Iron kettle by Azmaya

Made in Iwate, Japan
Iwate has the about 900 years of tradition for casting.

The surface of inside is pretreated against rusting by heating over 800 degree after casting. This makes a oxidised film to protect the iron surface. The outer surface is pretreated by burning with camellia oil and tea incrustation’s liquid one after the other repeatedly.

However soon or later, this iron kettle just as any other iron products will becomes rusted. Please read this instruction carefully before use.


It’s usable on direct fire, ceramic glass cooktop, and halogen. Only large size (1.5L) is inductions heating /200V tolerant. SMALL SIZE (1L) IS NOT.

  • After rinsing the inside of kettle, pour the water up to 70% of full content and boil 2-3 times to make inside clean.

  • To avoid boiling over, always fill at maximum 70% of full capacity.

  • When heated, the whole surface becomes extremely hot. Use a thick dried cloth to hold the handle and the cover.

  • Do not touch anywhere of the kettle with the bare hand. When pouring the boiling water, hold the cover with a thick dried cloth to avoid sliding down.

  • Pour all water completely out of the kettle and leave the cover open to dry with the remaining heat. If any drop of water is remaining, it will cause a rust and in this case, heat the kettle until the water evaporates completely.

  • Do not rub any surface. If it gets a dirt, wipe it with a soft cloth. Rubbing takes away the film of scale which refrains from rusting.

  • Do not heat the kettle without water. It may cause break and rusting.

  • Do not cool down suddenly the heated kettle with cold water. It may cause cracks and break.

  • Pay attention the underneath. The back side of kettle is rough and it might make scratches on a table or any other surfaces of furniture.

  • Falling down or hitting hard might break the kettle.

  • Keep out of reach of Children.

  • Any accident caused by using this kettle is solely user’s responsibility. Neither the producer nor the retailer take any responsibility.


After making sure that the kettle is completely dry, wrap it with a soft fabric and place it where there is no humidity. Leaving it in a humid place might cause a rust.


Every time boiling the water, the calcium and the mineral in water become attached to the inside of kettle. It’s white and this film of minerals protect the surface from rusting, so do not rub it away. To make this white film attached as soon as possible, use the kettle everyday in the first month. Cooking mineral water with high calcium rate with low to middle heat makes this white coating faster.


Nevertheless, just as any other iron product, this kettle will get rusted one day. Then, follow the steps below:

  1. If the kettle is rusted very hard, brush inside with a soft brush. Normally any brushing or rubbing is not recommend as the coat protecting the surface will be taken away. So make sure to brush only when it’s rusted really hard.

  2. Rinse inside and fill up the water to 70% of the capacity and put a small cup of green dried tea leaves into water and boil them together.

  3. After boiling, lower the temperature and cook for about an half hour.

  4. Stop heating and leave the kettle as it is about for 10 hours. The water becomes black as a reaction of the tannin from tea leaves and the iron from kettle. This makes new coating again.

  5. Rinse the kettle and boil the water again.

  6. If the water is already clear, use normally again and if not, repeat the procedure of no. 5. It may remain the smell of tea leaves for the first couple of times, but it will be away.


Wiping with a green-tea-soaked soft cloth is most effective to make the outer surface beautiful turn of shine and you can enjoy the beautiful ageing.


If you need a repair, it is possible to send back to the producer, but please be aware that transport and any other additional cost happening for sending to Japan will be at buyers cost.
