Step 6The chem lab!!!
Rinse with water three times the sand you want to use, removing all the floating stuff.
Slowly, add the acid, BE VERY CAREFUL, USE GLOVES AND A ROOM WITH CIRCULATING AIR,
Decomposing the shell is a quite safe process that only produces bubbling CO2 but the foam can overflow.
Once the bubbling ends , rinse and clean with water until all the mud is out.
