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>How do you boil a powder.....</p>
<p>it appears to boil as the CO2 is released</p>
Roll a note up and sniff it ? Thats one way clever dick hahah....
<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>I see when commenting on instructables there is &quot;a <strong>be nice</strong> comment policy&quot;. It is obvious that this does not extend to instructions as well, as it would most certainly not be nice to convince people to try this. CaO is a very caustic base (no, not an acid) . It should be handled with extreme care. Throwing it into water would release a very large amount of heat and cause a great deal of splashing, something which would obviously be undesirable.</p><p>That said:</p><p>My 12 year old cousin who is in to chemistry read this and almost had a heart attack laughing and we had a good time mocking your post, so some good did come from it.</p><p>Instructables, I apologize if I am breaking your &quot;be nice&quot; policy and I would have absolutely no issue with this comment being removed as long as these imbocilic instructions are deleted along with it.</p>
If you know so much smartie pants an your 12 yr old whizz kid (chuckling at this ?!? SAD!!) Why are you even coming on this section. Reading it ?? Now look what you have gone an done ! You look silly an whizz kid has an excuse he is only 12 yr remember thicko !!<br>
<p>As per Policy :<br> Nice Job !<br> I am positive that you have absolutely no idea what you are talking about and you are positively a danger to yourself. <br> What's worse, you are a danger to others. <br>It would be nice if Instructables would remove this stupidly dangerous post.</p>
<p>please remove these instructions</p>
<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
