The characteristics of the blue glaze base in Yuan Dynasty
In the Yuan Dynasty, the imported Cobalt material used to fire the blue glazed porcelain was very precious, and the hair color was still unstable. The blue glazed porcelain of the Yuan Dynasty was mainly "white flowers on the blue ground", and it was more common to see clouds and dragons, and it was almost impossible to see a plain glaze without patterns. The thickness of the matrix is moderate, the matrix is dense, hard, and the degree of porcelainization is high. In addition, ancient porcelain bodies may contain purple gold soil (purple gold sand). Due to the use of purple gold soil, a small amount of brown bubbles may appear under the fired porcelain, like the color of bubbles in soybean oil. This bubble can be used as a basis for identification. At the same time, Yuan Dynasty porcelain was limited by the processing technology at that time. There were many flat feet, many papillions and jumping knife grooves, and the knife cutting was irregular.

Is the yellowing of teeth mainly a reaction to the color of the glaze?
The yellowing of teeth was not entirely a reflection of the color of the glaze. Teeth were made up of the dental pulp complex, which was made up of the inner layer of the tooth's glaze. The tooth's glaze had a certain degree of penetrability. A pale yellow tooth indicated that the tooth's glaze had a high degree of weathering. The color of the dentinus was exposed, making the tooth look pale yellow. This was a normal phenomenon. However, there were many other reasons for the yellowing of teeth. In terms of lifestyle, long-term consumption of dark-colored food or drinks (such as tea, coffee, cola, betel nut, etc.), long-term consumption of soda, smoking, or using cigars will cause teeth to turn yellow. Under the long-term stimulation of the soda, the originally strong tooth glaze was corroded and thinned, exposing the dentinum, and the teeth turned yellow. From a medical perspective, the use of tet can cause dental problems (tet teeth), and the intake of too much fluride can lead to fluoridation, which can also cause teeth to turn yellow (dental flurosis). In addition, if the teeth are not well nourished or sick during the development process, it will affect the teeth's biochemistry, making the teeth yellow and brittle; if you don't pay attention to oral hygiene, the accumulation of food residue, soft dirt, tartar, smoke stains, tea stains, etc. on the surface of the teeth will also cause the teeth to turn yellow. Since there was no actual picture for analysis, it could only explain the cause of yellowing teeth from the general situation. The actual picture analysis needed to take into account the overall appearance of the teeth, color distribution, yellow spot position and other factors to determine the cause of yellowing teeth. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Titanium preparation process from ilmenite
The process of preparing titanium from ilmenite was as follows: 1. First, ilmenite was dug out from the mountains and smelted at a high temperature of 1800 degrees to separate the iron and make it into high-titanium slag. 2. After the high-titanium slag was chlorided, it was made into titanium dioxide. 3. Under the protection of an inertia gas, titanium dioxide was reduced with metallic titanium at a high temperature of 900 degrees to obtain titanium sponge. 4. The titanium sponge was pulled to Baoji and placed into a vacuum smelting furnace for dozens of hours to be smelted into titanium ingots. 5. The titanium ingot was used for forging and made into a rod. 6. The rod embryo was rolled several times, peeled, straightened, polished, and other processes to make a 10mm round rod. 7. The round rod was then processed into finished products such as screws on the lathes (This step was an extension of the production of titanium products, not the core process of preparing titanium). In addition, the industry can also use concentrated sulfuric acid to treat the ground ilmenite (concentrate), causing a chemical reaction: FeTiO3 + 3H2SO4 ==Ti(SO4)2+ FeSO4 + 3H2O, FeTiO3 + 2H2SO4 == TiOSO4 + FeSO4 + 2H2O, FeO+ H2SO4 == FeSO4 +H2O, Fe2O3 + 3H2SO4 == Fe2 (SO4)3+ 3H2O, then to remove the impurity Fe2 (SO4)3, iron filings were added to reduce Fe3 + to Fe2 +, and then the solution was cooled to below 273K. FeSO4·7H2O (green meteorite) was crystallized as a by-product, Ti(SO4)2 and TiOSO4 were decomposed to form white metatitanic acid, and then titanium was obtained through a series of reactions. The other method is to pre-reduce the iron ore containing titanium in the pre-heating section of the electric heating kiln, and then directly electrify the iron ore or the solid material obtained during the heating process through the power supply pole in the heating section of the electric heating kiln, and then use the resistance heating material in the material pile in the heating section to heat up the iron ore to reduce the iron in the iron ore in the oxided state into the iron in the metallic state, and then separate the oxided titanium and the iron in the metallic state from the iron ore in the smelting process. Then, titanium was produced. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
The reaction process is an acidic electropathic substitution reaction.
In the process of an electropathic substitution reaction, an electrophile (such as a positive ion, Lewis acid, etc.) would attack an organic molecules rich in electrons (such as the aromatic ring), forming a positively charged intermediate (such as a carbon ion on the aromatic ring), and then leaving a photon to complete the substitution reaction. For example, in the Frieder-Crafts alkylations, under the catalyst of a strong Lewis acid (such as dehydrated iron), the halo compound produces a carbon positive ion. This carbon positive ion acts as an electrophile to attack the aromatic ring and replace the hydrogen on the ring. Finally, it produces an alkylaromatics and hydrogen dioxide. In the C-alkylations, which was an acidic electropathic substitution reaction, the hydrogen on the carbon atom of the organic compound was replaced by a radical, and the alkylations (such as alkene, halane, alcohol, aldo, and others) participated in the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of the format preparation reagent and the keto
Grignard reagents were generally made by reacting an alkyi radical with metallic aluminum (usually fine wire or powder to increase the surface area) in absolute ether or in the presence of lithium ether (CHF). The preparation method was to slowly add the ether solution of a class of aromatic alcohol (commonly used class of aromatic alcohol or class of aromatic alcohol) into the mixture of the ether soaked in the ether. The speed of adding the ether should be able to maintain the ether boiling slightly until the mixture of the ether and the ether disappeared, and then the Grignard reagent was obtained. The reaction is an exhalation of heat. If the reaction is slow to start, a small particle of iodine-can be added to start it. Once the reaction begins, after the ether boils, the ether vapor is enough to eliminate the air in the system, but water is not allowed. Vinegar and the chorine bound to the ene carbon could not react with lithium in ether. If the ether was replaced by potassium ether, the reagent of lithium could be prepared. Grignard reagents could react with ketones. Under suitable reaction conditions, such as the Grignard reagent prepared by the researchers of Hokkaido University in Japan using ball mill technology, in the presence of a small amount of potassium furane (TH F) or cyclopentyl methylether (CPME), the prepared Grignard reagent reacted with an electrophile reagent such as a keto to construct a C-C bond to obtain the corresponding alcohol product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Oxidative decomposition reaction process
Oxidative decomposition was a decomposition reaction. It was a reaction involving oxygen and required the participation of a specific enzymolysis ase. However, it did not consume water molecules and released hydrogen and energy. During this process, the substance would react with oxygen to form an oxide-like substance, releasing gas, heat, or light energy. This reaction was a kind of oxido-reduction reaction, in which oxygen was used as an oxidiser to accept electrons, and the reacted substance was used as a reducing agent to lose electrons. This reaction usually required high temperature or the presence of a catalyst to provide enough energy to overcome the activation energy of the reaction. For example, in cell breathing, glucose reacted with oxygen in the cell to produce carbon dioxide, water, and energy; when organic matter was burned, it reacted with oxygen to produce carbon dioxide, water, and heat energy, which were all manifestations of the decomposition reaction process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
