I'd like to learn more about slipcasting, but am having trouble finding information on it.

Google slip cast ceramics-
1,230,000 pages to read-that should take awhile to digest.

What do i need to add to my cone 6 stoneware clay to make it suitable for slipcasting? I have a trash can full of waste clay that is not worth my time to wedge.

I usually buy slip when I need it. I never make it. However you can 'Google' 'Paul Wandless slip making'. He has a method of making your moist clay into casting slip. You may get the same info here on CAD; try a search.

Try doing a library or Google search on 'mold making for ceramics' and there you will find slipcasting information.

You can make most clays into a slip body but it will not be the best slip body-I suggest if you want trouble free slip results us a slip body made for slipping. Waste clay is not great slip clay-You can use it but it will take some time and test results it may work out and it may not. I have either made slip clay from scratch dry materials or bought slip clay in dry state but never tried to make whatever I was throwing into a slip body.

John B. Kenny's Complete Book of Pottery Making has directions for making casting slip that involves a 10 day process. This is an old book from the 1950s.
It begins with a dry powder clay recipe plus diffloculent additives and proper blending of 10 minutes three times /day for 10 days. I used this process and it was very successful . I was able to make slip for particular clay bodies.
