You will get BaO and SO3:
BaSO4 --> BaO + SO3
If you continue to heat BaO will decompose into elemental Ba
2BaO --> 2Ba + O2
Elemetal Ba will then burn in the flame to give the characteristic flame test.

BaSO4------->BaO+SO3 and if u continue BaO------>Ba+O2and it make the colour of the flame green(the light green like the pistachio)

Most likely, the following reaction will take place:
2BaSO4 --> 2BaO + 2SO2 + O2
