I'm digging for gold.
Specifically - I'm looking for a metallic gold look - because "I am trying to replicate an effect that I got on a bead once but I don't remember what I used."
Like that's never happened to you.
Not sure this was it, but it is interesting and all part of the learning curve.
Hyperion is a light amber that strikes to a deep amber and reduces to an effect from light lustre to mirror.
Held up to the light - it is transparent.
This particular piece, I had a slightly reducing flame and the inital melt went that sludgey grey-brown that we all know and hate. I turned up the oxygen and covered the reduction in fresh glass - but the end result is that the opacity makes for a more reflective piece.
colours that you can see in the photo on Double Helix's site, where you can see a bit of the encasing. I think I must have over reduced it before encasing - according to their working notes. Which was why I was unhappy and covered it up.
As with the Triton I mentioned the other day - best effects come from waiting until all the glow is out of the glass before reducing.
