Why does sodium carbonate not decompose when heated using a Bunsen burner?
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.
Which elements may be excited using a Bunsen burner flame?

If you want to get realy fancy use a heated cermic surface. This have like a magnetic stirrer with it as well and you set the temperature.
What are the advantages disadvantages of thermador cooktops?
When using a thermador cooktop, only the pot or pan used is being heated and not the burner. When using electricity or gas, the burner gets hot as well as the pot or pan being used. Thus, thermador cooktops are more energy efficient by cooking faster and cooling down faster.
