karla Posted December 1, 2020 Report Share Posted December 1, 2020 Hi everyone, We have a Shimpo vacume pug and started adding a splash of vinegar to slurry water to each bag of offcuts to be pugged, now it looks as though we have busted a seal, is there something else we can add to keep the clay plastic? thanks a million Hayley and Karla Link to comment Share on other sites More sharing options...
oldlady Posted December 1, 2020 Report Share Posted December 1, 2020 why are you using vinegar at all and not simply water? what made you try this in the first place? Link to comment Share on other sites More sharing options...
Min Posted December 1, 2020 Report Share Posted December 1, 2020 Keep your throwing water and slop from your splashpan and add that back into the clay scrap. It's the fines that make the clay plastic, when you throw clay some of this is removed in the slip that is generated. Alternatively, @glazenerd suggests using a blend of 80% OM 4 ball clay, 10% silica, and 10% nepheline syenite for stoneware, using 1 cup of dry mix blend to 1 gallon of slurry then adjust amount as necessary. For porcelain he suggests using 50% Grolleg kaolin, 25% nepheline syenite, and 25% silica together plus 2% BentoneMA and use 1/2 cup of this blend to 1 gallon of slurry. His full article is in the June/July/August issue of CM. Link to comment Share on other sites More sharing options...
Mark C. Posted December 1, 2020 Report Share Posted December 1, 2020 I just keep the slop from splash pan for my porcelain handy at mixing time and add a tad per mix. Bag and let sit a short while. Link to comment Share on other sites More sharing options...
