Making charcoal powder #6

Open jes opened 5 years ago

jes commented 5 years ago

The most efficient method I've found so far:

  1. Buy a bag of barbecue charcoal
  2. Buy a kitchen food blender
  3. Chuck a little bit of charcoal in the blender (not too much or it overloads the motor -- or maybe my blender is just too weak)
  4. Grind it in the blender for maybe 30 seconds
  5. Empty the contents of the blender through a sieve into a big pot
  6. Refill the blender with fresh charcoal
  7. While blending the second load for 30 seconds or so, shake the sieve contents around to get the powder into the big pot
  8. Tip the remaining sieve contents into a secondary pot
  9. Tip the contents of the blender through the sieve into the big pot
  10. Tip the contents of the secondary pot into the blender, and top up the blender with extra charcoal chunks
  11. Repeat from step 7 until you have processed enough charcoal.
