Old Windows Counter Weight.

he guys, I am in the process of renovating my kitchen, and the old windows have 4 counter weight I think they are cast iron.
would this interest any of you forgers out there?

 

a cast iron typically no but if they are wrought iron then they be gold

 

How would check this?

 

Cast iron, either low quality or high. could have swore the ones in a house from 1804 were wrought.

easiest way is to break one and if a stringy grain the they are wrought. A clean break is cast iron

 

I would say break one and post a picture. To test, i will cut part way through a piece with a saw or angle grinder, put it in a vise, and beat it with a hammer, wrought will usually start to tear apart in a stringy almost wood-like fashion, while cast typically snaps with a grain that looks like sand, either fine or course.

 

Ill keep you guys posted on the results, haven't had time to make it to the shop and beat the snot out of the counter weights.
still working on the kitchen reno.
