The high-Tc glass model can be combined with the repulsive tt'–Hubbard model as microscopic description of the striped domains found in the high-Tc materials. In this picture, the finite Hubbard clusters are the origin of the d-wave pairing. In this paper we show that the glass model can also explain the critical currents usually observed in the high-Tc materials. We use two different approaches to calculate the critical current densities of the high-Tc glass model. Both lead to a strongly anisotropic critical current. Finally we give an explanation of why we nonetheless expect a nearly perfect isotropic critical current in high-Tc superconductors.
