This study was an aim to apply lacing technique to produce yarn accessories for value added and developing the new products. It was a survey research by questionnaires tool. The study was divided into 2 steps. The first was collected the basis data for product analyzed and appropriate design to produce the prototype products. Thai traditional design was chosen to master design prototype as kanok naree kacha and krabi traceries. All of these traceries are gentle and shown as the Thai design. Kanok is a thai traditional style that it was chosen for a represent design and combine together with product design and decoration trend on 2013-2014 in Formal & Sugary style. The prototype products 7 collections: necklace earring and brooch. The prototype products were accepted from the sample group which they were very good in the factors of the beautiful technique the utilization and the quality of products. The prototype had price in range 801 – 1 300 Bath. The prototypes were adequate detail. From these results the prototypes were response with customer and make an alternative choice to increase the household income.

This Research is to Study the Development of 6k White Gold Low Alloys Metal for Jewelry Production The Optimum Conditions for Casting Jewelry and Jewelry were Investigated. The Results of the Experiments Show that the Chemical Composition of the 8k White Gold Low Alloys is Slightly Different when Compared with XRF (X-ray Fluorescence Spectrometers) Pre-and Post-Melting Quantities The Heat of the Test Specimen was found to be 33.33%Au+50.67%Ag+10%Cu+5%Zn+1%Sn33.33%Au+50.67% Ag+8% Cu+7%Zn+1%Sn and 33.33%Au+50.67%Ag+8%Cu+8%Zn+0%Sn It is Found that the Heat from the Beginning to the Level of Change before the Liquid is used the Average Temperature of 458.9 – 326.3 Degrees Celsius Respectively 33.33%Au+50.67%Ag+8%Cu+7%Zn+1%Sn It is the Formula that Gives the Lowest Value of Liquid State Change from 326.3 Degrees Celsius to the Best Value of this Experiment. Suitable for use in the Manufacture of Jewelry due to its Melting Ability for Molding. Melting for Molding and Formed by Hand. The Amount of Zinc(Zn) may be an Important Factor in the Variation which is Directly Proportional to the Maximum Increase in the Final order of 7 Percent

The purposes of the research were to create and efficiency validation of computer assisted for the Computer for Jewelry Design based standard 90/90 and analyse the leaning achievement ofthe student after by using computer assisted instruction. The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted Computer for Jewelry Design. After that let students do the unit test again at the class and calculate to fmd out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study . The research result revealed that the efficiency ofthe computer assisted Instruction was efficient in standard 90/90 Moreover after learning achievement At significant level of 0.05.
