Yes they are the norm, but the HFC acid is very dangerous and you should make sure you used the correct safety gear/precautions when using said acid/s.

If there is quartz with the gold, and you think the quartz could become whiter, then wombat told me to soak
It in domestos for a bit, sorry  can't remember how long for  scratch
Also I have seen some of Wombats gold with quartz, the quartz was whiter, but I don't think it works
For all quartz.
