Kettles are designed primarily to boil water on charcoal stoves or maintain the temperature above the alcohol stove burner. They can also be used on a gas or electric stove (not induction stoves), but ONLY WITH STOVETOP HEAT DIFFUSER (we send diffuser with the kettle) - if you use the kettle without it, it may break immediately, or its lifespan may be reduced significantly. I recommend using lower heat on electric stoves - about 60% of full power (on a scale 6 from 9). I do not recommend using the kettle on an outdoor open fire or placing it directly on hot coals.
The maximum volume of the kettle is approximate, and you need to test how much water will suit you when boiling. The kettle should be filled with about 80% of the water that fits in. When boiling water, keep an eye on how much water is left in the kettle, and only leave it on a heat source if there is enough water. It is also wise to avoid thermal shocks as much as possible. For example, before you pour cold water into the hot kettle, it's a good idea to let it cool for a while. If you need to store the kettle away from the heat source, place it on less thermally conductive pads such as wood, cork, reeds, etc., rather than stone, metal, concrete, etc.
When water boils violently with bubbles in the kettle, give the water some seconds before pouring it out; otherwise, it will not pour well.
While in use, pay attention to escaping steam, which can burn you. For the best possible flow of water while maintaining safety, please direct the hole in the lid to a side so that the steam escapes to the side outside of the handle. The handle may get hot if you boil water in the kettle for a very long time.
After use, it is advisable to leave the lid open to allow the kettle to dry well. Kettles are not fully vitrified; it helps to bring the water to boil faster. They will leak water out, so keeping water in the kettle while not in use is not advised.
