Quick lime is a corrosive acid so be VERY careful
Step 1: quick lime
mash up the seashells or other lime product into a powder
heat it on a stove (boiling it )
it should look acidy(i haven't done this before) and then, add in water let it react and slaked lime!!!
Note:seashells are calcium carbomate CACO3 and the quick lime is CAO and finally slaked lime CA(OH)2(aq)
