项目摘要

This study attempts to clarify the merits and demerits of both simple method of CO_2 molds and the method of lost-wax mold which can faithfully express the touch, and to develop a bronze casting method by the combined use of both of them.1. Process of molding・ Process of bronze casting in CO_2 molds and its feature・ Process of bronze casting in lost-wax molds and its feature2. Bronze casting by the combined use of CO_2 mold and lost-wax mold3. Production of relief sculpture (bronze casting) by the combined use of CO_2 mold and lost-wax moldThe characteristic feature of bronze casting in relief sculpture by the combined use of CO_2 molds and lost-wax molds is that wax combustion takes only ten minutes with blow pipe, while it takes twelve hours with kiln for burning-out. Compared with complete lost-wax molds, this method is a little inferior in the quality of reproduction of the original touch. In spite of that fact, however, I believe that this method is the most appropriate for the bronze casting practice at teacher training college. In addition, in making molds we can greatly shorten the time by adopting the simple method with CO_2 molds. The problems of having no undercut and piece mold, which are the demerits of CO_2 molds, can be solved by incorporating the process of re-sculpturing wax model. The experience of using various materials is valuable for students who are to be art teachers. I would like to propose introducing bronze casting practice in the field of sculpture instead of unchanged materials of plaster or F R P (Fiber Reinforced Plastics).

本研究试图厘清简易CO_2铸型法与失蜡铸型法的优缺点，并发展出两者结合使用的青铜铸造法，以忠实表现触觉.铸造工艺·CO_2型铸造工艺及其特点·失蜡型铸造工艺及其特点2. CO_2型与失蜡型组合铸造青铜件3. CO_2型与失蜡型结合生产浮雕（青铜铸件）CO_2型与失蜡型结合生产浮雕青铜铸件的特点是：用吹管烧蜡只需10分钟，而用窑烧蜡需12小时。与完整的失蜡模具相比，这种方法在再现原始触感的质量上稍逊一筹。然而，尽管如此，我认为这种方法是最适合师范学院青铜铸造实践的。另外，在模具制作中，采用CO_2模具制作工艺简单，可大大缩短模具制作时间。通过对蜡模进行二次造型，解决了CO_2模具无咬边、无片模的缺点。使用各种材料的经验对于即将成为艺术教师的学生来说非常宝贵。我想建议在雕塑领域引入青铜铸造实践，而不是一成不变的石膏或F R P（纤维增强塑料）材料。
