Watched 1000s videos, read lots of books. This is one of the most comprehensive view to slip casting. Thanks for sharing & caring🙂🙃🙂

[@rebekahbogard3322]

Ohhh, wow! Thanks for the super thoughtful and inciteful comment! I really do care! And I want to educate/demystify it for the people with questions.

Thank yo SO much for making this! This is a wonderful tutorial refresher!

Finally, an answer to why I have such difficulty removing complex platters from their molds. Thank you so much for this video. I'm off to get me some Darvan 811, and perhaps an air compressor!

[@chriseadie2359]

Thank you for this! The only thing I'll say is that it isn't really magnetism that makes a deflocculant work - I think you're conflating magnetism with the electrostatic effects within a slip. Magnetism is the moving of an electric field causing repulsion or attraction. Zeta potential is the electrostatic repulsion between particles and a liquid in a suspension. Deflocculants increase this electrostatic effect, keeping the particles separated and allowing them to flow.

[@chriseadie2359]

Also wow that piece at the end is beautiful

[@rebekahbogard3322]

Hi Chris. Thank you so much for your generous comment and clarification regarding the difference between electrostatic charges and magnetism. It is a very good point to make! I do tend to over-simplify when explaining this issue, and maybe I am dumbing it down just a little too much. Thanks again for bringing this to my attention! And thanks for the compliment!

[@zakmenzou7160]

Hello, thanks for sharing all this informations, your creativity is so inspiring. Indeed I want to know how long should I let the plaster mold dry after using it, to reuse it a second time, thank you.

[@rebekahbogard3322]

I usually let it dry overnight. So, I will cast first thing in the morning, release it in the afternoon, and leave the mold to dry overnight before doing it all over again the next day. If a mold is small and if I work a long day (10 hours or more), I have found I can get two casts in one day and am able to let it dry overnight. I live in Reno, which is a very dry climate. You can always put it in front of a fan overnight if you find it is still damp the next morning. Good luck! And thanks for the compliment! :)

I'm thinking on making a single pour mold could you please make a video on the single pour mold Please you are a very good teacher ty

[@rebekahbogard3322]

Thanks for the very nice compliment! A one-piece mold is a great place to start if you have never made a mold before. I honestly don't make many of these. But if an opportunity comes up, I will do a video on it. Thanks for the request!

Excellent video! Would you mind telling me where you got the Humming Bird mold? I have been looking everywhere for one.

I made it myself. You can see me making it on my two-part mold making video.

@@rebekahbogard3322 thanks for the reply. Looks like I have a bunch of videos to watch!

[@lauraarias4222]

Love you very details video with such a good information. I have a couple of question. The slip porcelain is the same as clay? Can clay be made into slip porcelain ( liquid to pour). Wondering as i would like something to pour but them add details later on. I read somewhere that slip porcelain need to be the same as the liquid so they can merge in the baking process. What brand do you recommend that offers both. Thank you so much in advance!.

[@rebekahbogard3322]

Porcelain is a type of clay body that is white, pure, and high-fire. You may also turn this clay body into a casting slip. Both are very difficult to work with. I primarily work with a low-fire earthenware clay body as well as casting slip. I sometimes cast with a "mid-fire porcelain," which is challenging and difficult to work with. If you want to use a porcelain casting slip, I highly recommend you simply purchase pre-made slip, which is what I do. I order from Clay People and get the "Pearl" casting slip. You can buy it by the gallon. But can also buy it from most places. bigceramicstore.com/products/laguna-clay-cn4110g-oriental-pearl-porcelain-casting-slip-slip-cone-5

[@user-zc1rk4bh4u]

Question! How long until I can use the mold again to cast my next mold? Thank you!

[@rebekahbogard3322]

I usually cast one piece a day. I cast it, open it, and let it dry overnight. Sometimes I can cast it twice a day (especially small ones). Experiment and see what works for you. :)

[@WadeMcLure]

I just started doing this, got a bunch of molds for free... Wasn't sure what to get so I picked up some of that "Perfect Cast" Poured it in a small x-mas Santa ornament, left it in for 40 mins (cuz that's what the instructions on the bag said) and it got stuck in the mold... I was finally able to get it out but it stuck to a couple small details of Santa's beard and broke them off :-( Was it the stuff I used? Or did I do something wrong?

Do you have to put this in a kiln following?

Yes; you are correct. Once it is dry, I bisque fire it in a kiln.

Thanks for the comment! Sorry I can't read it!

[@user-fe8el4hx4n]

You can't time a cast . It depends on the weather, the dampness of the moulds and the viscosity of the slip. Also remove the scrap before you open the mould. One more thing PUT some overalls on.

Thanks for the suggestions. But I don't do any pressure casting.
