Aloxidilith Glass

A highly durable version of circuit glass can be made from aloxidilith (alumina-dilith composite), magically heated in a process which progressively layers the material onto a sphere. These are then ground down to the appropriate shape before etching and tempering. The dust produced by grinding pieces to their final shape can be used to make more glass, although the impurities introduced have a negative effect on durability, clarity, and conductivity. It is often mixed in virgin material for cost saving, although material past the third production cycle is generally considered to be lost. Mithril tooling can be used to reduce the amount of impurities introduced, although the energy costs of doing so are prohibitive and result in a net loss (even considering the vast amount of ignium mined within Epacs).
Using precise fire magic, aloxidilith can be fused to ordinary circuit glass without issue. Temporarily interfacing the material with ordinary circuit glass requires both materials to feed directly into a 'connector' substance. Ordinarily, internal projection ends at exactly the edge of the material, creating no contact for transfer of information/energy. Thin platings of noble metals such as gold and mercury can act as efficient connector materials for larger amounts of energy, but will lose any encoded nuance within a beam beyond its frequency (unless they utilize individual 'ports' corresponding to beam sections instead of a single connective surface).
Aloxidilith physically behaves vaguely like mithril- a slight amount of give from which it will perfectly spring back, past which it shatters completely like tempered glass. Its most common use outside of stationary machinery is in weapons and armor, generally suspended within some sort of impact-dampening frame.
Before the Epacsi enchanting boom, aloxidilith glass was only producible in very small quantities, and generally used as a scratch-resistant coating instead of bulk material.
