pearl bleachin
Blowing pearls was an optimized treatment method, and the commonly used bleacher was hydrogen peroxide-based. The hydrogen Peroxide-Blowing Method soaked the pearl in a solution of 2%-4% oxygen dioxide at a temperature of 20 - 30°C and a pH-value of 7 - 8. At the same time, it was exposed to sunlight or ultra-violet rays. After about 20 days or more of rinsing, the pearl would turn gray-white or silver-white, and when the effect was good, it could turn pure white. In addition, the rinsing method could also be used, but improper use could cause the pearl to become fragile and brittle, or leave a chalky powder surface, so this method was generally not used. Blowing the pearls could not completely turn the color groups white, so fluorescent brightening agents were often used to increase the whiteness and brightness of the pearls. The fluorescent brightening agent was a kind of fluorescent dye. It would have a fluorescent reaction under the purple light. It would absorb the invisible violet light in the sunlight and transform it into a visible purple-blue light, turning the pearl into white light.

What is the method of bleachin g wool?
Wool could be bleached using two methods, namely, oxygen and reduction. Oxidative bleachers such as hydrogen dioxide and potassium permanganate could be used. The commonly used one was hydrogen dioxide. The hydrogen dioxide could break down new oxygen and destroy the organic coloring in the wool. It had the characteristics of good whiteness, long-lasting, and not easy to yellow, but it would cause certain damage to the wool. There were two methods of bleaching-dipping and steaming. The dipping and rinsing method was to soak the wool in a solution of hydrogen dioxide at a temperature of 50 ° C for 10 to 15 hours. The concentration of the rinsing solution was determined by the content of the dye in the fiber. The acid can be neutralized by the addition of a solution of either Na-SiO2-SiO3 or NH3-NH2. In addition, it could also be restored and bleached with insurance powder. The requirements were not high, and it would not damage the strength of the wool fiber. However, insurance powder may be difficult to buy in an individual or family.

Why are single spiritual roots the most powerful in cultivation novels, while double spiritual roots, three spiritual roots, and four or five spiritual roots are not good?
In cultivation novels, a single spiritual root was considered the most powerful because a single spiritual root often had higher cultivation talent and was easier to comprehend the basic principles and techniques of cultivation. Under normal circumstances, people with a single spiritual root were more likely to break through bottlenecks and quickly improve their cultivation level.
In addition, in some immortal cultivation novels, people with single spiritual roots were often regarded as spiritual roots with special abilities, such as being able to sense the existence of other spiritual roots or having some special abilities, which made it easier for them to communicate and cooperate with other immortal cultivators to obtain more cultivation resources and opportunities.
However, people with dual, triple, and quadruple spiritual roots also had some advantages. For example, people with double spiritual roots could often help each other to improve the efficiency of cultivation, while people with three or four spiritual roots had unique advantages in certain aspects, such as being able to use different spiritual powers for cultivation or having special talents and abilities.
Therefore, although a single spiritual root was considered the most powerful, not everyone was suitable. Different spiritual roots had different advantages and characteristics. Choosing the right spiritual root was crucial to the success of cultivation.

A single attribute spiritual root was called a " single spiritual root ", and the cultivation speed was faster. A spiritual root with two attributes was called a " double spiritual root ", and the cultivation speed was slightly slower than a single spiritual root. A spiritual root with three attributes was called a " triple spiritual root ", and so on. A spirit root with five attributes at the same time was called a " pseudo spirit root ". This kind of spirit root was almost impossible to cultivate.
