The difference between natural crystals and artifical crystals:
The main chemical ingredients of the natural crystal and artificial crystal is silicon
dioxide.Natural crystal is made from naturally occurring high purity silica,it is high hard,good reflecting.However, most of the natural formation of crystals containing impurities and air bubbles, resulting in opacity and can not be laser engraved inside,it is hard to sculpture on the surface of crystal also.And a small number of pure natural crystal can not meet peoples needs ,because of the high price .The main chemical ingredients of the natural crystal and artificial crystal are same. But most of the natural crystal and there are not, or very few ingredients containing lead oxide.
Therefore, to increase the crystals optical permeability, but also to make crystal is more pure and beautiful, to highlight the noble the artificial crystal need to join the lead oxide component.After the initial forming of the crystal still need to go through professional and technical personnel, well-cut polished and artistic process in order to meet the requirements of crystal crafts.To show our respect for customers,we Rongcan Crystal Arts & Crafts have particularly stringent requirements.in above several steps.
The similarities and differences between artificial and general glass
Have in common is the same chemical composition, are silica,followed the physical performance is very similar to the external, are colorless and transparent.The difference is the artificial crystal has added oxides to change the color and purity .Because of this, a careful identification will find that it is greatly difference in the light transmission and refraction of light between artificial crystal and general glass.Crystal light relative to the average refractive index of glass is closer to the refractive index of air,so it is more transparent and pure crystal, more suitable for doing a beautiful arts and crafts.Another ,the molding process is different,crystal is noble and beautiful,She is beautiful, but fragile.Therefore,it is not like the glass can be full controled by machine in the process of forming.In order to respect her noble artistic, most of the crystals in the forming process is through the professional and technical workers and fine fragmentation and polished.Because of this, the value of crystal is higher than ordinary glass.
The method of the manufacturing molding of crystal handicraft :
The original material of artificial crystal is crystal powder. The crystal powder is heated to over 1400 degrees, then add a variety of chemical substances even after stirring can cool the crystal shape presents a variety of colors. If it is white crystal only with adding a certain amount of lead oxide will appear to be very translucent. The quality of crystal will improve with increasing the lead oxide.After crystal forming, in order to make crystal hardness Cutting the need for arts and crafts.,it need to go through annealing.It will become to crystal materials after above steps.It needs to go through three major steps:the process of cutting, grinding and polishing before from crystal material to crystal craft. Because these three steps relates to the overall product quality, it is the most highlighted part of the work of several parts which we insist. We hired a group of highly skilled fine, careful work of technical personnel to undertake this part of the work. This is a method of preliminary molding. We according to customers needs for crystal paste, sand blasting, laser and color printing and other processing after the initial crystal finished.we will introduce each of these methods and the role of processes. |
