How did it all begin? Why are they so valuable now?

This article will go through some details like a brief history of the cast iron kettle and the current antique cast iron kettle value. Let’s dive in.

Brief History of the Antique Cast Iron Kettle

The antique cast iron kettle has its origins in Japan. The Japanese word for cast iron kettle is Tetsubin, which translates to “iron pot”.

Tetsubins are cast iron tea kettles in Japan with a top handle and a short spout for pouring water. They are used to boil water, and most of them are handmade.

Tetsubins usually have different patterns and details that make them unique. An example of such patterns is the arare. The arare is a bumpy pattern of dots all around the body of the tea kettle.

Other patterns include hada, a rough pattern with an irregular textured surface, and a symbolic motif, which could depict different figures, birds, shapes, or trees.

Nobody is evident on the exact origins of Tetsubin, but there are many guesses as to where it might have originated.

According to the Encyclopedia of The Way of Tea (Genshoku Chado Daijiten), a Japanese illustrated tea encyclopedia, the cast iron tea kettle originated from a water kettle called tedorigama. This kettle was already famous in the 16th century.

Another theory is that Tetsubin was created as the teapot for brewing sencha tea. Sencha was a Japanese loose leaf green tea that was popular in the second part of the 17th century. Tetsubin cast iron tea kettle became famous thanks to the popularity of sencha.

No matter the origins of cast iron tea kettles, what is important is how relevant it became to boil water in Japanese tea ceremonies. The cast iron tea kettle is preferred to the kama, a cylindrical kettle, because of its portable body and short spout, making it convenient for pouring hot water.

Before the cast iron tea kettle became popular in Japanese culture, other kettles were used to boil water for tea during ceremonies. Some of them were made with bamboo, wicker, or wooden handles. However, they were usually ceramic or porcelain.

The cast iron kettle took some inspiration from these kettles but grew to be more popular than them. This is due to a common belief that water boiled using a cast iron kettle tastes better than water boiled using porcelain, brass, or other materials.

Another essential antique cast iron kettle that originated in Japan is the Tetsu kyusu. While the tetsubin is mainly used to boil water, the Tetsu kyusu brew tea.

How the Cast Iron Tea Kettle Is Made

The people of the Tohoku region are known as the creators of cast iron tea kettles like the tetsubin and the tetsu kyusu. This is due to their ancient history, which has much to do with forging iron weapons for fighting.

Most of the iron casters settled in this region and have been there ever since, creating iron cookware, like the iron pot for cooking, the cast iron frying pan for frying, and the iron kettle for boiling water and brewing tea.

In the Iwate Prefecture of Tohoku, some of the best iron casters have made iron kettles for centuries. It takes many crafters more than two years to get the details right. This includes designing, molding, and casting many handmade cast iron kettles.

All cast iron kettle designs start with a detailed sketch. This sketch is done on paper to give an idea of the details the tea kettle should have when it is completed. This sketch also helps them design the mold where the iron pot would be cast.

The mold is a gap where the molten iron is poured and allowed to form. It is made of three parts. These three parts are joined together, and a small gap is left at the top to allow the iron to be poured in for the kettle to form.

The mold’s core is destroyed with each use, but the outer mold can be reused up to three times, depending on the type of tea kettle molded. Any use beyond this would lead to the degradation of the quality of the iron kettle.

Many iron crafters have said that over 70% of the work in making cast iron kettles is building the mold. This is because the mold provides the complete details of a cast iron kettle.

The mold is made of materials with excellent thermal conductivity and heat resistance. Examples of such materials are steel, copper, or type A graphite.

During the creation of the mold, the crafter creates the arare. The crafter does this by putting dots on the inside of the mold so that when the iron is poured, the dents in the mold make the arare form.

Most cast iron tea kettles have 2000 or more dots on their surface. It takes more than three hours to put dents on the mold for a single tea kettle. The more dots, the higher the antique cast iron kettle value.

The mold’s core is coated with charcoal to make it easy to separate from the iron kettle.

When Were Cast Iron Kettles Used?

Cast iron cookware was made in many English blast ovens in the 17th century. Then, in 1707, Abraham Darby developed the technique that made kettles thinner and cheaper than their rivals.

Initially, Darby made cookware with brass, but later, he transitioned into using cast iron. Although the cast iron pot originated from Japan, Darby and the English were the first to mass produce it on a large scale and make it popular in many places globally.
