Limestone is broken down by thermal decomposition to make quicklime (calcium oxide). This is then converted to slaked lime, limewater, and finally back to calcium oxide

so..how would i know if it is already a quicklime? what would be some significations of the sample becoming a quicklime? I'm working on a research paper concerning the utilization of mussel shells as a component in making tiles and since quicklime which could be obtained from chalk, lmestones, marble and seashells could be an alternative to cement and would need some advices from you.^__^

@HUGZ012 Different texture and different reactions.

Limestone is calcium carbonate - relatively inert, although it reacts with acids (like all carbonates) to produce a salt, water and CO2

Quicklime is calcium oxide. Tends to be "softer". Reacts with water as seen further on in the video.

Heat It until what colour ?? please tell me ..... i used a chalk and i burn it until black colour .... tell me please

@Greenfulness I'm actually using marble, but limestone does the same. Limestone is calcium carbonate so it decomposes to give calcium oxide and carbon dioxide.

I wonder if the chalk you are using is for writing with, and so is calcium sulfate based?

good video, very helpful, thanks!!
