There are quite easy and simple ways to distinguish crystal from glass. Distinctions can be found also in external signs, it is worth looking at products only more attentively. Even the ordinary person who does not have certain knowledge will cope with this task.
Instruction
1. So, there are several types of check. One of them is the tactile method. Take crystal and glass and compare their temperature. Crystal in this case with other things being equal will be colder in comparison with glass. It is possible to use the same way when heating these two objects. Begin to heat gradually them, and you will notice that crystal heats up more slowly than glass.
2. On the surface of crystal it is very seldom possible to see any scratches, it is very difficult to damage crystal. What it is impossible to tell about glass. However do not think that it is difficult to break it, crystal not such strong material, such as diamond.
3. If to speak about artificial crystal, then give it to experts, let they will make to you examination on identifications of percentage of lead. Crystal in this case should not have more than 10% of oxide of lead, and here glass, on the contrary, has to be present at its contents no more than 4% of this substance.
4. Look narrowly more attentively in structure of glass and crystal. Glass will be obligatory to have slightly noticeable gas bubbles. Look at crystal, these bubbles should not be here.
5. Look through glass at light. You can see, so-called twisted, these are lines of a current of final substance from which glass turns out subsequently. If you look at light through the real crystal, then will not see similar lines.
6. Observe how other objects when you look at them through crystal or glass look. Glass, uniform on thickness, is capable to increase objects only slightly. Crystal in that case has very noticeable bifurcation. All ways given above to distinguish crystal from glass are not exact, it is the best of all to address the experts working in this area.
