Na2SO4 ---> Na2S

I'm not sure how to get rid of the O4... I think I'm supposed to heat it to a really high temperature but I am not sure... Would anyone have the clues to remove the O4? I have searched online but all I get is ways to get Na2S in more complicated ways... I have already tried heating it for a few minutes at a high temperature and nothing happened... Should I let it get hotter?

It is not that easy, sulfates are quite stable.

Well how would you go about doing it then? Do you know how? It has to be that easy because what I'm going to be doing is decomposing the sodium sulfate into sodium sulfite... I will attept one more time but I will do it at a hotter tempature and for a longer peroid of time... I think what I'm doing is almost burning the stuff... That's to goal...

I read that I need to add carbon in the form of coal but this makes absolutely no sence to me because all I'm trying to do is get rid of the O4...

Edit:

Actually I think your right... It might be harder than just baking the stuff but I will still go ahaid with the experiment and tell you guys if it worked... It should turn yellow or red...
