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 that can be adjusted to work well at low and high fire temperatures. I'm wanting to find out what could be added to this clay body to make it a proper fit for cone 10 glazes and perhaps still work well at 04.
