The main material of high borosilicate tea cup is high borosilicate glass, which is melted at 600℃ during production, has no bubbles or impurities inside, and has a light transmittance of >92%. It uses float forming technology and has a smooth surface and is stain-resistant. The main performance of high borosilicate glass is reflected in the thermal expansion coefficient of 3.3×10⁻⁶/K (extremely low), instantaneous tolerance of temperature difference range of -30℃ to 150℃, fracture strength more than 3 times that of ordinary glass, and acid and alkali resistance (pH 1-14). It is precisely because of some of its characteristics that we also name it borosilicate glass 3.3 in international standards. Its appearance provides convenience for safe drinking and durable use. Not only tea cups, but also beverage cups and water cups are mostly made of high borosilicate material.
As the mainstream tea cup of the contemporary era, there are many styles of high borosilicate tea cups, covering functional design and aesthetic innovation, which are worth having:
Insulation and anti-scalding structure: The wooden sleeve in the middle of the cup wall has the effect of insulation, which is not hot when holding, and is suitable for boiling water and cold drinks;
Side handle anti-scalding cup: The handle is designed on one side. When drinking tea, you can easily avoid burns by holding the handle with your hand. This is a more ordinary tea cup, but it is more common, and it contains extraordinary simplicity;
Hammer texture cup: The surface is hand-hammered with texture, and the light and shadow refraction enhances the visual layering and improves the tea tasting experience;
The above tea cups have different specifications and sizes, and you can choose according to your own preferences.
The characteristics of high borosilicate tea cups are summarized, mainly including its physical properties, safety standards, and usage advantages:
Strong heat resistance: can withstand instantaneous temperature difference from -30℃ to 520℃, and the thermal expansion coefficient is only 1/3 of ordinary glass;
High stability: the anti-fracture strength is 3 times that of ordinary glass, the breakage rate of high drop is ≤5%, and the scratch resistance is excellent;
Food grade material: the ingredients contain ≥80% silicon dioxide + 12%-15% boron oxide, lead-free and cadmium-free, and the amount of heavy metal precipitation is far lower than the national standard;
Easy to clean: the surface is smooth and hydrophobic, the tea scale residue is 62% lower than that of ceramic cups, and the bacterial growth rate is reduced by 80%;
Excellent optical performance: light transmittance>92%, the color of the tea soup is clearly visible, and aesthetic processes such as hammer pattern can be selected to enhance the visual level.
Borosilicate glass tea cups come in a variety of specifications and models, and can be customized according to your needs.
