The large tea glass: 1 litre, heat resistant, with tea infuser
A litre of tea in a single glass: the borosilicate HydroGlas handles temperature changes, which makes it a full tea glass – open, without a lid, without plastic.
Borosilicate glass takes boiling water
Borosilicate glass barely expands when heated, so it copes with big temperature jumps. You can pour boiling water straight in without harming the glass – the same material used in laboratories.
Brew loose tea right in the glass
The wide opening gives loose leaves room to unfold completely. You watch the infusion develop and lift out the infuser as soon as the colour is right – no decanting, no second vessel.
Stainless steel tea infuser to go with it
The precisely fitting stainless steel tea infuser costs EUR 3.90 and hooks safely onto the rim. Together with the 1-litre drinking glass it makes a complete tea set for your desk.
Frequently asked
Can you pour in boiling water?
Yes. Borosilicate glass withstands the temperature change. Don't put the hot glass straight onto a cold stone surface and hold it by the upper rim.
Is the HydroGlas a water bottle?
No. The HydroGlas is a 1-liter drinking glass made of borosilicate glass for home, office and the dining table – not a portable bottle system, no lid, no plastic.
