Many energy star light strings use LED technology, which is energy-efficient when producing a single color and consumes 90% less energy than incandescent lamps. Save more: 10 times longer duration and less energy consumption. Use the new LED technology. Facts and Statistics: if all decorative string of lights sold in the United States are Energy Star certified or LED string/LED string, we will prevent annual greenhouse gas emissions of £ 0. 63 Billion, choose Energy Star light fixtures/LED lighting.
Until the Loke Ching Fatt of Seremban in Malaysia created the original version for the rest of his life (yee sang)Back in 1940, this is still popular in Malaysia today. Then, in 1964, four Singaporean chefs created a new, more colorful version for the island --state. So the chefs, who are respected in Singapore, are called \"four-day chefs\": Liu yabei, Tan Ruiqi, Hooi corner and single beam.

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.
Selected quality quartz as materials, combined with advanced ceramic processing workmanship, mainly used for melting platinum, gold, silver, copper and another high temperature alloy, high purity, anti-corrosion, anti strong acid and strong alkali, good hardness, high thermal shock resistance. The main component is SiO2 ≥80%, Al2O3 (≤17%) and other is 3%( K2O, Na2O, Fe2O3), There is no crack after 10 times sudden heat and sudden cold at 1100℃⇌ 20℃, and no crack after 10 times using oxygen cutting gun to spray 1700-1800 flame on the crucible.

The fire assay method is a classic analysis method that applies the principles and techniques of metallurgy to analytical chemistry, and is one of the oldest methods in analytical chemistry.
The fire assay method is to quantitatively determine the content of precious metals by adding flux to smelt ores and metallurgical products.
