How to Discern the Quality of Glass Water Bottle

Glass water bottles can be made of high borosilicate heat-resistant glass water bottles, crystal glass water bottles and double wall glass bottles by category. Because the performance and quality of these cups on the market are different, their quality directly affects our health. What kind of glass is good? How to distinguish the quality when choosing glass water bottle?

 

Ordinary Glass

Ordinary glass water bottles are mostly fired from high temperature silicon, using high borosilicate heat-resistant glass, which has excellent heat resistance and corrosion resistance. As a green environmental glass material, the glass body is crystal clear, soft and elegant in shape. It is a good companion for tea making and healthy drinking water.

1. Material quality should be pure: glass material is not pure, and there will be lines, bubbles or sand on glass drinking water bottle.

"Stripe" refers to the appearance of stripes on the surface of glass bottles. Rough wrinkles can be felt by hand, and fine wrinkles can only be seen against light.

"Bubble" refers to the small void in the vitreous body formed by encapsulation of air, which can be divided into two types according to the causes of formation: material bubbles and operation bubbles. The bubbles are deep inside the glass and look like small circles from the outside. Operating bubbles are more exposed, some like fish eye protruding, a slight poke will perforate; some like small scars on fruit is also easy to peel off layer by layer.

"Sand" refers to the white granular silica sand embedded in the vitreous body without melting. It also refers to other granular impurities. When sand is embedded in a thicker base, it is difficult to find it. Because the composition of sand and glass is different, the expansion coefficient is different, so slightly collision will break off with the glass, resulting in glass water bottle cracking; sometimes there is no collision, but because of temperature changes, sand will also break off with the glass, resulting in automatic glass water bottle cracking.

 

2. Thickness should be the same: that is, the distribution of glass materials in all parts of the water bottle should be uniform. When selecting, observe the glass water bottle against the light. If the light sensation is the same everywhere, the thickness is the same; if the light and shade are too different everywhere, the thickness is not the same. When selecting, from the outside, the bottom should be horizontal, not sloping or pan bottom; when you flick your fingers around the walls, the glass water bottle should make a pleasant sound.

 

3. The appearance should be beautiful: the surface should be smooth; the gloss of the water bottle should be good; the lid should not be too loose or tight; the shape of the teapot and cup should be coordinated.

 

Double glass water bottle

Double glass water bottles are transparent, not easy to scald, easy to clean, no tea stains, and anti-friction. Set environmental protection, practical in one of the high-quality products. Double glass water bottles, the greatest advantage is thermal insulation. In the middle of the two layers
