The quenched spectrum of glueballs with positive charge parity is calculatedfrom two-body bound state equations. As input, a self-contained solution forthe primitively divergent correlation functions from Dyson-Schwinger equationsis used. It only has one parameter to be set which is the physical scale. Animportant feature of this setup is the consistent construction of the boundstate kernels along the same lines as the equations from which the input wasobtained. Keeping only the one-particle exchanges, already good agreement withlattice results is obtained. For the tensor glueball, we present first resultsincluding two-loop contributions, elevating its calculation to the same levelof truncation as for the spin zero glueballs for which such calculations havebeen done previously.
