But very very important, before you blend or grid them, make sure to cleaned it well and make sure they are free from any bacteria. Here are my procedures I normally take:

  1. Store used egg shells in a jar or a storage box and put it in fridge. I don’t leave them in carton box because I don’t want it to smell. Make sure to store them in fridge.
  2. Once you got a batch, wash them first then boil them for at least 10 minutes. This will kill all the bacteria.
  3. Let it cool and dry. You can put it in oven for a few minutes to further dry if you like. I normally skip it (but make sure boil them well).
  4. After they are completely dry, grind them until you have a nice power substance.
