- This video will teach you how to turn your own personal clay body in to a slip casting clay body.
Part 2 walks you through the entire process on how I turn my clay body into a casting body. I break down the various steps the slip will go through so that you can recognize them why you apply this method to your own clay. At the end of the video, you will see my clay body recipe and an example of my artwork.
Part 1 will break down and demystify basic clay chemistry. It is important to understand this chemistry so that you can apply it to your specific clay body. • Part 1: how to make a ...
Hydrometer Links
My top two recommendations for a hydrometer are either the Laguna one from the Clay Art Center ($33.00) or the Eisco one from Amazon ($15.59). Having some sort of a plastic case is key for me because they are very easy to break, especially in a lab with students.

The Laguna hydrometer is the best bet for the price and is very easy to use. It comes in a somewhat flimsy plastic tube, but is much better than the cardboard sleeves that the rest of the hydrometers come in. Although the cardboard sleeves are sturdy, they don’t stand up to water, which is unavoidable.

You can’t beat the price for the Eisco hydrometer, plus it comes in an indestructible plastic case that is adjustable. So, when you break your Eisco hydrometer, the case will fit whatever hydrometer you buy to replace it. However, the Eisco hydrometer is somewhat frustrating to use because it is much longer than all of the other ones. The Eisco hydrometer has a much larger measuring range and is best suited for measuring lighter liquids (lighter than water). So, when you drop it into a large bucket or vat, it falls over because it is too long. But if you are just starting out and can’t afford the Laguna hydrometer, it will work well enough. Plus, the glass hydrometer itself is fairly thick and less fragile.

Below are links to excellent articles on slip casting clay bodies by Tony Hansen, who knows a great deal more than I do in regard to the chemistry. If you really get into slip casting, I highly recommend reading these articles. They are easy to understand, provide excellent tips, along with helpful problem solving solutions.

Thank you so much for all details of the process! I've learnt a lot from you. Really appreciated!
Wow! So much great information! Thanks!!!
This was soooo helpful!! Thank you so much.
The sculptures at the end are lovely! And the video is super helpful
Thanks for these 2 excellent videos. I finally understand what thixotropic means! Your explanation is so clear and straightforward.
Great video. I've made casting slip before but sooooo long ago. This was a great reminder and so well explained. Thank you Rebekah
Thank you for this lesson.
Fantastic explanation for a beginner like me!! So appreciate this information.
very good explanation . thank you
Gosh. This was so helpful!! Been struggling with my slip for a few days but especially your factors and demonstration for perfect slip behavior helped me defeat my seemingly unwilling slip! Thanks so much!
Thank you for your excellent instruction!
Thank you very much
Great information.
Very 👍 👍 well done.
thank you for this video. Ifyou have a wheel you can easily set up a jig to keep stirring the clay for 12 hrs on its own.
Excellent and well articulated, with proper terms and concepts.
Thank you
How about using a fixed-size measuring device of a known weight? Scrape the top with a fettling knife after filling and wipe the outside. You'll get repeatable amounts of slip. Tare the scale or just subtract the known weight. Very accurate results. Thanks for your good work. Aloha
Thru this process I found it hard to major using my majoring cup but I trust my majorment as my deflocculant allows the viscosity of my majorments to align
A vibrating platform is necessary to measure specific gravity in a thixotropic fluid. Liquefaction is necessary to allow buoyancy over drag.
