Description
Technical Field
The utility model relates to a jewelry evaluation instrument field especially relates to a jadeite egg face transparency effect grading instrument.
Background
Zhao Ming Kai in the article "measurement and grading of jade transparency" proposed the quantitative method of jade transparency, which is also the evaluation method used in the national standard of jade at present. Firstly, measuring the light transmittance T of a sample with the thickness of n by using a photometer method (a measuring instrument consists of a light source, a measuring box, a photocell and a galvanometer), and then utilizing a formula
(n is the thickness; T is the light transmittance in mm of an object of n thickness-1) The light transmittance, i.e., the unit transmittance t, of an object having a thickness of 1mm was calculated.
This method is relatively accurate and the measurement results conform to the mineralogical definition of transparency of the material. However, the method is low in popularity at present because the unit transparency evaluated by the method is meaningless to the overall effect of the finished jadeite product and has no direct relation with the value of the finished jadeite product. In the jewelry market, the finished jadeite product has high value and is not destructible, so the evaluation criterion of the finished jadeite product in the market is the 'water head' of the jadeite, namely the integral transparency effect of the finished jadeite product. The transparency effect is a transparency visual effect formed by the combined action of the transparency of the material, the cut of the finished product, the color and the thickness as auxiliary components.
In addition, the emergent light hole of the method is 2mm, the general size of the finished jadeite is more than 5mm, and the jadeite finished product is not uniform enough, so the result of the method cannot reflect the whole transparency effect of the jadeite, and the used components are complex and only suitable for being used and measured in a laboratory, so the method is not popularized.
