Ceramic Clay Fire Assay Crucible For Lab Gold Melting and Precious Metal Analysis

Metals recovered in fire assaying crucible are the metals that emerge from the fusion of the material in a assay furnace, for gold, usually at temperatures of about 2,000 Degrees F. The Fire Assay Method is centuries old, but it is still one of the most reliable methods for performing assays (to determine the metal content of a ore) of ores that contain precious (noble) metals - Gold, Silver and Platinum.

PRODUCT INTRODUCTION

Accuracy in sampling, preparation, assaying, handling, weighing is extremely important in fire assaying,

since errors will influence the 0.0001 g final gold bead in sometimes astronomical proportions, if done improperly, using un-scientific methods, and little attention paid to the assay process.

It is important to choose a high quality fire assay clay crucible

Customised size is acceptable.Top quality and quick service are our goal.

INTRODUCTION

Fire Assay Crucibles have a higher than normal resistency to cracking under fire assay conditions. Our crucibles are used in laboratories throughout international marketplace. We have a variety of shapes and sizes available to cater to specifications required.

Our crucibles give longer life, faster melting, constant melting speed and exceptional resistance to violent changes of temperature.

Quality China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold Manufacturer | XTL

6A 7A 8A China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold compared with similar products on the market, it has incomparable outstanding advantages in terms of performance, quality, appearance, etc., and enjoys a good reputation in the market. Xngtailong summarizes the defects of past products and continuously improves them. The specifications of 6A 7A 8A China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold can be customized according to your needs.Cupel is a porous refractory for absorbing lead oxide when ash blows the lead buckle. The main component of magnesia is magnesium oxide, which is a very good refractory and can resist the erosion of alkaline flux. Lead oxide is a very strong alkaline flux. At high temperatures, the affinity between lead oxide and silica is very strong, which can invade the silicate in the cupel. There is more silicate in the ash cupel and cement cupel. After blowing with this kind of cupel, there will be pits on the surface of the cupel, and precious metals will be lost as a result. Using magnesia cupel, no such phenomenon after ash blowing, the surface is very smooth.
