Reclaim waste clay into Casting Slip for ceramic production.

Published 2021-05-26
Mixing dried clay pieces with water to create a fluid, usable casting slip with white earthenware clay.

Learn how to calculate your slip's Specific Gravity and understand when to add deflocculant to the mix in order to get to a workable consistency.

    To hell with skillshare and undemy and whatnot, this guy is an actual instructor, I've learnt so much from this video, thank you!
  • Your explanation of the target weight for specific gravity was a game changer for me. Made everything easier... I didn't need to get a precise 100ml beaker, I could do it with materials I already had on hand. Hugely helpful, thanks again!
  • Such a well explained video - thank you ! I'll be saving this to use again and again
  • What a wonderful video. Thank you so much. So many times people try to dumb things down, but I really appreciate the in depth lesson!!!

    Thank you so much for this! I initially watched some time ago and have just gotten into the practice of accumulating trimmings, organizing buckets etc. My trimmings have been slaking for several days and vigorous mixing is only resulting in clumpy mud. Came back to rewatch and see now i should likely add a touch of sodium silicate even at this early stage. Gonna give it a go and move forward! I truly appreciate your making this video. It is a much better explanation than most and have saved it for my future reference! Cheers to you!
  • I have been slip casting for 3 years using readymade casting slip. I have moved to Scotland where shipping is very expensive so I have bought dry pellets. This video have given me the confidence to learn how to measure SG. the best video i have seen- fully explaining. THANK YOU !!
  • Thank you so much for this video. It’s such a great resource for the ceramics community. Whenever people have questions or need help with their casting slip, I refer them to this video because it’s so well done and simply explained. I had also never seen anyone use the “any old bottle” method of measuring specific gravity, and now I use that in my own practice. Thank you!

    Thank you very much, you made it easier

    Thanks for the informative video. I tried this before from the video method and it worked like a charm. However, I recently tried making a slip with a new clay body. I added a little bit of sodium silicate, and it didn’t work as intended. It made clumps. I let it sit for a day, and now it’s a normal texture for an over-deflocculated slip (re-flocculated?), with a thick skin on top. I read that sodium silicate is better to dilute 50/50 with water, so i would be careful to dilute it. I also see washing soda in a lot of recipes as well.

    Thank you so much for this video. I am definitely going to give it a go now with much more confidence than before. I trust that I can do a good enough job and not waste tons of time of trial and error. Your information is worth gold to us. Does the same ratio work for stoneware clay? A huge thank you for what you do. It is very inspiring.
  • Measure 100ml water in plastic tube/Mark it and then take Slip up to the 100ml mark and it will give you the Gravity of the Slip. As per Mr Mikkel

    This has been very informative and as I already had a bucket of slurry from throwing on the wheel I have tried this out rather than using the dry clay pieces. Unfortunately my slip weighs too light and I’m struggling to correct it. Is it because of the slurry, which was very thick and gluggy when I started to use it, rather than using the dry clay added to water? I would have thought it would be the same? Can you advise?
