I had some willow shavings soaking happily in my potash alkali for a few weeks. Time had come to do something with it. Going back to the advice from Bio-composite Centre I re-boiled the solution with a bit of whisk/friction. After a 2 hour cook the shavings were scooped into my make-do metal mould. It was G-clamped up as tightly as possible and left to dry.
The shavings were checked after 3 days. Were the wood had dried and had been compressed the most, there was definetely bonding. Exciting stuff!
The sample was placed back in the mould and the whole thing was placed over a stove to apply some heat. It was left there to sizzle away until I was sure all the water had evaporated away.
Once everything had cooled, the clamps were removed. The shavings had successfully bonded together. The surface that was on the metal mould side and over the heat had a very smooth and shiney finish. I had created my own glueless particle board, a course masonite board.
I can only presume the cooked cellulose and lignin had acted as a bonding agent when heat and pressure is applied. Unforuntately the the material isn't water resistant, but there is still some potential with this aplication within my woodland.
