I had looked at Helmer awhile back, something about iron content ( do not recall now.) Let me revisit that, TY.
From the notes I have taken: macaloid seems preferred in stoneware, and V-gum in porcelain. Not exactly set in stone rules, but I have noticed that preference.
Edit: Lou, just hit me you stated 1/2%? Do you think V-gum is that much more plastic than macaloid?
its not the vee gum only its the vee gum plus DR-10 (drag reducer 10) the helmer body has a work ability/feel to it
