About Sekishu Kameyama-yaki
Since around the turn of the millennium, we have created many carbonized yakijime vases and beer cups. Carbonized yakijime is a process in which pieces are fired over an extended period of time and discolored during the process, resulting in unique works of art.
We make pieces for wedding receptions, private family parties, senior birthdays, Mother’s Day and Father’s Day celebrations, baby showers, and company founding anniversaries.
|Artifact Name||Sekishu Kameyama-yaki : Ceramic|
Sekishu Kameyama-yaki is a type of pottery that was invented by Kenjoo Sasaki in Hamada City, Shimada Prefecture after he spent decades training on the Aganoyaki Totoki kilns in Fukuoka Prefecture.
Named after Hamada Castle (also known as Kameyama Castle), which fell during the Choshu Rebellion during the Meiji Restoration, Sekishu Kameyama-yaki is produced through unique shaping techniques and uses a variety of overglazes, including cinnabar lacquer, yakijime, akanagashi (red glaze), aonagashi (blue glaze), black enamel, white enamel, and Irabo enamel.
The Traditional Craftsman Profile
While spending 25 years training and researching at Aganoyaki Totoki Kilns Shirakawa House in Tagawa City, Fukuoka Prefecture, learned the secrets of the traditional Aganoyaki glaze.
*Unique shaping techniques are used, as well as a variety of overglazes, including cinnabar lacquer, yakijime chinaware, akanagashi (red glaze), aonagashi (blue glaze), black enamel, white enamel, and Irabo enamel, combined with hard work to create unparalleled works of art.
Creation of a beer cup on an electric potter’s wheel
- 1. Formation
- 1) The clay is stretched to around the potter’s chest-height, then both thumbs are pressed into the center to make an indentation.
- 2)Create a sake cup shape with both hands
*This is the base shape for the finished piece.
- 3)Push up the sides of the sake cup created in step 2), stretching the piece upwards.
*repeat this process 2-3 times.
- 4)Put a spatula inside and stretch until the piece reaches the final size.
*The straight portion on the side of the spatula is used to stretch the inside cleanly,
with the diameter and depth occasionally measured and adjusted.
- 5)Once it reaches the desired size, a fingernail is run along the base to mark where it is to be cut.
*Horizontally pull the cutting thread clockwise to cut it evenly.
- 6)The index and middle finger of both hands is used to raise it and support it at the base.
*Finishing touches are then put on the base, and then shaping is complete.
- 2. Drying
- The piece is left in the shade indoors to dry for several days, followed by drying in the sun.
- 3.Biscuit Firing
- The piece is slowly fired for 12 hours at around 850 degrees Celsius (a low temperature).
*After firing is finished, it’s left out to cool for several days. Pieces that crack, have the bottom drop out, or chip during biscuit firing are disposed of; only the good products are sent to main firing.
- 4.Glost Firing
- Biscuit-fired beer cups are placed into the kiln with charcoal and fired slowly over 48 hours in a stifling atmosphere, a technique known as reduction firing.
The product is left alone until it goes below 100 degrees Celsius (50 degrees Celsius in winter), then it’s finally finished.
*Once glost firing is finished, it cools for several days.
- ●Strict inspection is done, and only the best finish products are sent out to the customers.
*All others are destroyed.
Making the clayThe most important part of making porcelain is making the clay.
When the production process begins, there will always be leftover clay and scrap clay from finishing.
We believe that using every bit of this clay is important.
*The raw earth for the clay is left out in the elements for several months or years to be weathered and enriched.
ElutriationElutriation is a process in which raw earth is dried, crushed, and put in water, then agitated and run through a flow of water over and over again.
The purpose of this is to even up the raw earth particles and to eliminate impurities.
