The core material of our products is high borosilicate heat-resistant glass, which, unlike ordinary soda-lime glass, has a lower coefficient of thermal expansion and excellent resistance to temperature differences. Even at room temperature, cups chilled in the refrigerator will not easily crack when boiling water is poured into them;They can hold both hot and cold beverages, suitable for boiling water, herbal tea, coffee, milk, fruit tea, sparkling water, and various other drinks.
The material has passed food contact safety testing, is lead-free and cadmium-free, has a smooth inner wall that does not absorb tea stains or odors, and does not yellow or fog after repeated use. They are easy to clean, and most models are dishwasher safe; Single-layered glass cups are completely transparent, eliminating the risk of water accumulation in the interlayer. Long-term use will not result in mold growth or moisture residue, and maintenance is much easier.
The manufacturing process mainly consists of machine pressing and hand blowing. Machine-pressed single-layered heat-resistant glass cups are suitable for large-volume orders, with uniform cup specifications, consistent wall thickness, minimal dimensional errors, stable delivery times, and a significant cost advantage. Available colors include transparent original, smoky gray, amber, and gradient colors; the cup body can be finished with smooth, vertical stripes, hammered, or embossed textures, and the rim can be decorated with gold or silver accents to meet different price points.
