Effetre Light Gray (EFF248) is an elephantine opaque colour. It is somewhat reactive with Ivory, fairly inert with other colours, and makes an interesting base colour for silver and silver glass.
When you reduce it, Light Grey 'browns up' a little.
Silver on top of Light Grey turns yellowish and pinkish. When the silver is reduced and encased, it loses this interesting colour.
Reducing silver glass spreads and develops a nice sheen on top of Light Gray. I got a decent starting strike from my TerraNova2 on top of this colour, and like the pale halos that I can see around the TerraNova2 fritty bits.
Light Gray separates a little on top of Tuxedo.
Ivory and Light Gray develop a reciprocal dark line reaction. In the case where the Ivory is on top, the result is a dark line that almost looks like a shadow. When the Light Gray is on top, the reaction is crackly and intermittent, giving the stringer lines and dots a translucent, jagged appearance.
