If you’ve read some of the recipes I share on this site, you’ve probably noticed that calcium carbonate is a commonly used ingredient. Although it’s easy to find in stores, I personally prefer to make my own ingredients whenever possible.
Calcium carbonate is a chemical compound with the formula CaCO₃. It’s extremely abundant in nature, found in rocks all over the world as well as in shells and the skeletons of organisms. Besides its use in paint recipes, it’s an essential ingredient in the production of glass, cement, and other materials.
In the case of paints, we can use it to make lake pigments or gouache, for example.
Bowl or similar
If you don't have one, you can use a palette knife.
Or a marble slab

If calcium carbonate is used to make lake pigments, it is important to consider that the color of the eggshells used can slightly influence the final shade of the pigments obtained.Eggshells are 94% calcium carbonate, so you can use them in the same proportions in the recipes I give you.
