Yes, you can put Chemex on stove. You will need to heat up the water to boiling first before pour over the coffee grounds. Do not put the entire pot on the stove though, as this may damage the carafe. Instead, pour out the desired amount of water into a separate pot or kettle and then heat it up on the stove before pouring it over the coffee grounds in your Chemex. This will ensure that your coffee is evenly brewed and doesn't get too strong or bitter.
