solid crystal in the glass?

1.	solid crystal in the glass?
Answer» Amorphous solids are isotropic - meaning while measuring a particular property of the material, you'll get the same result no matter from which side or length of the material you take your measurements from. For example the electrical resistance of a glass piece would be the same through out its body - inside the bulk, surface, through the length or through the breadth. However, since Crystalline solids have a long range order, their arrangement of particles in different directions would be different and hence they would behave as an-isotropic materials. Crystalline solids are more rigid. In fact, if you come across a very old glass you'll observe that it is bulkier downwards. This is because glass particles are very slowly flowing downwards under the effect of gravity. This would not happen in a crystal.
