Product quality has been the No.1 objective that GINPO has valued more than anything else since its founding. Based on the tradition and techniques inherited from its forebears, GINPO has improved its product quality while meeting the needs of the times. Under the principle of “Wishing to create happy family meal times by making high-quality ceramic pots, and proposing healthy diets,” we developed our original clay and glaze through our down-to-earth research. We engage in the manufacture of excellent products through integrated production in Japan.
Our work begins with making the best clay and glaze most suited for creating ceramic pots. The raw materials for making pots are selected from around the world. In pursuit of an extremely high-grade petalite, which influences the heat-resistance of products, we import petalite from a mine in Zimbabwe, to which we make a request for special ore dressing. Our clay is made by mixing these raw materials. This original clay lays the foundation for our pots, with a performance capable of enduring temperature changes of up to 650C.
Also, our glaze is made through our original formulation in our factory, in which we use no lead or cadmium, and boasts not only a beautiful finish but also high performance in preventing stains and odors, and easier maintenance.
Based on these original clays and glazes, properties such as high heat-resistance, heat storage and durability are developed, and these raw materials are transformed into GINPO’s ceramic pots, allowing its customers to cook and enjoy highly satisfying meals.
The power of a roller machine and a pressure casting method are mainly used in the forming process. Through our cultivated forming technique, we consistently manufacture highly accurate, stable products. We have also designed the shapes of our products to ensure that the pot is not chipped by coming into contact with other objects.
The glazing and painting on the pot are conducted both by machines and manually, through various methods suited to the respective models. Above all, the painting for the Hanamishima and the Kyomishima, whose designs are said to symbolize GINPO’s “Donabe”casserole pots, requires a delicate touch. GINPO’s products are finished by the skillful handwork of its craftsmen.
The firing, the final manufacturing process for our products, is performed in a brick tunnel kiln approximately 60 m long. While a sagger on a cart is put into the kiln from one end and is slowly maneuvered through the tunnel to the exit at the opposite end, the products undergo continuous firing, during which pre-heating, firing and cooling are applied. A computer manages the firing process in order to finely adjust the temperature, so that each product is fired at the appropriate temperature over 24 hours.
We engage in the manufacture of our products daily, while wishing to be involved in the “diets and lifestyles” of our customers, and to be able to make these people feel both physically and mentally richer through our involvement. To this end, high-quality and user-friendly designs are indispensable.
Our approach toward product quality has been handed down from the founder. We maintain the performance and durability of our products at a higher level through integrated production management, through an in-house process from the selection of raw materials to the mixing of clay and of glaze, forming, glazing, firing and inspection. Constantly conducting research, we will improve the process every time better raw materials, and better mixing styles and/or manufacturing methods are found.
The president himself is involved in product design. Keeping with the concept of ceramic pots and tableware that complement the food”, we come up with ideas for our products while visualizing scenes of foods arranged in and on our products, in which our pots and bowls do not spoil the appearance of the foods but impart long-lasting attraction. Also important for daily use is user-friendliness.
Adding the essence of the times to its heat-resistant ceramics, which is its strong specialty, Ginpo Japan will continue to engage in the manufacture of products designed to make your diet richer and more colorful. We would be delighted if our customers could enjoy wonderful times with GINPO’s products.President Tetsuya Kumamoto
