Featured Help with a small green-silver glazed jug.

I need your help to identify this small carafe. It is about 15 cm high and has a very thick manganese green and silver glazing.
The silver color is similar to lead. The clay is a red color and under the base there is a 3 spur mark.
I would like your help to understand its origin and use.
Thanks again
Giuseppe

 

Nice glaze.

I was wondering if it was raku but that's about all I've got.

 

Thanks. At the beginning I thought too of a Raku ceramic. But then because of the 3 spur mark I thought it could be Chinese.

 

Belgian pottery from the 20s often has that three spur.

 

Thanks. Your indication was very useful. I did some research and I think it could be a Belgian jug. I have seen that numerous Belgian manufacturers have used this style (Airan, Thulin etc ....). Then the glazing so powerful seems to be typical of these manufactures.

 

It wouldn't surprise me if it were Belgian. Certainly has the look and the right clay.
