ForglassBox – 21st century technological support for glass producers

Forglass, the glass melting technology supplier, introduces ForglassBox – the first application of its kind,
performing technological calculations on a smartphone. It enables instant calculation of a batch
composition, based on selected raw materials of defined chemical composition, from which flint
(colourless), amber, green and olive glasses can be melted with a desired chemical composition and
ForglassBox allows the user to select specific raw materials and assumptions (limits) for batch and glass
according to its colour requirements, and it calculates the technological and physicochemical properties
of these glasses, including: temperatures at which the glass reaches desired viscosity, liquidus
temperature, cooling time, WRI, RMS, RGT, linear thermal expansion coefficient, density, specific
electrical conductivity, heat capacity and effective thermal conductivity. The ForglassBox application has
built-in “intelligence”, thanks to which it also corrects the chemical composition of the glass selected for
calculations, if the selected raw materials make it impossible to obtain the assumed concentrations.
