I contacted my stove manufacturer (Hearthstone) and they emphatically said not to use them in a Hearthstone (soapstone and cast iron) stove.

Reason: They generate too much heat too quickly and can cause the soapstone to crack. I thought I had saved the email from them, but can't find it.

They did not offer any comment on straight cast iron, or cast iron with a glass front. But then again, I only asked about my soapstone stove, and they answered that inquiry directly.

For what it is worth.
