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

I thought a vacuum pug mill did the same thing as a months ageing without the months worth of time. Maybe without the slight souring from bacteria.

I had the opportunity to try some vacuum clay compared to same body

blunged aged and filter pressed..... The later like john b stated is much nicer

Check out the helmer clay body..... It uses a very lo wpercentage of vee gum...... And a " high tech" plasticizer. Dr-10 or drag reducer 10. It's quite plastic! I really like the feel and quality of this clay...... It's quite unique compared to the other porcelains I've experienced.

I have experimted with these plasticizers ....
My last test had les than extremely low percentage of platiccizer. Under 1/2 percent. Yet very plastic.. Would prefer to pm for further info

couple things


maybe your throwing with clay too  wet as in added water


your clay body is too dry.  making it difficult to pull


your not coaxing the the clay with enough authority


i will occasionally use tools to pull


try not using sponge

try different parts of hand.fingers
