CiM Flax is a pale, transparent, golden yellow champagne colour.
Here are three self-coloured beads in Flax.
You can see that the Flax has reacted with the silver to make a beautiful, rich rootbeer / topaz colour. The monster air bubble stayed silver (so the reaction only happens where the flax touches the silver, and at the top, right, of the bead, it where I accidentally hit the silver with the flame before encasing and melted the silver in. Still looks pretty cool.
Flax - super-reactive with silver.
