Lime is made by first burning chalk or limestone to form quick lime (calcium oxide) and then slaking the quicklime with water (forming calcium hydroxide). If no clay is present in the original limestone or chalk, the resulting lime is said to be ‘non-hydraulic’.
How to Make Lime?
Making lime is an age-old process that has been used for centuries to make mortar, plaster, glass, and other materials. It is a simple process that requires few ingredients, and is surprisingly easy to do. The following steps will guide you through the process of making lime.
First, you will need to gather your ingredients. You will need limestone, water, and a heat source such as a fire or oven. Limestone can be purchased at most garden and home improvement stores. The amount of limestone required will depend on the size of the project you are working on.
Secondly, you will need to break down the limestone into smaller pieces. This can be done by either chipping or crushing the limestone with a hammer. Once the limestone is in smaller pieces, it is ready to be heated.
Thirdly, you will need to heat the limestone. This can be done by placing the limestone on a fire or in an oven. The fireplace is the best option for heating the limestone, as it will heat the limestone more evenly. The temperature should be kept at a steady, medium heat for about an hour.
Fourthly, you will need to add water to the heated limestone. This can be done by either pouring water directly
