    While pulling the coals forward this morning to burn them down before a reload I came across the biggest clinker I have ever seen in my stove. I buy my wood so i am not sure what I have really been burning, but its all quite dry (about 12-14%). Clinkers are relatively common, but pretty small in size, golf ball sized. This thing was just ridiculous!

    Figured it had to be shared.

    That's a big one!

    I get them about half that size frequently when burning doug fir. They actually sound like glass when they fall into the cast iron inside the stove. Very little ash with douug fir but I do get those klinkers.

    I'm working on a big one in our stove right now. When you only clean it out once a month, they get big. The trick is removing them without breaking them. Maybe we should have a biggest clinker contest?

    That big clinker should prolly be classified as a clunker!

    That is a big mutha. So I know it has been asked before but where do these come from? I guess I don't remember them when I was a kid in the old smoke dragons. I get these all the time... I'm burning mixed wood.

    Just my theory but since these stoves bake the volatile material out of the wood and then burn the gases more than they just burn the wood like the old stoves, I think that contributes to stuff like that ending up in the ashes. They are common in the burn pots of pellet stoves with less than primo pellets. Some kinda junk in the wood left over after the bake sale.

    I know of clinkers that came from the old coal stoves, but clinkers in a wood stove? How does this figure? So far I haven't come across any...I burn slab wood which is probably the lowest grade of combustible material one can burn. That's one helluva biggun though! Nice find! I like the meteorite idea, lol. You know someone out there will pay top dollar for that. Good luck!

    I get them all the time here and we've talked bout this before.. I feel it's caused by ashes built up and wood added on top so heat and pressure compress the ash or as Jake says I am creating diamonds albeit "in the rough" lol..

    So they are a result of the heat in the stove and stuff from the wood. I have to say I doubt the type of wood matters....

    I found a big one when I cleaned out the ash from the Opel yesterday. Just tossed it into the ash can but maybe I'll dig it out if we're having a biggest clinker contest. What's the prize?

    We are all pretty sure its junk (minerals/silicates) in bark/dirt that fuses together in the ash.

    Maybe burning pretty hot in modern stoves contributes to it.... I am not sure what wood i am burning, as I buy wood, but i know there is a bit of dirt on the logs, not much, but some. Sure that is causing most of it.

    Raining and 49F, so I cleaned out the stove. There was a big clinker in it, but it started breaking up when I shoveled it out. I took a picture anyway. Even the remaining part is huge.

    Yeah, how is that working out for you . . . did you give your wife a bunch of the clinkers and tell her that in a few billion years they'll be bigger and better than the Hope Diamond? ;)

    I'm not sure how well that one would go over. "Here ya go honey. I know it's a little rough right now, but hope for a diamond." Then duck and cover, those big clinkers are heavy.

    I have seen these when shoveling out my stove from time to time. There not really like coal clinkers as there not hard. The things i get are easily busted up if u try, and look like that giant one with the shovel in the pic. I just assumed it was from the heat, resin, wood weight and moisture realeasing when the wood burns into the ash under it.
