Benjarong

Benjarong (Thai เบญจรงค์) ware is a kind of painted porcelain in Thailand. The name literally means 'five colors'. The painted decoration usually consists of 3 to 8 colors. For the decoration, repetitive forms, usually geometric or flower-based, are used. A design is usually named after the decoration base name and a background color (for example, Phum Kao Bin on dark blue).

Enamel colors are applied and overglazed, creating a swelling effect over the surface of the piece. The production process is incredibly labor-intensive, as each color is applied individually, and the piece is kiln fired after the application of each color. The firing process brightens the colors of the finished piece and adds to its beauty. Gold is also used in painting the porcelain.

Production of Benjarong is a process known to only small communities of Thai artists which have passed down the knowledge from generation to generation. The artisan who makes Benjarong has to be very skillful and careful. The production process is needs a skilled labor. How the Benjarong is made and how the patterns are painted, are glamorous and all considered as the masterpieces. In the porcelain selection, only white porcelain (Bone China and Royal Porcelain) which had been fired at the proper temperature (1150-1280 degree Celsius) for many hours, are selected. White ware must not have any flaw. After we get all required white wares, cleaning is the next process. During this process, it is necessary to avoid oily surface from sweaty and dirty hand. In drawing process, we use hypodermic syringe or paint brush to draw line. The process begins with drawing the circular guide lines on the Thai porcelain on a turning wheel, which is manually controlled. While drawing on the design, the artist will keep the sample pattern in front of him so he can draw the pattern correctly. The initial pattern drawing is very crucial to how the design will turn out, so it will be done by the well-experienced artist (usually drawn by a master craftsman). This is the reason why the pattern is drawn in very fine lines on each Benjarong. In painting process, there are various colors of paint but basically we use five main colors (black, green, yellow, red and white). The specialized paint for Benjarong needs a skillful painter. The paint is made from mineral colors and must be well crushed and mixed with water in proper ratio. The crushing equipment is ceramic or equivalent material mortar. The paint should not be too thick or thin. If the paint is too thick, it will not be completely fired and the color will not be shown as expected. If the paint is too thin, the color will fade. Also, the paint must not overlap with any line of the other color. At the final stage of painting, the 18 karat gold might be added to the rims in order to make it look glamorous. The next step after painting is firing. Painted wares will be put in the kiln. The spaces between them are 0.5 – 1 cm unless you want the painted wares to touch each other and might get damaged to pattern that painted after firing. The temperature in the kiln is controlled between 800 and 1000◦C and takes about 10 hours firing time. The Benjarong must be put in the kiln five times. After finished firing, the Benjarong will be cooled down; then take it off from the kiln. Once the Benjarong has been fired, it can be seen as three dimensional bubble of paint on the surface, which is the reason why Benjarong is unique. At the end of production, there will a quality control. The slightest mistake in any process would ruin the design and fame of Benjarong. Any mistake is unacceptable. Benjarong supposed to be perfect in every respect. If the mistake is found, it will be sent back to the studio or might throw it away. In fact, this is very rare to happen because during each stage the artists take good care of each individual piece. (Blobiztar Company Limited)
