  We use a lattice of nonlocal confining solitons to describe nuclear matter in
the Wigner-Seitz approximation. The average density is varied by changing the
size of the Wigner-Seitz cell. At sufficiently large density quark energy bands
develop. The intersection of the filled valence band with the next empty band
at a few times standard nuclear density signals a transition from a color
insulator to a color conductor and is identified with the critical density for
quark deconfinement.
