They move faster and faster. Eventually they move fast enough that they break free of their place in the lattice and the ice melts.
First the ice is melted; after this the water is evaporated. By heating intermolecular forces were broken. But the chemical formula of water remain unchanged.
Many salts do not decompose when heated.
Sodium Carbonate
For example stable oxides as aluminium oxide.
Certainly! That's what they're designed for.
the iron ring, the wire mesh over the ring, the beaker or whatever else was being heated. There are special tongs for most types of glassware or porcelain objects that are heated over a Bunsen burner.

Many salts do not decompose when heated.
A Bunsen burner is not made of pyrex, it's metal. Usually a beaker or flask made out of pyrex glass is heated by the flame from the Bunsen burner.

Because it is flammable substances
