We inherited a piece of curupay lumber when we moved here. A meter long, perhaps 2″x3″, it weighs much more than any unsuspecting person would imagine. Curupay is used for beams, and though it has about the highest heat output of any wood here, its price is such that you’d be crazy to burn it. Unless, of course, you happen to have had incompetent local aluminum door installers destroy your floor and the frame of the wooden door they removed.
The pieces have sat, undisturbed, in our carport for a very long time. I tried cutting one with our crappy little German circular saw, which basically burned its way through the board, but my new table saw zipped right through them.
This is what just one of those pieces looks like burning. I’m scared to put in more than one piece. You can feel the heat across the room. Especially nice on a cold day like today, in a typically uninsulated Uruguay house.
Would love that kind of wood that would burn a long time. Would save several night fuel additions on these colder winter nights.
