Whiteout replacement - antiflux


#1

I have noticed the chatter of the good and evils of Whiteout as an
antiflux. I understand why you would pefer it to the yellow ocher
liquid, which runs and boils everywhere that you don’t want it.

I recently tried something new. Any of you have the brown or yellow
pencils for marking flasks and investment when casting? These I
believe are ocher in a grease base. I simply coat the piece with my
boric acid/alcohol mix and let it dry, then warm the piece and apply
the pencil where needed. It doesn’t go everywhere when used like the
liquid, and as far as I know doesn’t have bad fumes. Perhaps someone
with more resources/time could check on what the binder is, but it is
meant for burning in the kiln. It has always cleaned up well in the
ultrasonic.

Give it a try? Let me know how it works for you!

Hello Allan, I use for years iron oxide. This is also called paris
rouge for pollishing. Scrape some of, and solve it in white spirit,
or therpentine or else. as a thick paint.

This can be used as antiflux. If you sollution boils and gets on
places you don’t want; use less solvent, or heat up slower.

You can use red rouge, scraped off your polishing bar, and thinned
with lighter fluid or turpentine (NOT turpenoid, or turpenoid
natural). But note that it is ferrous in nature and should be washed
off as much as possible before pickling to avoid copper plating.
