Please log in for more thread options From a casting point of view, casting these objects can be screwed in
the melting phase. A dirty casting, may have too much porosity, if it's
a remelt as opposed to a smelt may also cause this problem.
Usually if you find a bad product you tell the company that manufactured
it and give them a chance to rectify the situation. If the products are
still crap, you go with a good producer.
Pure iron is difficult to get these days, so the firepots that are
cracking may not be iron at all.
I was thinking that with the alloys available today, you could feasibly
construct a firepot, but you would have to select the right alloy in
plate form. Plate is less likely to crack than a casting.
