For example stable oxides as aluminium oxide.
Certainly! That's what they're designed for.
Carbonates often decompose when heated, forming gases and a residue. Hydrogen carbonates may decompose as well, but different compounds have different ease of decomposition. Aluminum chloride sublimes (changes directly into a gas from the solid state) when heated.

Sodium carbonate does decompose when heated, it undergoes thermal decomposition to form sodium oxide (Na2O), carbon dioxide (CO2), and water (H2O). However, the decomposition of sodium carbonate is not easily noticeable when using a Bunsen burner as the high temperature and rapid combustion of the gas can mask the decomposition reaction.
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.
