Can I put hot water in my RJ3 Cold Brew Maker?


Our Cold Brew Maker glass carafe is made of highly resilient borosilicate glass, meaning it can withstand temperatures from -30℃ ~ 180℃ without a problem. This property also means that the RJ3 Cold Brew Maker is microwave safe and dishwasher safe. However, we do not recommend putting it on an open flame to boil water or brew tea/coffee.
