China and South Korea jewelry design technical report will be held at the Shanghai Jiao Tong University. This is an in-depth exchanges between the two countriesjewelry field. The report will be jointly organized by Shanghai Jiao Tong University and Seoul municipal university. The report covers many fields of jewelry design andgemological Research (the main content topic, report and report attached).
Present situation and development of green jewelry design industry
Seoul Research Institute of Jewelry City University of Seoul
Environmental design (Green design) is a concept from the second half of twentieth Century began to mention. Its purpose is to produce and dear environmentalproduct reuse improve resource. About the circulation (Recycling), mainly throughrepeated use, repair, re manufacturing, recycling design means; and "cut" is the dominant design for energy saving. With the popularization of the concept of green,in the field of jewelry design also has many aspects can be a symbol of this idea. In order to understand the current status and future prospect is better, for the related research.
The South Korean modern metal arts and crafts jewelry design history for 40 years
Seoul Research Institute of Jewelry City University of Seoul
In the development history of Korean art, South Korea’s metal craft and jewelrydesign after 1970 made leaps and bounds. From the beginning of 1970, the first batch of overseas returnees in metal technology achievement worthy of attention.After 1980, in some excellent noble University, also opened a modern metal craftand jewelry design professional. So far, a long reputation. Not only has made the development of modern technology of metal and jewelry design, interior design,CAD/CAM design, green design and other related fields have been introduced.
Research does not change color silver jewelry
City University of Seoul
In order to improve the current main jewelry with silver (sterling silver) easily discoloration problem, in which the addition of 5% Ge, In, the results of its corrosion resistance, casting, the hardness is improved to a certain extent. The alloy to produce the actual products, more than 6 months, with no sign of discoloration of the show, the alloy is feasible in jewelry manufacturing.
Cubic zirconia discoloration project development
City University of Seoul
In order to improve the cubic zirconia by melting method for the synthesis of color,at a certain temperature to the vacuum heat treatment. With the increase of the vacuum heat treatment time and temperature, 7 cubic zirconia prepared graduallyfaded and eventually become black. This completely changed to cubic zirconiablack re using acetylene torch to heat treatment will be 10 minutes to change back to the original color. In this project the cubic zirconia is processed into the desired color. The new project with high value of cubic zirconia, and need less energy toenergy saving and environmental protection. In this study, cubic zirconia with thisnew engineering treatment made sample.
The development of synthetic diamond jewelry design engineering
City University of Seoul
The diamond and natural diamond has the physical and chemical properties of the same. Recently, with the development of high temperature and high pressureequipment, high temperature and high pressure treatment of diamond and growth technique has a great development. So far, mainly in high temperature and high pressure conditions, the temperature difference of GE crystal growth method for the synthesis of diamond. At the same time synthetic drilling and natural diamondhas the same nature, traditional identification method is no longer applicable, only the use of FTIR, UV-VIS-IR, PL etc. optical instrument, in order to effectively identify.
Research and application of high frequency sputtering coating on the gem in
Wang Jiajun of Shanghai Jiao Tong University
The Gemological optimization and identification method has been a popular topic.Jewelry equipment laboratory using coating means "new RF sputtering method" in a variety of sapphire crystal surface is plated with two zirconium oxide film, so as to improve the gem surface gloss, repair and sapphire surface minor scratches, and using the Mohs hardness method, the reflectivity contrast method and element analysis method (SEM&EDS) for surface analysis of coating gems, characterization of gem sample table gemmological characteristics of mask layer, includinghardness, reflectivity (gloss strength) and elemental composition. Research shows that, compared with other traditional coating methods, coating surface gloss,hardness of gem in combination with the sapphire substrate, and the rateincreased, the gem more attractive and durable value. And through the abovethree kinds of test methods, can accurately measure the surface of the coatinglayer information, and the characteristics of these information with similar natural gemstones are different, so it has significance for reliable identification of gems.
-- Exploration of linear material applied in modern jewelry continuous track
Li Sang of Shanghai Jiao Tong University
Since long time, motion to linear signs of objects in space, the life trajectoryindicates the direction and developing with great interest, promotes the research oflinear material development history in jewelry making. Found no matter what shapejewelry can see traces of it in the history of our country, occupies an important position. Therefore, to its inheritance in individual works, the design concept of theinnovation and exploration of material and linear features, the related technology to try and explore, visual language arts building abstract, disorder, appear wrong, toindividuals seeking to uphold the people on the use of linear material in jewelryattention.
Study on Optimization of diamond color high temperature anaerobic activeenvironment
Shi Jian of Shanghai Jiao Tong University
Study on Optimization of diamond color is in recent years many scientists committed to research. In this study, using a high temperature anaerobic environment, can beslightly yellow and brown diamond change color under the pressure of certain and special climate conditions, and change the color does not need any treatment, can still maintain the original brightness. At the same time using spectrophotometer forthe color change to determine. (source: Chinese Gold News)
