apog

English: Translation
A lime powder derived from the shells of edible black freshwater trumpet snails, traditionally used in betel quid chewing.
Notes

The production process involves:\

  1.  Pyroprocessing: burning the snail shells on a bed of dry bamboo sticks in an alternating layer configuration.\
  2.  Slaking: quickly immersing the hot shells in cold water, transforming them into a soft, mortar-like consistency.
