Water, neutral and acid solutions, strong acids, acid combinations, chlorine, bromine, iodine, and organic compounds are all very resistant to borosilicate glass 3.3. Even when exposed for extended periods of time and at temperatures above 100 °C, its chemical resistance is superior to that of the majority of metals and other materials.
At temperatures above 100 °C, only concentrated phosphoric acid, hydrofluoric acid, and strong alkali significantly remove the glass’s surface (glass corrosion).

Physical characteristics
Trendglas borosilicate glass 3.3 can withstand a maximum temperature of 500 °C for brief periods of time.
The lowest temperature that may be reached for our glass is around -196 °C. In general, using our glass goods at temperatures as low as -70 °C is advised. Stepwise cooling and heating is consequently advised in practice.
Trendglas German Glass Kettles, (Vesuv 4-Cup, Nova 5-Cup, and Classic 7-Cup Kettle) can be used on gas, and electric stovetops.
Allergy sufferers can use our glass items because they don’t emit any chemicals. Because of its poreless surface, it is simple to clean and hygienic to use. Our glass goods have a wide range of applications, including cooling and freezing (to -35 °C/-31 °F), preparing and serving food, baking, and frying. demonstrating a strong tolerance to fast temperature changes
