In case we see more than one cm from the cutting,
there’s been made a mistake during the

be produced

In the inside of the chips prism there’s a temperature of 60-70°C.
The material dries to a water content of 35%, that is already
economical to be transported at. There’s no spontaneous
combustion! Safeguarding!
