this is how to make quicklime out of seashells and then make slaked lime which is a good mortar and putty and paste . to make quicklime all the materials are as followed
1)a container of some sort
2)any lime product(i use seashells)
4)time i guess??
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)


<p>This is total rubbish! You need a fire or a kiln to convert calcium carbonate from shells or limestone into quicklime - high temperatures and a dry environment! Plus, quicklime is a strong alkali, not an acid. This article is wrong, dangerous and irresponsible and should be taken down.</p>
<p>How do you boil a powder.....</p>
<p>it appears to boil as the CO2 is released</p>
<p>CaO is a strong base... if you're dealing with any acids here (beyond identifying limestone) you're mistaken somehow.</p>
After boiling my rocks my lime still looks alkalineny. Do I need to take more acid?
<p>If you are trying to help by answering questions you know nothing about, then you are actually doing us a disservice by giving bad advice. Please be aware of this next time.</p><p>Never tell people how to do something if you have not done it yourself. It is dangerous</p><p> If you want to help, you can point them to articles or films that may help them out instead.</p><p> What does &quot;acidy&quot; mean?? You can not see acid, only pH testing strips, liquids can tell you what is and isn't an acid. </p>
&quot;It should look acidy&quot;? If you don't know, don't tell people things that are just not true, either.
quicklime is CaO and is a base..
calcium carbonate (CaCO3) is insoluble in water you must drive off the carbon dioxide to get calcium oxide (CaO) it takes quite a bit of heat
