What is the use of drying eggshells in the sun

Dried eggshells can be used to supplement calcium, improve soil, clean homes, make handicrafts, and relieve excessive stomach acid. The main component of eggshells is calcium carbonate, which can have various practical values after being dried and crushed.

1. Calcium supplementation

Dried and crushed eggshell powder can be used as a natural calcium supplement. Each gram of eggshell powder contains about 380 milligrams of calcium, and its absorption rate is similar to that of calcium carbonate tablets. When using, thoroughly clean the eggshell, boil and sterilize it, grind it into fine powder, and then add a small amount of it to flour or Congee. Osteoporosis patients or adolescents during their developmental period may use it as appropriate, but daily intake should be controlled to avoid the risk of constipation or stone formation caused by excessive calcium supplementation.

2. Improving soil

Eggshell powder can regulate soil pH and supplement minerals. Crushing sun dried eggshells and sprinkling them into acidic soil can neutralize pH and provide elements such as calcium and magnesium, making them particularly suitable for growing crops such as tomatoes and peppers that are prone to navel rot. It is recommended to mix with the surface soil during use to avoid excessive accumulation and pest infestations. Eggshell fragments can also block the damage of mollusks such as snails to plants.

3. Cleaning Home

Grinding eggshells and mixing them with white vinegar can make natural cleaning agents. Its micro sanding property is suitable for wiping stubborn stains on the surface of stainless steel sinks, glassware, etc. The calcium carbonate component can react with acetic acid to form foam, enhancing the decontamination effect. Coarse grained eggshell fragments can be directly used to clear drainage pipes, but they need to be washed with hot water to avoid residual blockages.

4. Handicrafts

Fully dried eggshells can be used as creative handmade materials. Miniature potted plant containers, holiday decorations, pendants, or collages can be made through drilling, painting, and other techniques. During processing, the inner membrane should be retained to increase toughness, and the edges should be sanded with sandpaper before operation to prevent cuts. The eggshell mosaic technique is commonly used to decorate the surface of picture frames or vases.

5. Relieve stomach acid

In traditional medicine, roasted eggshell powder is used for symptoms of excessive stomach acid. Calcium carbonate can neutralize stomach acid and alleviate heartburn, but modern medicine recommends standardized drug treatment. If you need to try, the dosage should not exceed 1/4 teaspoon each time, and should not be taken together with tetracycline antibiotics. Patients with gastric ulcers should prioritize seeking medical attention rather than relying on this method.

Pay attention to hygiene and safety when using sun dried eggshells. Raw eggshells may carry Salmonella and need to be boiled in boiling water for more than 10 minutes and thoroughly dried. Powder storage should be sealed and moisture-proof to avoid mold growth. For horticultural purposes, it is recommended to stay away from pet activity areas to prevent accidental ingestion of sharp fragments. People with stomach discomfort should consult with long-term calcium supplements before using eggshell powder. Regular monitoring of blood calcium levels is necessary. When composting eggshells with other kitchen waste, they need to be crushed to accelerate decomposition.
