I mentioned in another thread that I wanted to try some wood bricks to see if my wife could start running the stove. Tonight I had her put 2 4lb blocks and 1 6lb in on a small coal bed. That was at five o'clock. The air was all the way down by 5:30 and stove is cruising at about 525. Took a couple pics but they are useless. These do appear to burn clean. Overfire seems to be a real possibility. If I can get a decent burn cycle out of them I may get some delivered. Want to practice a couple more times to see what the best way to arrange them is. Too much air appears to me would be a problem.
