OK, I must have missed something or some post Re: yellow ochre and
pickle. When I’ve had to use yellow ochre, I have always placed the
piece in pickle to remove the y.o and flux, etc.
Is there some health or safety reason for not doing so? If so, or if
one prefers not to pickle the piece, ochre and flux can be removed by
boiling the piece in a strong (saturated) solution of baking soda.
Works fine, too.
