JSJ spends a exceptional amount of its money on research and development. Our glass scientists and engineers cover all relevant scientific and technical disciplines. For our customers benefits together with glass producers, research institutes JSJ is permanently developing technical improvements based on our own ideas.

Thanks to our laboratory we are able to conduct

• all kind of melting investigations from laboratory up to production scale
• measurement of dynamic viscosity and specific electrical resistivity
• experiments on corrosion behaviour of all refractory and electrode materials in various glass melts
• mathematical modelling of melting furnaces and forehearth including fields of temperature, flow, residence time and electric power distribution
• physical modelling of glass flow
