Today was quite relaxed. Several smelting experiments with malachite were conducted but the day focussed on updating and reworking the documentation. A disagreement between between P. Castro and M. Legault lead to an epic battle but fortunately nobody was hurt.
As there is nothing more to tell today, here is the next recipe from the LEA bakery:
Copper pot made of malachite
Materials:
- High-resolution balance
- Clay crucible
- Fire pit
- Bellows
- Fire tongs
- Hammer
- Chisel
- Bucket
Ingredients:
- 20 g malachite from Kongo
- 2 g charcoal dust
- 1 handful of soil
- 1 bag of charcoal
- 10 l water
Give about 1 g of the charcoal dust in the crucible. Shake the crucible thoroughly to disperse the charcoal dust on the crucible walls. Now add the malachite and put the other 1 g of charcoal dust on top of it. Close the crucible with the soil and put it cautiously in the pre-heated fire pit. Cover the crucible with charcoal and cook it under constant addition of charcoal slowly for about 45 min at 1000 °C. At the same time fill the bucket with water and place it nearby. Use the fire tongs to take the crucible out of the fire pit and cool it down in the water bucket. Open the crucible with hammer and chisel and serve it.
