I've been trying to find some information on working with Bamboo. I understand heat is used to "carbonise" it and that this preserves it too. Culms are heated over a fire and then bent in order to straighten them. Some bamboo I split and used as hoops over beds were eaten by borers in one season. Any pointers?
i use a little propane torch for heat-curing bamboo for making flutes and soem other craftwork. move slowly and steadily with a low flame along the pole,you'll see the color change from green to yellow,brown,dark brown,almost like you're airbrushing it. keep a rag handy for wiping down the surface resins that exude from the skin and ends.go from 1 end to the other so as not to trap moisture in spots.
it can help prevent cracking. i've never tried straightening it with heat but i know it's used for bending,it's really steam-bending. if the boo is fresh/wet/green then the heat is essentially making steam.adding sand inside prevents it from creasing . it's important to either 1: knock a hole through the nodes inside, or 2: drill a tiny hole between each internode/joint to relieve pressure,otherwise it could explode!!!bamboo in the campfire was used in asia to scare away tigers i heard.
heating,and a little beeswax/tung oil mix are the only things i use to preserve bamboo.it doesnt need much help! takes forever to decompose.
www.bamboocraft.net is a great site for these kind of questions.
Tribal, Thanks for putting me on the right track. It led me to Boucherie method - which led me to this. http://abari.org/treatment Really simple and easy - will try in the spring. After the Boucherie method I'll probably still try carbonising long pieces by "smoking" them in a pipe , vertically over a fire... might work.

We have used the Boucherie method, it's actually quite difficult, with the main problems being leaking fittings and having to treat bamboo on the same day it's harvested.
