Eggshells are notoriously excellent fertilizers. They consist of calcium bicarbonate and give the soil an extra supplement of calcium but also of potassium.
It would be an unforgivable mistake to throw away the eggshells as they can be very useful not only as natural fertilizers for the garden
The shells could be chopped up and mixed with the soil. Alternatively, they can be boiled in water for ten minutes. Then by filtering the liquid it can be used to irrigate plants, especially those that need calcium and potassium supply. However, eggshells have countless other ways to be used, such as in coffee.
Remove the bitterness and acidity from the coffee
We Italians are big fans of coffee but some prefer to dampen its bitter taste with milk or cream. An alternative, which does not change the taste but serves to remove the acid, is the eggshell. The reason is very simple: the eggshell, which consists of calcium carbonate, is alkaline and therefore manages to lower the acidity of the coffee. We must first wash the eggshell well and make sure that there are no egg white residues. Then, when coarsely chopped, add it to the water in the lower part of the suede. We then continue to add the coffee and turn on the fire. The difference will be noticed immediately. The bitter aftertaste will disappear.
When nails appear weakened and break easily, we must remember the properties of eggshells. Because they are made up of calcium carbonate, they will be an excellent strengthener for your nails. Let the eggshells boil for a few minutes so that any bacteria are eliminated. Now we have to dry them in the sun and then reduce them to powder with a mortar and pestle. We add an even coffee spoon to a glaze. Let us shake it vigorously and then apply on the nails. This method is equivalent to a refreshing mask for brittle nails.
If the mixer no longer chops
Eggshell is perfect for grinding mixer blades. We must first make them as hard as possible and therefore we put them in the freezer. Now let’s pour them into the mixer and add a tablespoon of water. We run the mixer for a few minutes. In the end, our blades will be razor sharp and return to cutting as before.
It would be an unforgivable mistake to throw away the eggshells once you discover how you can use them.
It sounds bizarre but there is a reason why many have cat and dog hair left on the couch and their own hair on the brush.
