Figure 2

Pores in actual disordered porous materials such as Bioglass are much more complex, yet they tend to have analogous well-type morphologies. The pore is completely filled with solution. Flat pore walls prevent the nucleating crystal from trying to conform to any curved pore surface and becoming strained40. Crystal building blocks on the surface (i.e. in contact with the bulk solution) are highlighted in light blue.
