Fascinating reading your posts regarding the change in phenolic beads.

Just wanted to quiz you further if that is okay.

You say the non-phenol beads give off a bad odour in under five minutes. How long does the colour change take in genuine beads?

Also when you hold a successful colour change bead to the light what effect is shown? Is it that beautiful marble cloudy effect that you see so often in these so called "cherry amber beads"?

Hope you don't mind me asking.
