I'm sure the answer to this question is no, but I thought I'd pick all the tipiters brains on the subject.

 

 

 

Is there a regular furnace close to the blast furnace where I could make cannon balls?

Im 90% sure there isn't.

Last time i looked, people smithed the items and then sold them to the shop.

It's even better to alch them, just so you know.

 

Also, following Tip.it's map, there is no other furnace in Keldagrim other than the Blast Furnace.
