In this short communication we consider the possibility that stars lessevolved than the polluters are the source of the dilution needed to explain theobserved composition of second-generation globular cluster (GC) stars and theNa-O and Mg-Al anticorrelations. If these stars can lose 0.5-1% of their massduring the relevant epochs, there is enough diluting material to produce theobserved anticorrelations. In this case, the original mass of proto-GCs wasseveral tens times higher than the current mass of GCs. While not strictlyimpossible, this is a stringent hypothesis that needs more support. Should thisscenario be found true, then the link between the primordial (first-generation)population in GC and the field population would be very strong.
