What consistency should the clay to put in the pug mill be if you don't have a clay mixer?

The clay comes out the same as it goes in. The pug mill just mixes the clay more and vacuums out the air. It may feel a little stiffer as it gets more dense after de-airing.

Do you have to add grog to the clay that comes from throwing?

@@marilynjackson5752 No, you don't need to add grog. What goes in is what comes out. You probably have more slip in your throwing water bucket than grog.

@@robertbanker5319 Again, I thank you for your answer. We were wondering about this since it seems our clay isn't as easy to use for hand building after being pugged.

@@marilynjackson5752 By "less easy to use" I am guessing you mean the clay is less plastic - can bend less before cracking. A clay mixer or pug mill without a vacuum pump leaves clay full of voids, tiny bubbles of air and will be less plastic than clay that is bought in a box or wedged. The vacuum part of the process is what makes the clay plastic by making it dense without voids. Make sure you are getting a good vacuum. Put the first clay that comes out of the machine back through. Some students pug the clay twice, realizing that quite of clay remains in the machine.
