Akae porcelain, an artistic Japanese traditional overglaze ceramic typically known for Kakiemon-style ware, has fascinated porcelain lovers around the world for over years because of the graceful red color displayed by akae that matches so well with white porcelain bodies.
In this work, we clarified the factors that control the color of akae and those that are conventionally controlled by artisans based on empirical experience. Inspired by a recent particle-design method, we also developed a practical facile process to prepare red paints that yields high-quality akae. Various akae samples were prepared from a combination of lead-free alkali borosilicate glass frits with different particle sizes and hematite powders with differing dispersibilities.
In addition, we developed a process for preparing high-quality red paints that uses a large-particle frit powder and a strongly aggregated-hematite powder, both of which are easily obtainable. The red paint composed of frit, hematite, and the solvent is mixed until the paint is drying. By adding more solvent and repeating this process three times, we obtained high-quality akae with a higher reflectance value than for the akae prepared from a frit with submicron-sized particles and weakly aggregated-hematite powder.
The good dispersibility of these particles leads to high-quality akae. Figure 1. Micrographs and particle-size distributions for frits and hematite. TEM images for d M- and e S-hematite powders.

In the early 17th century, the Japanese artistic red overglaze ceramic ware akae was first created by Sakaida Kakiemon, who was instructed in this new skill, by hearsay, by a Chinese person living in Nagasaki, Japan.
Since then, this overglaze has become extremely popular with porcelain lovers all over the world. In particular, Kakiemon-style ware was exported to Europe in the 17th and 18th centuries, enthralling the royalty and aristocracy of the time. The traditional Japanese akae is generally prepared as follows: 10 the red paints are prepared by mixing and crushing for a long time e. The result is an akae work, which is a composite in which hematite particles are dispersed in a glass layer.
Hematite has been widely used as a red pigment since prehistoric times. Recently, hematite has become an important material in nanotechnology because of its potential use as a catalyst, gas-sensing material, electrode material for lithium-ion batteries, and photoanode material for photoelectrochemical water-splitting reactions.
In the early 18th century, a high-quality red pigment Fukiya bengala was developed in Japan and used by pottery producers throughout Japan, such as in Arita, Kutani, and Kyoto. The synthesized powders are expected to see use as red colorants for akae porcelain, because they exhibit a high-quality, thermally stable red color.
The use of red paints commonly composed of glass frits that contain lead and have low melting points, is strictly regulated because lead is harmful to human health and to the environment. Therefore, many areas in Japan have worked on developing lead-free glass frits to produce porcelain. However, the current lead-free frits do not yield high-quality akae , and overcoming this problem to obtain improved lead-free frits is strongly desired.
In addition, the color of akae depends significantly on the particular porcelain producer, despite different producers using the same lead-free frits.
In fact, each porcelain producer uses their own techniques developed by master potters, and these are passed down from generation to generation through an apprenticeship system. With their special skills acquired after so many years of experience, as well as a great deal of trial and error, the master potters create artistic works. Unfortunately, their techniques and skills are poorly documented in most cases, making it very important for the porcelain industry to clarify the coloring mechanism of akae and the underlying chemical reactions that take place during its production.
In one of the few studies on the coloring mechanism in akae , Takada focused on particle size and dispersibility of hematite powders and revealed the following facts by making and analyzing akae samples which are prepared by using a leaded frit and hematite powders of various particle sizes and dispersibilities.
The red color depends on the hematite-particle size, the dispersibility of the hematite particles, the thickness of the glass layer, and the solubility of hematite with respect to glass. The red color becomes bright and vivid when the hematite-particle size is small and well-dispersed, when the glass layer is thin, and when the solubility of hematite is low. Recently, although some detailed investigations have been done into akae of the old Imari and Chinese porcelain from the historical viewpoint by using a state-of-the-art analytical method, the essential coloring mechanism of akae is still not clear.
We believe that scientific studies on traditional technologies can provide artists with new inspirations and chemists with new concepts for creating novel functional materials. A comprehensive study of akae , including hematite red pigments, glass frits, the method of preparing red paints, and the mechanism behind the color of akae , is warranted because akae is a composite made of glass layers and hematite particles.
Such a study should describe a method for easily controlling the color tone of akae. However, no such study on akae has been reported since Takada in , 10 and, to the best of our knowledge, no study exists detailing how to prepare akae with lead-free frits. In the present work, we prepared akae samples with lead-free frits that, due to concerns for human health and the environment, will soon be widely used in the porcelain industry. We also discuss the factors that control the color of akae and develop a simple method to prepare red paints for high-quality akae.
In particular, we focus on particle size within the frit and the particle size and dispersibility of hematite powders. The akae samples thus prepared were analyzed mainly by light and electron microscopy. Based on this analysis we designed a facile and practical method to prepare red paints and composite particles for hematite and frits, from which we obtain high-quality akae.
Experimental Section. We prepared two types of hematite powders with the same primary particle size but with different particle-size distributions. Based on our previous report, 9 we synthesized hematite powder using the polymer complex method. M-hematite was ball-milled ANZS, Nitto Kagaku in ethanol at 80 rpm for 65 h in a high-density polyethylene container mL and g zirconia balls with 5 mm-diameter. The slurry was adjusted to 1.
The volume ratio of air, zirconia balls, and slurry was Three kinds of frit powders with different primary particle size were prepared as follows: We used a commercially available alkali borosilicate glass frit Kyo Muen Daigusuri, Kyoto Iwasaki containing small amounts of ZnO. The chemical composition of the frit is listed in Table S1 in the Supporting Information. L-frit was ball-milled in ethanol at 80 rpm for 90 h in a zirconia container 1 L with 1.
The powder thus obtained is called a small-sized frit S-frit. SEM images for frit powders were obtained as compositional images in backscattered-electron BSE mode. For TEM measurements, a powder sample was suspended in ethyl alcohol. The suspension was dropped onto a copper grid coated with a carbon thin film having holes with several micrometers diameter Nisshin EM and then dried.
The general procedure for preparing akae samples is as follows: By using a porcelain mortar , Ishikawa Kojo , a hematite powder, a frit powder, and a green tea solution were mixed at a weight ratio of We used a green tea solution as a dispersing agent because the tannic acid in green tea is known to be a good dispersant.
Various combinations of hematite and frit powders were examined. We also developed a precombination treatment, which we apply once or three times for combining L-frit and M-hematite. This operation was repeated either once or three times. The slurry was mixed again by the porcelain mortar for 10 min. Subsequent operations are the same as described above in the general procedure. The color measurements were done at least three times on the red overglaze enamels in places where the substrate was not visible.
The measurement window is round with a diameter of 3 mm. Results and Discussion. Figures 1 a—c show SEM images for as-obtained and crushed frit powders.

Any object is made up from a collection of materials manipulated in a certain way. A textile requires fibers; a ceramic pot certain minerals. The techniques to convert substances or materials into an object include mechanical weaving or shaping or chemical fulling, firing operations.
Interestingly, not only do most of these sectors have roots in antiquity, but they also share a number of common general processes. For example, all are fundamentally based on the use of naturally occurring raw materials in powder or fine particulate form which are transformed by heat into the desired products. Therefore, despite the range of processes and products encompassed in this group, these common processes allow a common overview of potential health hazards associated with these industries. Since the various manufacturing sectors are composed of both small, fragmented segments e. There are common safety and health hazards encountered in manufacturing of products in these business sectors. The hazards and control measures are discussed in other sections of the Encyclopaedia. Process-specific hazards are discussed in the individual sections of this chapter. Most of the industrial manufacturing processes receive dry solid raw materials in bulk form or individual bags.
