The surface of glass tea sets appears to be very transparent, but there are still considerable differences within. Genuine tea sets have uniform glass thickness, which allows for excellent transparency under sunlight, and the sound produced when struck is crisp. Most of these sets are heat-resistant, preventing them from exploding.Some glass tea sets, although relatively inexpensive, have a dull sound when knocked, and they tend to be somewhat cloudy. Their heat resistance is average. Especially for glass tea kettles used for boiling herbal teas, if the heat resistance is poor, the risk is significant!

Cleaning Method:

Many people like to drink tea, but it is difficult to remove the tea stain on the cup. The layer of tea stain on the inner wall of the tea set contains a variety of metal substances such as cadmium, lead, iron, arsenic, and mercury. When drinking tea, these substances enter the body and combine with the nutrients in food, such as protein, fat, and vitamins, to form insoluble precipitates, hindering the absorption of nutrients. At the same time, these oxides entering the body can also cause pathological changes and dysfunction in the nervous, digestive, urinary, and hematopoietic systems. Especially arsenic and cadmium can cause cancer, cause fetal malformations, and harm health. Therefore, those who have the habit of drinking tea should regularly and in time clean the tea stain on the inner wall of the tea set. In order to make you no longer worry about this, the following introduces several methods to remove tea stains:

(1) To remove tea stains on metal tea filters, if the tea filters become dark and unresponsive to medium-strength cleaners, soaking them in vinegar or bleach can easily remove the stains.

(2) To remove tea stains from tea cups or tea pots, after using them for a long time, a large amount of tea stains will accumulate. You can easily remove them by rubbing with a sponge dipped in salt.

(3) To remove small tea stains, soak the affected area in a solution of bleach or cleaning powder and leave it overnight to remove the tea stains.

(4) Use toothpaste or crushed eggshells to scrub, and then rinse with clean water.
