You might be thinking of CCA (Chromated Copper Arsenate). It's still in use but harder to find vs. forumations that don't use arsenic. https://en.m.wikipedia.o

- jessaustin 9y agoI've seen CCA lumber before, but the stuff I'm talking about is different than that. You have to wear gloves while handling it, and if you touch your face you'll be crying the rest of the day. It's nasty shit, but it doesn't rot.
- Mtinie 9y agoCreosote? Railroad ties are coated in it and for a long time it was one of the main wood preservatives used. It's tar-based, nasty stuff and you'd definitely want to use gloves when working with it.
- jessaustin 9y agoGood guess, but this wasn't creosote either. It was much more irritating than that. Who knows, maybe it's an especially noxious mix that was only used by sawmills here in the Ozarks? Like I said, we can't find it anymore. My dad had a bunch of 16' 1"x6"s for fence boards in the last batch treated at the last sawmill we knew that could do the treatment, and that was some years ago.
