A question I have been dreading - right concentration
!

As I mentioned.. I am using a commercial grade, and by
that I think the retailer meant it has as much FeCl3
as everything else...

Is that a wrong thought ?

But I still mix about a table spoon in 250ml of hot
water.

Also.. does the depth of the etchant matter ?
