The indirect evidence for gluonic objects in gluon jets is recalled, more accurate tests at the LHC are possible. Estimates of gluonic and quarkonic components of scalar mesons are presented, which could be improved by further studies, in particular of B and Bs decays. The results are consistent with the scalar glueball mixing into f0(500) and f0(1500). The study of symmetry relations for 2-body decay rates of charmonium χc is suggested as crucial test in the identification of q q multiplets and glueballs. Further related results are discussed in the recent review \citeOchs:2013gi.
