My bisque ware which I subsequently smoke fire is naturally not fired higher than 950C. I have been trying to attain an ultramarine blue which would contrast nicely with the deep black of the smoke firing. But because of the low temperature, I find that using a cobalt slip does not fully develop the colour. Does anyone have any idea how I could achieve a deeper blue slip?

You could try mason stains or underglazes.

Thanks Chris. I must admit that I have never tried mason stains, but that might well be the way to go. Presumably I could add them to a slip in the usual way?

Visit the mason website, look at the color charts and select stain that is recommended for use in a clay body.
The blues I have used get darker the higher they are fired. Your base clay color for the slip should be very white.
I just mix clay, water and stain in my studio blender ... but I am sure others have actual recipes.
