I remember years and years ago reading about somebody's idea for wooden ablative heat shields for space capsules. Apparently wood does something special when subjected to that kind of heat, I don't remember what. It was a neat article.

Japan loves their wood. Woody little pedos, them.

The RCC heatshield parts on the shuttle were made out of rayon coated in resin, carbonized, then sealed with sodium silicate
Basically a wooden heat shield if you ignore most of the process

Isn't that the part that failed when the Columbia was incinerated?

Yeah, one of the CAIB appendices details how they were made

It didn't fail when incinerated. It failed when it was hit at launch from foam causing a big hole. The plasma went in this hole at rentry causing the frame to bend and the vehicle to fail.
