Whats this in my Oslo?

Take a look at what I found in the ash, the yellow color stuff. I saw it last weekend, and thought it came off the wood. Cleaned the ash, and again this weekend I find the same thing in the same spot, only in this spot. It's soft, almost like ash. The picture is from the outside of the side door, looking down onto the stove floor.

My guess, so far is it's the insulation behind the burn plate on the side door. I can't see in there without taking the plate off. And I don't want to disturb the plate until I stop burning for the year.

Any other ideas what this is?

I don't know but I do know you need to take ash out of that stove more often.

Bart, Why do you say that? It's had to tell in the picture , maybe 3/4 inch deep on the floor. I get that in 2 days. Although this picture is from my wife burning all week. I normally clean the stove before each weekend burn. But 2 days or a week the ash is the same.

The stove is 13 years old with the cast iron burn plates. Never saw anything like this stuff. strange how it ended up in the exact location 2 weeks in a row. I like the idea of silica in the wood. The ash although not fully burned, shoulder season the last few days. Although I'm anal about having a clean stove, it holds the relighting charcoals better when there is a bed of ash.
