enbarro Posted February 14, 2014 Report Share Posted February 14, 2014 Hi, I mostly singlefire to cone 04-03 and brush my glazes on bone dry pots. I ordered vee gum t and have bentonite. I’ve read I should add no more than 3% bentonite somewhere and somewhere else to add 5% of bentonite when single firing. Can someone with direct experience on the matter help me out? I know I need to try this on my own, with all the variables I work with… still I might save quite a bit of time with some help. Thanks. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted February 14, 2014 Report Share Posted February 14, 2014 5% for single fired glazes on ^ 6 single fire . I don't know about low foe. Marcia Link to comment Share on other sites More sharing options...
enbarro Posted February 16, 2014 Author Report Share Posted February 16, 2014 Thanks! So, 5% no matter the glaze composition? Was getting the Veegum T a waste of money? Any help related to Veegum T for brushing glazes, even if not single fire is still welcome. I've never tried it before. Is it stronger or weaker than Bentonite?

neilestrick Posted February 16, 2014 Report Share Posted February 16, 2014 I prefer VGT to bentonite for brushing glazes. 2-3% in combination with gum solution makes a nice brushing formula. Make gum solution by adding 2 tablespoons CMC Gum and 1/2 teaspooncopper carb (preservative) to a gallon of hot water. Let sit overnight then blend well. Use the gum solution in place of 1/3 of the water in the glaze. Link to comment Share on other sites More sharing options...
enbarro Posted February 19, 2014 Author Report Share Posted February 19, 2014 Thanks Neil! I received the veegum t today... I think I’ll start with 3% veegum without cmc. I’ve never been able to make the cmc work… What do you think it adds to the mix? Link to comment Share on other sites More sharing options...
neilestrick Posted February 19, 2014 Report Share Posted February 19, 2014 The CMC is what will really make it brush well. It allows the glaze to hold more water so it flows onto the pot better and doesn't dry immediately when the brush hits the pot. Also adds a bit of sliminess for flow. You will have to experiment with how much gum solution you like in your glazes. Let your wet glaze sit overnight and blend/blunge well to incorporate the VeeGum T.
