Hi all, I've posted about this local clay body before and I'm checking with the forum to get ideas on trouble shooting another issue. I'm firing to cone 05/04. The body itself is a beautiful lowfire body but after the bisque it gets a white scum on the surface . I'm not sure what it is that's causing the whiting but I think that the clay body would be gallery quality were it not for this blemish. I have sanded the surface after firing and the white can be removed. Obviously this is not a solution but it confirms that there is a beautiful clay body just below the surface. Any ideas
I've got this native clay that I've been working with for a couple years and it's a fantastic clay that fires beautifully to cone 04. When I first began testing this clay body i tested it at both 04 and cone 10. At cone 04 its a soft salmon color and it works great with cone 04-06 glazes. in a cone 10 gas reduction firing it turns black and seems to be too vitrified and brittle but there is no bloating. At this temperature it does not receive cone 10 glazes at all. All the test tiles I made with this clay glazed crumbled/shot off into hundreds of pieces. I know that there are some clay bodies
Hello all, As is happens I live in a desert. All the local earthenware clay I dig up is already dry and mostly free of impurities. Much of the research I've done regarding the processing of clay suggests that after drying the clay one should break up the dry bits into pieces then screen dry then re-hydrate to appropriate consistency. In my process I basically use the blunging process instead of dry screening. Aside from the drying process taking a couple days I cant think of anything that makes this process less viable. I've found this to be quite effective in weeding out the impurities.
