I am new to the forum and need some help. i have built a 6" j tube from loose stacked firebricks and it work great. Now I would like to mortar the bricks with clay slip. Here is the problem. I have several different local clay soils to choose from. One soil is 66% clay and 33% sand, another is 20% clay and 80% sand. The last one I have tried has so much clay in it that it won't melt in water. I have dried the first soil and hammered it into small pieces added some sand and it made good slip.I know this is the long way to get the question so here it is. Is there anyway to process the pure clay soil without drying it first?
Merry Christmas to you all,
