[wood oil finish]

× Things you shouldn't do ×
・Put it in the machine. microwave, dishwasher, refrigerator, etc.
・Do not place in places exposed to direct sunlight or air conditioning ・Do not leave in water ・Wipe dry immediately after washing dishes

When placed in an environment with strong dryness or temperature changes, or when wet or dry, the wood may breathe, expand and contract, causing warping and cracking.
It returns when it dries, but often not completely.


△ Things to avoid △
・Dishwashing detergent removes oil strongly and may remove the oil coating film of the oil finish. If it is very dirty, we recommend using it, otherwise it is recommended to wash it with warm water and a sponge or acrylic scrubbing brush.
・Curry, heated tomatoes and eggplants, etc., may cause color transfer. If you continue to use it, it will become familiar, but if you are concerned about it, please avoid it. Please be careful, especially curry, as it is easy to smell.
・The same goes for oil stains. However, it has the property of absorbing oil and forms a film of oil, so there is nothing wrong with the amount of film that can be formed. If the stain sticks to a part of it, it may bother you, but if you spread it out and spread it, the whole color will become darker and deeper and you won't notice it, so I personally recommend letting it absorb (of course it's edible). oil only.)


＋ Care ＋
If the oil content disappears during use, or if you are concerned about it, sprinkle some cooking oil at home (olive oil, linseed oil, walnut oil, etc.) and wipe it with a tissue or piece of cloth to let it absorb. Let it dry for half a day or a day, then wipe it off again with a dry cloth. The oil will adhere to the surface and form a coating film. The more this coating film is, the stronger the surface becomes.


◎ How to enjoy growing ◎
Personally, I recommend growing it by adding more and more oil to it while keeping in mind to prevent the X from warping. Unlike vessels made from other materials, it grows deeper and deeper, and is more fun to use than keeping it in new condition.
I personally wash the dishes with lukewarm water, and when I use a lot of oil, I wash them with a natural dishwashing detergent such as soap detergent. I dare to use it without almost doing maintenance. As I mentioned earlier, the oil coating is good for wooden plates, so when I serve oil-based pasta, I use it so that it blends in with the whole before washing. (Because oil makes the color deeper and more pleasing. This is a personal preference.)


* important point *
Regarding warping, it is often said that "wood is alive", but it breathes and expands and contracts according to changes in the environment. Therefore, warping is not 0 unless it is hardened with urethane coating. We exclude items that warp too much at the time of shipment, but even items that are not warped will inevitably warp to some extent as they are used. We are selling it because it is common to all oil-finished wooden plates and there is no problem for everyday use, but please avoid it if you are concerned about it being stiff.

[Wood/Bamboo wood grain finish (unpainted)]

There are some products with a bare wood finish (unpainted), such as products that make use of the texture of old wood and products that do not need to be washed frequently.

Please consider that the handling and precautions are almost the same as the oil finish, and that it is weaker than the oil finish. Therefore, please refer to [Wooden Oil Finish] for basic handling.

The difference from an oil finish is that oil tends to cause conspicuous stains.
If you apply oil to the unpainted finish, it will be an oil finish.

【lacquerware】

× Things you shouldn't do ×
・Scratching or shaving with a hard brush or metal with a sharp tip. The lacquer coating will peel off.
・Pour hot water directly. Color may change to whitish.
・Soak and wash. Lacquer is also water resistant, so you can leave it in water for several hours without any problems, but please avoid soaking it for a long time.
・Put it in the machine. microwave, dishwasher, refrigerator, etc.


△ Things to avoid △
・Immediately wipe off the water after washing the dishes. Depending on the color and application method, water droplets may remain.
・It is not strong against UV rays, so it is better to avoid storing it in direct sunlight.


＋ Care ＋
・Wipe with a dry cloth after washing, or even when not, to bring out the luster.


◎ How to enjoy growing ◎
・Do not keep it away and use it every day. It is in good condition for lacquerware as it can be touched by hand and air.


* important point *
・When washing, use a sponge or acrylic scrubbing brush. You can use detergent.
・A lacquerer (lacquer lacquer craftsman) once said that lacquer is treated in the same way as humans. It's very easy to remember, so I hope you can refer to it. "It hurts when rubbed with a hard brush" and "It gets hot when hot water touches it directly".

[Forged knife]

× Things you shouldn't do ×
・After washing, leave it wet without wiping off the moisture. The blade will rust, and the wooden handle will lead to mold and cracks. If you pay attention to this point, it will not be particularly prone to rust or difficult to handle and maintain.


△ Things to avoid △


＋ Care ＋
・Sharpen by yourself or with a sharpening service such as a sharpener. You can also ask the craftsman who made it, so if you wish, please contact us.
・If there is rust, use a commercially available rust remover. Among them, the eraser-type rust remover is recommended because it is easy to use and there is little risk of damaging the blade.

・Use it every day. The color of the wood will also deepen.

[Indigo dyeing]

× Things you shouldn't do ×
・Wash separately, especially for the first few times. Color may transfer to other laundry.
・It is particularly vulnerable to friction, so if it touches or rubs against white fabrics, the color may transfer.
・Do not store in the folded state for a long time while exposed to light (including not only sunlight but also lighting). Sunburn marks will remain on the creases. When storing the product in the same condition for a long period of time, keep it away from light.
・Please refrain from using a dryer, bleach, or fluorescent brightener.


△ Things to avoid △
・Sun drying. Fading may occur.


＋ Care ＋
・For the first few washes, please separate to prevent color transfer, and once the possibility of color transfer is gone, you can put it in the washing machine and wash it with other items. There is a possibility of color transfer due to friction during washing, so it is better to put it in a net.

[Natural dyeing]

× Things you shouldn't do ×
・Do not store in the folded state for a long time while exposed to light (including not only sunlight but also lighting). Sunburn marks will remain on the creases. When storing the product in the same condition for a long period of time, keep it away from light.
・Please refrain from using a dryer, bleach, or fluorescent brightener.


△ Things to avoid △
・Sun drying. Fading may occur.


＋ Care ＋
・In the case of vegetable dyeing, the process of mordant is included, so the possibility of color transfer is not as high as that of genuine indigo dyeing. You can put it in the washing machine normally and wash it with other clothes. (For dark colors only, it is safe to separate and try while observing the situation.)

× Things you shouldn't do ×

・Do not store in the folded state for a long time while exposed to light (including not only sunlight but also lighting). Since the color will be darker where the light hits it, there will be a difference in color between the place where the light hits and the place where it does not.
・Please refrain from using a dryer, bleach, or fluorescent brightener.

・If you touch metals such as iron in a wet state, the same phenomenon as mordant may occur and discoloration may occur. (stainless steel is fine)

・In the case of vegetable dyeing and natural indigo dyeing, the color fades or fades due to light, but in the case of persimmon tannin dyeing, the color becomes darker when exposed to light. Of course, it doesn't get darker all the time, but the color may change, especially during the first period of use.

【iron kettle】

・Do not leave hot or cold water on. It will rust. Pour off and empty each time. (If you continue to use it and the hot water scale is firmly attached, it will be less likely to rust.)
・The condition that is not completely dry also leads to rust. If you boil it and pour it out immediately and open the lid, it will dry with residual heat. If it has cooled down and there is no residual heat, boil it for a little while and evaporate the moisture with heat. It takes less than 10 seconds, so be careful and keep an eye on it. (If you continue to use it and the hot water scale is firmly attached, it will be less likely to rust.)
・Do not wash the inside of the iron kettle with detergent or rub it with a scrubbing brush.


△ Things to avoid △
・Although it depends on the shape of the iron kettle, in the case of a gas stove, the fire contains a lot of water, so if the fire covers the sides, it may turn red. If you are concerned about it, please use it on low heat so that it only covers the bottom.


＋ Care ＋
・When rust appears and you are worried about the metaliness of the hot water → Put sencha in a tea bag and boil for about 30 minutes. The chemical reaction between the tannins in the sencha and the iron content in the tetsubin will make you feel good. When the turbidity like rust and metaliness disappear, you can use it as it was.

・Use it every day. It has hot water scale, is hard to rust, and grows.


* important point *
・Since it is made of iron, it will rust to some extent. If you don't mind the taste, you can use it.
