It's cold, wet and incredibly windy today and getting dark early (4:30PM). Not even mid Winter yet and I'm counting the days to Spring.
I've been having the fireplaces going constantly; and so hot that a cleaned fireplace will still be hot enough to lite twigs (guess I can get that Scout badge now, don't even one match) without the need to use matches or lighter.
So I've had some ash to make a glaze with.

Note: Ash changes from tree to tree, and environment to environment: Basically a result of what it takes up from the ground around.
