The market of silver precious metal clay (PMC) is promising as its application for agile metal craft. The property of suitable hardness and shrinkage as well as environment-safe is strictly required as people make the final product with bare hands. We propose a silver PMC with new organic binder made of palm oil, glycolic acid and water. Then we prepared disk specimen of our proposed PMC and well-known commercial PMC. We investigated the hardness, weight change, linear shrinkage, density and micro structure evolution with sintering temperature of $700{\sim}900^{\circ}C$ ($50^{\circ}C$ gap) for 15minutes. We confirm our proposed PMC has suitable property for craft product comparable for commercial PMC, and the optimum sintering condition is $850^{\circ}C$-15minutes for metal craft application.

The design methods using patterns have been used in various design fields. Both utility and results have also developed a lot, so that patterns occupy an essential parts in designs. Patterns are often used in various techniques in designing ornaments. However, both time and excessive effort concentrations restricted ornaments designs due to the nature of the craft production techniques by repeated patterns. Therefore, in this study, the traditional craft methods are combined by using computer programs in the applications, repetitions, arrangements of patterns for the manufacturing of ornaments.

The Fourth Industrial Revolution has emerged, and technologies of various industries are being converged, compounded, or clouded computing, mobile, or big data. The emergence of a variety of skills and new jobs to match them is bringing the public out of the education and occupation of traditional metal crafts. In this change, craft education should find and study the education method suitable for the present times, and apply it to the educational field to raise public interest and revival. To this end, we will investigate the cases of education in other industries where new materials or technologies have been introduced, and use them in education of traditional metal craft techniques. In addition, we will investigate various cases and features of 3D printing technology and use it for education in craft techniques that have limited time, space and resources.

The Baekje Gilt-bronze Incense Burner which was excavated in an ancient temple site in Neungsan-ri, within the City wall of Buyeo-Gun on 23rd December 1993, was a quintessence of the Bakje Arts that people could not have imagined until that time. The Baekje Gilt-bronze Incense Burner transcended 1400 years of time and space. The censer that finally came up to us delivered a kind of a powerful message to us. The power was so strong and mysterious that as if an ancestor who had been sleeping in the grave with a great silent had woken up and become alive to tell us something very precious. Baekje Gilt-bronze Incense Burner, unlike any other existing artifacts, might have a possibility that could provide an insight of the ancients' psych who once lived on our land. This kind of view from several archaeologists, therefore, made our hearts be filled with excitement and flutter. We call 21st century as an era of culture. This era requests that the culture needs to be ethnical but the culture also needs to go beyond that ethnic. In other words, a culture without an ethnic cannot exist, and a culture that puts an ethnic the very first before any other things cannot exist as well. Regaining our identities first and then embracing and harmonizing various cultures can be an wise way overcoming above problem. Hence, through this study, I intend to recognize characteristic of plasticity for Baekje Gilt-bronze Incense Burner, understand the world of Baekje people's spirit and thus provide an opportunity to shed new light on the Baekje Arts. By doing so, I would like to publicize a metal craft of Korea to the world. I also try to seek for an identity of Korea's craft culture which is receding and find a direction for the Korea's craft.

The effect of betatizing temperature on microstructure and transformation characteristics in a Cu-AI-Ni based pseudoelastic alloy fabricated by heated mold continuous casting by using metallography, XRD and calorimetry. The microstructure of cast rod betatized at $600^{\circ}C$ revealed a ${\beta}_1$ parent phase and a ${\gamma}_2$ phase precipitated along the casting direction. When the cast rod was betatized at the elevated temperature above $600^{\circ}C$, the ${\gamma}_2$ phase is completely dissolved into the matrix so that the volume fraction of the ${\gamma}_2$ phase was decreased. The parent phase was stabilized by betatizing at $600^{\circ}C$. However, the ${\beta}_1$ parent phase was transformed to both ${{\beta}_1}^{\prime}$ and ${{\gamma}_1}^{\prime}$ martensites with increasing betatizing temperatures above $600^{\circ}C$, while $M_s$ and $A_s$ temperatures were decreased. The stress-strain curves for compression test were not same with betatizing temperature; the stress-strain curves of the specimen betatized at $600^{\circ}C$ and $700^{\circ}C$ were linear but those of the specimen betatized at $800^{\circ}C$ and $900^{\circ}C$ were not linear.

There are symbolicity and special meaning in the materials which are supposed to be used metalcraft from ancient to present. These are basical resources of hermeneutics and play a role as moaning elements. Generally, the precious Cold and Silver are mainly to be used with precious stone. But recently, ordinary materials like glass iron aluminum has begun to be used with them. Several artists are intentionally using them, and special skills which could be revealed by only the matherials are developing by them. In these skill, there are original material's texture and character of matter are looking like other matter. Well, special skills are adapted in these matters to magnify the possibility of expression, the originally codified meaning resources are disturbed. For example, The metal craft artist June Schwarcz is using the skills of electroforming, copper foiling, enameling, wire brush patina, fine wires fusing, etc. He is doing abstract forming and making various textures. And his works are very big size, and done by the skills of painting and sculpture. The outer form is very structural, special touches of the artists are heterogeneously mixed with the symbolic abstract expressionism color field. Further, there are mixed with Primitive original life atmosphere, Medieval ornamental aspect, Minimal, and Chaotic aspects. The meaning particles of these aspects are directly/indirectly joined but special skills and basic material languages are mixed together, the originally codified material language are disturbed. These disturbed material languages are becoming optically special effect and be illusion. It is making expressing way of tile metalcraft more fertile and be infinite.
