Schwinger-type mass formulas are used to analyze glueball-meson mixing for
isoscalar tensor mesons. In one solution, the f(J)(2220) is the physical gl
ueball, and in the other the glueball is distributed over various states, w
ith f(2)( 1810) having the largest glueball component. Neither the f(2)(156
5) nor the f(J)(1710) are among the physical states without assuming signif
icant coupling to decay channels. The decay f(2)(1525)-->pi pi is consisten
t with experiment, and f(J)(2220) is neither narrow nor decays flavor democ
ratically.
