Pearls made of fish fiber extract. The Fisheries Research Institute, under the leadership of some Chinese saltwater experts, has attempted to carry out pearl farming operations by extracting fish fiber. However, the development and expansion of sustainable technology has never happened in our country. The development of this industry is possible through the use of advanced pearl control technology technologies. According to Bangladesh statistics, if it is possible to produce artificial pearls, it is possible to earn Tk 1,500 crore per year. In addition, 20 to 30 people may have job opportunities in the industry.
Natural Pearls and Artificial Pearls:
When oysters are born naturally free, they are called natural pearls. And properly produced pearls are called synthetic pearls. There is no difference between natural and synthetic pearls.
Artificial Pearl Uninstall:
Light extraction from the upper skin of fish scales is considered to be the main ingredient in synthetic pearls by chemical process. The brightness of this extract is rich in guanine (2-amino, which contains oxyapurine), the main natural ingredient in fish skin on top. Due to the presence of guanine in the upper skin of fish scales, it has a silver-white color due to the reaction of collagen and calcium phosphate. This bright shiny silver extract is often found in sea whiting, seafood, herring, ribbon fish, and some marine carp. Often these light extracts are found mainly in sardines and ribbon fish.
In developed countries this extract is widely used to make pearls. After removing the scale from the fish scale by a high degree of refinement, small glass beads are needed to make artificial pearls by mixing acrylic chemical ingredients into them. Made of low quality plastic beads. The Guanine Hall is made up of stellar platelets, rich in crystals, and light-emitting pearls, which transmit light from S-rays. Ethyl alcohol is used in a clear, transparent substance to make high-quality guanine. Refined guanine is then mixed with acetone or amyl acetate, or celluloid or nitrocellulose or albumin to make pearls of high quality synthetic pearls. Although albumin is a national essential protein of pearl luster, the chemical component plays a major role in the production of pearl extracts. The main chemical compounds produced from pearl making are water-soluble guanine, alcohol, ether, chloroform, ethyl acetate, acetic acid, and many acids. However, it also dissolves in acids and alkalis.
In 1856, Fran ক ois Jacquin, a French beadmaker, invented the first pearl to be weighed on a fish scale. Today, artificial pearls are produced worldwide for their special use in refining. It is called ‘desence d’orient’ in French because it was first discovered in France.
Pearl extract is widely produced at the level of herring fish extracted by the herring fishery of the Pacific British Columbia herring. One pound of pearl extract is produced in a ton of 100 ton fish herring.
Uninstall collection method:
This shiny silver outlet should be collected by sharpening the strands of marine ribbon fish or belt fish with a sharp knife. This light-emitting silver must be stirred or shaken several times in the water to collect the bright light of the guanine crystal. Then mix a small amount of acetic acid with 0.25 pepsin in a thick liquid lying on the object and leave it at room temperature for 48 hours. It is assimiligated through chemical reaction and the non-vegetarian bananas in the extract extract. Acetic acid is also used for acidification. When metallic acid is reused, guanine is added. Crystals rich in de-propionized guanine are extracted and mixed with ether solution or gagsolin solution. Over time crystals rich in guanine can form a solvent that can decompose. Contaminants mixed with water and any foreign objects float below the water level. A small amount of oil content takes place at the ether level. The ether layer is then carefully separated. Guanine-rich crystals are washed with dry ether 2 to 3 times simultaneously so that fats are regenerated and stored in ether and ethyl acetate. Pearl extraction is found in a scale of at least 0.3% of the weight of a ribbon fish. The best output of pearls is 30 microns long and 3 meters wide and 1.6 in average weight. The pearl extractor is machine-bound with empty glass beads and covered with melted wax to make artificial pearls, but pearls made of bare glass beads can be easily broken. Apple glass or alabaster is used to make high quality pearls.
