 straight line indentations and a mark that should be described as a heart inside a pentagon that is made with a continuous line however I like to call it a heart in a house!!??
Any help appreciated.

Thanks for taking the time in reading this.

Regards

Paul
