BACHO Posted February 22, 2021 Report Share Posted February 22, 2021 I'm thinking of purchasing the Bluebird 440 pug mill and I was wondering if I pug Laguna B-mix there would be corrosion issue ? Link to comment Share on other sites More sharing options...
Mark C. Posted February 22, 2021 Report Share Posted February 22, 2021 B-mix is a white stoneware not a porcelain so my guess is no issues You could PM glazenerd as he is the expert on bodies The issues are with low fire talc bodies and Porcelain bodies This machine is a straight pugmill only not a mixer/pugmill like Petter puggers or others welcome to the forum Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted February 22, 2021 Report Share Posted February 22, 2021 Hi @BACHO, I’m going to retitle your post and move it to the Equipment section of the forum. It’ll get more views and answers that way. Link to comment Share on other sites More sharing options...
Stumonster Clayworks Posted March 30, 2021 Report Share Posted March 30, 2021 @BACHO I discovered through help in the forum that long term storage of B-mix in an aluminum pug mill can cause corrosion where it pulls out salts and the aluminum reacts. Apparently it is a reaction with the Neph syn. I was told by the people at Peter Pugger that as long as it is mixed pretty regularly and continuously refreshed with new clay it shouldn't be an issue. However, they mentioned that cleaning every 2 or 3 months is not a bad idea. Link to comment Share on other sites More sharing options...
Mark C. Posted March 30, 2021 Report Share Posted March 30, 2021 My guess is the b-mix with Neph syn is mid range B mix you are talking about as its there as a flux. Like talc in low fire bodies does the same thing to aluminum. My VPM30 Peter pugger was used by high school with low fire body and is pitted -not terrible. I use high fire porcealain in it now and never clean it. Some day maybe I'll need a new barrel. I recencly bought a VPM 20 stainless machine used and will use another porcealain body in thatsmaller machine (high fire) I think the pitting issue is worse with low fire and some mid range clays. I have never seen or fely any aluminum in my clay. Link to comment Share on other sites More sharing options...
