Maid O'Mud on thu 30 aug 07
I haven't seen a reply on clayart, so I'm thinking the note got lost
in cyberspace. This is a re-send. Hopefully someone knows the answer :-)
I've been using maccaloid for over a decade, and am finally running out.
Amongst the treasures I've acquired over the years from people selling
out their studios I found Vee Gum T. When I make my glazes,
I usually use 0.25% mac, up to 0.5 for F4 heavy glazes. It has always
worked great.
So, the questions are:
how different (chemically/physically) is mac from VG T?
What % should I use to replace the 0.25% of mac?
If I'm topping off a glaze that's gotten low, can the 2 mix??
Thank you :-)

I see macaloid listed in catalogs as veegum. I think it's the same
thing (maybe veegum is a brand name?); I use them both and they seem
to be interchangeable.

Hi Sam,
I suggest you try the same amount - or call Frank and ask him.
I don't think the chemical make up is of any cocern - it's such a small amount.
Wish I knew the answer - let me know what you find out - RR
