Dear colleagues, I have to make a decision as I could have a Venco Super Twin in a few days here in my studio what would normally take months to be delivered and I have a big order of lots of plates to throw. In my research about pugmills I have come as far as that I think I have to decide between buying a Peter Pugger vpmss20 and a Venco Super Twin, both stainless steel and de-airing. I throw porcelain and run a studio production, means around 2 tons a year, getting more (sorry, I'm not a native speaker)... I'll need it in the first place for replacing the wedging of new porcelain clay as I find this extremely power- and timeconsuming for production. I let the wet material dry a little bit down to have a stiffer clay for throwing thin bigger pots. That means the clay has stiffer parts outside from the drying and softer ones inside even if I dry it slowly under a soft fabric to avoid too fast drying. I hope such a machine could mix and de-air it for having a homogen porcelain body ready for throwing. That's what I intend mainly. To reclaim crap is also an idea but not really important as I can sell trimming crap for a small money to someone who re-uses it for small sculptures. i know in stoneware de-aired clay is a gorgeous thing for throwing, but porcelain is different and it seems to absorb air whenever possible so the vacuum effect might be a problem? What I have heard about the Peter Puggers: Some potters have problems with porcelain coming out with no plasticity. Also heard a rumour that the pugging chamber of the PP is too short for good de-airing. The advantage of PP seems to be that the clay can be stiffened or dried down easily and that any stiffness doesn't seem to be a problem at all as the mill is very strong so it won't stop with stiffer clay. About the Venco: the twin spiral shall have a quite well mixing effect but the de-airing pump shall also not be so good. Another disadvantage of the Venco is that I heard it stands still if the clay is too stiff and you have to open it to pull the clay out before going on with softer clay. I'm afraid I will have spent so much money to have small air bubbles in my fired ware what must be quite horrifying and / or that I have a machine that stops when i put a bit stiffer clay for bigger pots into it. It would be SO GREAT if anyone working with porcelain with these machines could share his/her experiences... thanks so much, claude
I took pottery in college as a hobby while completing my degree. I loved it so much that I have slowly been trying to put together a home studio. I would like to get a pug mill/mixer so that I can mix my clay from scratch (dry components), reclaim used clay, and use the de-airing features to save time and work. I am looking into the Peter Puggers, specifically the VPM-9SS and the VPM-20. Is the stainless steal worth the extra money (in the case of these two it would be $100 extra) and a smaller hopper? Or should I go for the bigger hopper and $100 cheaper with the VPM-20. Though I have thrown on a wheel and sculpted for years I am somewhat new to this piece of equipment and any information would be appreciated!!
I've been using my new Peter Pugger VPM 9 for a few months now. The clay that first extrudes from my pug mill always has green particles on it. It's obviously left from the cap when I take it off of the clay as it extrudes. I have contacted the company who said it may be a reaction from the clay I'm using as it comes into contact with the cap and to stick that clay back in the pug mill. The clay with any green on it does not burn off but stays green on my pots. It's almost solid pieces of green that I can pull off of the clay. Has anyone had this issue, or have any advice? Thanks!! --- Margie
