What is the probability of getting this on fail alchemy.....does it just a junk after you did any alchemy or just when you make a fail one?

Been attempting to craft this with no luck.
Recipe suggests 10 items.
"traces of flame": powder of flame?
"coal processed by children": processed coal?
"broken black stones": black stone powder?
"an indomitable will": ???
"shining particles just like their tiny selves": shining or fairy powder?

I have attempted using oil of fortitude, elixir of will (blue and green), and origin of life for the "indomitable will" with no luck.

Flame, coal, blackstone, and shining powder (no indomitable will part) also did not work. I tested this one with black stone powder and black gem fragments. Also, shining and fairy powder.

Im guessing once we figure out this recipe we will be able to craft the inextinguishable stone at a 6% rate with charred stones being the common result. Any assistance is appreciated.
