Iaso is formula AX598. No changes whatsoever were made from the test batch to the production run. No other colors were run in the pot between the test pot and the production run. All materials and composition are identical. Frankly, it's not the type of colors that would change from batch to batch, chemically, it is very stable and consistent. Every pot was tested, and performs the same as the initial batch. Our beads displayed on the website were made from mid-production glass.
It does require particular flame settings, and bead heat and reduction duration are more critical than with, say, triton. I have resisted trying to give specific timings (eg, cool 20 seconds, pass through specific flame "x" number of times, cooling "x" seconds between passes) because it is going to vary from person to person.
But I'll do it anyway:
1) Shape bead
2) Allow bead to cool for 20 seconds.
3) Adjust flame so candles are stretched 2mm from neutral.
4) Pass bead through flame, candles should touch bead and deflect yellow flame around the edges. 1.5 seconds duration for each pass.
5) Allow bead to cool 5 seconds between passes.
6) Repeat pass-through and cooling cycle 5-15 times.
7) Anneal. Turn your kiln down, it's hotter than neccesary anyway.

Here's a short video of the process:-----> Iaso <-----

The reduction proceed is pretty much like Iris, with a slightly different flame setting, and passes closer to the torch face.
