  We apply a recently developed optimization scheme to obtain effective
potentials for alkali and alkaline-earth aluminosilicate glasses that contains
lithium, sodium, potassium, or calcium as modifiers. As input data for the
optimization, we used the radial distribution functions of the liquid at high
temperature generated by means of ab initio molecular dynamics simulations and
density and elastic modulus of glass at room temperature from experiments. The
new interaction potentials are able to reproduce reliably the structure and
various mechanical and vibrational properties over a wide range of compositions
for binary silicates. We have tested these potentials for various ternary
systems and find that they are transferable and can be mixed, thus allowing to
reproduce and predict the structure and properties of multi-component glasses.
