Hi M'lou, If you do mix some of this alloy up you'll want to be sure your 14K crucible is picked clean and free of de-ox alloys. I steer clear of deox alloys in my studio but I know this alloy can be contaminated by them and not work.
This alloy make tough springy bezels (you may want to use regualr rolling alloys for the bezel part) and only fair castings but I use it exclusively for the color. The great thing about engraving is it hides imperfections in castings. Also I assume that only diamonds can stand up in the chemical bath but I have also done rubies, beware with colored stones. This patina is a bit like ceramic glazes and can be elusive at times.
One new tip is use all fresh ingredients and add some ammonia lemon scent ok. Top off with ammonia as the solution boils down and use a stainless bowl. Also set the ring on white gold trivets to keep it off the bottom.
