Scale like build up on floor of stove.

[Jamess67]

Hey Guys, here is one for you. I have never seen this before but when I clean the ashes out of my stove, Im encountering a scale like, rock hard, formation on the fire bricks. This year Im burning some free wood that I thought was something close to oak. However when it dried out , the splits are very light weight . So now Im thinking its some kind of Maple.

Is this scale residue from the wood or part of the fire brick?

Thst looks like some kind of resin out of the wood to me. Kind of strange that it's not burning off. I'll be watching this to see what others think about it.

I've been getting that as well right by the dog house air inlet of my stove. I thought it was the brick coming apart at first as well.Upon further inspection, I think it is just ash that gets fused together from all the heat.

Looks like a clinker to me: https://www.hearth.com/talk/threads/biggest-clinker.79475/

Yes, it's a clinker. We get folks wondering about them every year around the time they first clean out the stove. It's normal. Some species of wood produce more than others.

Clinkers . . . normal.

Most reports of it that I have seen here were when burning Elm. Just another one of its charms.

Learned something new, clinkers. I've never seen them in the oak I burn. We do clean the ash out before the weekend burns. Is the consensus it silica? Seams like you wouldn't get to the temperature needed to make glass. But maybe it's another form.
