Atomic scale molecular dynamics simulation is used to investigate how alkali concentrations in glass adjacent to interfaces with crystal surfaces, might differ from those within the interior of a bulk glass. A sodium, lithium alkali-borosilicate glass and its interfaces with the (1 0 0) and (1 1 0) surfaces of MgO, CaO, and SrO are considered. These six interfaces were formed by melt-quenching the glass in the presence of the crystal surface, providing glass alkali ions with the opportunity to either migrate towards or away from the crystal surface. The resulting alkali contents adjacent to the interface are found to differ depending on crystal composition and surface orientation.
