That's not quite what I suggested. I do know that chrome will create crystals as in "Aventurine" in the right concentrations at the right temperatures but it's not a glass I have much experience with. I do think anytime you have a color hanging around 16-1700F, it is in the happy range for crystals forming. Color rods certainly have to go through that range. I'd still ask John.
Where are we going and why am I in this basket?
