Oven warming up. This phase is called tempering. It will make the bamboo stiffer, more resistant to taking a set, will dry the bamboo, help keep the strips straight and darken the colour of the strips. The bamboo will regain moisture and stabilize to its environment, just like wood.
I will temper at 360/370 for 20 minutes.
I will take it to 375 as there will be a 15 degree drop after putting the cold bamboo sections in.
In they go and ......
Timer set at 10 minutes and going. After 10 minutes, I will turn the sections end to end to counteract any hot spots in the oven and bake for another 10 minutes.
There is our temperature drop in less than one minute.
