  We investigate properties of strongly interacting matter in a schematic
model, based on the combined degrees of freedom of a non-interacting hadronic
phase and a non-interacting deconfined phase. It is found that in a finite
system both phases contribute to the thermodynamic state due to fluctuations
and that signatures of critical behviour like the divergence of statistical
quantities are damped. The constraint of color-neutrality leads to a
volume-dependent shift of the effective critical temperature, which follows a
scaling law, independent of the baryochemical potential. According to the
model, observable baryon-number susceptibilities at a given $T$ and $\mu_B$
strongly depend on the system size. Finally, we compare hadronization
conditions from the model with hadrochemical fits to experimental collider
data, where a qualitatively similar system size dependence is extracted.
