You can put the water in the teapot on the cooker to bring it to the boil as it is made of heat-resistant borosilicate glass. Make sure to heat the pot evenly and do not add cold liquids to avoid damage.

Unfortunately, it's not possible to only deliver the glass part.

Product dimensions : 17.8 x 12.7 x 14 cm Unfortunately we do not have any other dimensions.

EXTRACT: Borosilicate glass is very robust and heat-resistant. It can also withstand temperature fluctuations, such as when pouring hot liquids, without fear of deformation. Because of this, it can also be used for cooking and baking on the cooker, in the oven and in the microwave. For example, it is suitable as a material for kettles, baking dishes, oven trays and even pans.

Why the question: Haven't found anything at the manufacturer. Just thought someone had already tried it. I don't have a kettle myself and it's still practical in the microwave. The question is whether the handle gets hot or conducts heat. I have both with cups, one that doesn't get hot and the other so hot that you can't hold the cup by the handle. Otherwise, I'll ask the manufacturer. Thanks to the community! :)

I would say 1.2l. My 1 litre kettle does not fill up the jug, there would be room for about one more cup.
