What material can square candle glass be made of?
The glass materials are mainly as follows:
1. Soda lime glass
Square candle glass, bowls, etc. that are used daily are all made of this material, and it is characterized by small sudden temperature differences. For example, if boiling water is poured into a glass just taken out of the refrigerator compartment, it is likely to burst. In addition, it is not recommended to heat soda lime glass products in a microwave oven, because there are also certain safety risks. To
2. Borosilicate glass
This material is heat-resistant glass, and glass crisper sets commonly found in the market are made of it. It is characterized by good chemical stability, high strength, and sudden temperature difference greater than 110°C. In addition, this type of glass has good heat resistance and can be safely heated in a microwave or electric oven.
But there are also some things to pay attention to: First, if you use this kind of fresh-keeping box to freeze liquid, be careful not to overfill it, and the lid should not be closed tightly, otherwise the liquid that expands due to freezing will put pressure on the lid and shorten it. The service life of the lid; secondly, the fresh-keeping box just taken out of the freezer cannot be heated in a microwave oven; thirdly, do not close the lid tightly when heating the fresh-keeping box in a microwave oven, because The generated gas will squeeze the lid of the box and then damage the fresh-keeping box. In addition, long-term heating will also make it difficult to open the lid.
3. Glass-ceramic
This kind of material is also called super heat-resistant glass, and the glass pots that are very popular on the market are made of this material. Its characteristic is that the heat resistance is particularly good, the sudden change temperature difference is 400 ℃. However, currently domestic manufacturers rarely produce glass-ceramic pots, and most of them still use glass-ceramics as cooktop panels or pot covers, so there is still a lack of standards for such products. It is recommended that consumers check the product quality inspection report in detail when purchasing to fully understand the product performance.
4. Lead crystal glass
It is commonly known as crystal glass, which is generally used to make goblet. It is characterized by good refraction, good hand feeling, and a clear and pleasant sound when tapped. However, some consumers questioned its safety, believing that using this kind of cup to hold acidic beverages would cause lead to precipitate and endanger health. In fact, this kind of worry is unnecessary, because the country has strict regulations on the amount of lead precipitation in such products, and has set up experimental conditions, which cannot be replicated in daily life. However, experts still recommend that you do not use lead crystal glasses for long-term storage of acidic liquids.
5. Tempered glass
This material is made of ordinary glass through physical tempering. Compared with ordinary glass, its impact resistance and heat resistance are greatly enhanced, and the broken pieces have no sharp corners. Since glass is a brittle material and has poor impact resistance, even tempered glass tableware should be protected from impact. In addition, do not use steel wool when cleaning any glass products. Because the steel wire ball will scratch the glass surface invisible to the naked eye during friction, which will affect the strength of the glass product to a certain extent and shorten its service life.
