A freeze glass will keep a drink ice cold for at least 30 minutes.
Once frozen, the glass will chill your drink within 2 – 3 minutes to a temperature between 0°C and -2°C (32°F and 36°F).
A freeze glass can be activated by keeping it in the freezer.
Amsterdam Glass is the patent holder of the special consumer safe and environmentally friendly glass cooling technology.
All freeze glass products are fitted with a special pressure release plug. In case there is any overpressure the valve will depressurize and the cooling liquid will be released. Just another feature we have added to for your safety. The valve is a special one-way valve and therefore makes the freeze glass dishwasher proof.
The liquid between the double layers is consumer safe and consists of only natural liquids. The liquid freezes to -18°C (-0.4°F) when cooled in the freezer. The temperature of the freezer should be between -15°C and -25°C (5°F and -13°F). With this technology the freeze glass will take the heat from the drink and release the cold of the liquid directly to the drink inside the glass. The freeze glass is dishwasher safe and can also be hand washed.
