The White Sun - Cabala mineralis
The “white sun” is a synonym for the white stone.
You can see the material being heated in the flask, with the peacock’s tail appearing. Here’s the description, from Adam McLean’s alchemy website:
Volatilisation through liquid.
Here our white sun, without any imposition of a hand, nor opening of the flask a second time, is melted, the heat having been continued, with many coloured vapours resembling the tail of a peacock, then our white sun is being volatilised through a liquid.
Seems like Jaime and Brienne both achieved the White Stone--but got stuck there.
