How to cast a mould with liquid clay and create ceramic shapes. 

Very informative. I wasn't aware before I thought slip was slip for ceramic.

WONDERFUL VIDEO! I know nothing about ceramics. I came to RU-vid to find a video that showed what I had just read about in an article on deflocculation, rheology, & thixotropy. Your video did a great job of showing the things I didn't understand because of my lack of familiarity with ceramics! My background in chemistry could only help me understand so much before watching your video. Thank you!

Thank you, very informative, and now we understand more about why we get hotspots.

Great video, thank you for sharing. Very informative and lots of good tips!!

so satisfying to watch the unmolding :0

Thanks for sharing your knowledge,great tutorials 👍🏼

This is a great demonstration, thank you so much Mr.

Well I launched YT for a totally different topic and then found myself watching this. Not my hobby or business but I found it very interesting, informative and well presented. Well done and thank you.🎉

Thank you for sharing from Slovakia :)

This is a great video! Very informative, thank you very much!

Thank you - great video for me and what i need to have done in my pottery studio

Great tutorial! Thanks for sharing your knowledge.

Excellent video. Thank you so much.

Great video, thank you for sharing !

I subscribed a week ago, first video of you for me to see. . .thanks!

I am a DIY guy, and currently I have an antique automobile. A broken part on my transmission has forced me into learning a lot of this stuff, because I have to make my own part on my car transmission. Yesterday I attempted to make a mold using petrobond on my aluminum part. I learned very quickly that petrobond sticks to the aluminum Park that I'm trying to make a mold of. I spent all my money this month on my fixed income, on everything I need to do this, LOL oh, now I have to wait until the 3rd of next month to continue lol again. Nonetheless... ... learning what I am watching in this video is the Avenue in which I need to take next month when I resume my task... ... this is an absolute wonderful video teaching me how to make this part using ceramics. Thank you very much for your Productions, I have subscribed and will continue to watch all your videos thank you very much!

Thanks for the video.

good stuff

U R great work sir

Thank you for this demo. I have a chance to buy 300 molds but I know nothing about how do use the molds. This has been very helpful. next I need to know the next stage. will check back later for more videos. I think we have a Pottery club in my area so I.m wondering if I do go ahead making these if I can get them fired at the pottery club. Lots of things to suss out before making the commitment. thx again.

grew up using that slip machine, want to make dishware out of my homes natural clay on the property

Excellent video for a novice to watch.

Hey buddy. Good job creating all of that and making something out of “nothing” in a way.. just a muddy liquid into a beautiful product

figures are very good

I'm new to the ceramics world, my mom and I got lucky and bought a ton of molds and a kiln as well as paints and I believe pre-mixed slip? It came in jugs, and so I am a bit concerned for creating a proper consistency. I don't have a fancy mixer set up, is there a way to mix slip by hand and then determine if it's appropriate consistency for use within the molds? I don't imagine the jugs of clay and water will have gone bad, it's just clay and water after all, but I do imagine we will have to spend some time on properly mixing it and playing around with pouring it into the molds by hand as well as experimenting with how long each mold takes to set. I believe all our molds are plaster, and I anticipated that they'd take days to set so learning it could be on a timeline more so of hours was quite the shock. I have no idea how low to let the slip go for most of them, and the fellow who sold it to us never quite hammered out the specifics himself. We also have no idea what the type of clay in mixture was used, but I hate to let so many jugs go to waste so we'll use them to practice before making better pieces. Thank you for your video! It has been very helpful.

Hi, Thankyou for this wonderful video and explaining the whole process. I was wondering if for high fire stoneware clays we can do the same thing and make molds for the pots/utensils we want to make. Do you think it would work? Or only pinching is the right way to make it?

Great video! And I like your blunger and pump machine. Can you tell me who made it or where you got it?

How would you do this to make vessels for liquid? As in a specific wall thickness?

hi sir! good products you got there! i wish to do it my own, may know what material u used to make the mold? plaster moulds ya?

That was very simple to understand. Not yet slip cast, but have just ordered my first mug mould. When do you take off the lines on the clay.

Great tutorial. Would like to know what is the mould material are you using for casting wet clay?

Thanks for your lessons. Am looking for a toilet mold. Any recommendations. Thanks

Could you please make a video that shows how to produce the plaster mold. Thank You so much

This is a really interesting method of combining a traditional material and modern technology. It's made me think - could something like clay (or liquid chalk, plus some aggregate) be used to build a house wall, using a similar methodology as a concrete pour?

Just wanted to ask you were you get the mould scraper from been trying to find them with no luck at all

Hello! I have multiple ceramic mold like the one on your video. What I would like to know is if we use quickrete or mortar in these molds, will it come out and the mold be reusable?

Hello! How do you make a mold of a vintage lighted ceramic Christmas tree without damaging the original tree? Can it be done with silicone? I can't find any tutorials online. Thank you.

great video. How would I reconstitute the clay off cuts.

I am quite new to a slip casting technique. Have made several plaster molds for casting porcelain. And had some success, but recently I have noticed that some of the greenware gets tiny pinholes and then, (because some cups doesnt have it) there are SOMETIMES also pinholes on the glaze. If i got it right, those tiny pinholes are the result of air bubbles or pieces of dust in the casting slip, right? But i wonder, do those pinholes influence the glaze? I am a bit confused, because some of the porcelain cups are not having those pinholes on the glaze and some do have. it fires hire than it should and moreover fires unevenly. pinholes on the greenware? I'm using the vacuum matching,but my slip viscosity 1200

Awesome vid thanks so much @hobbyCeramicraft - this huge contraption you're emptying your slip in, poring back slip and that pump thingy to fill up molds. What is it call? I would definitely like to invest in one down the line xx

is it true that clay shrinks by an average of 10% ? when completely dry. And do you ever do push moulding, are there any limitations on the amount of detailing (could an Alien creature as in the film, be cast this way) barring in mind this is just clay?

Hi can you help me build a custom plaster mould for a project. i basically need a concave disk 5 mm wide is good enough but size 650mm *650mm.

Thank you, very informative. How do you know if your slip is too thick? I'm using Chromartie 1075 White Earthenware, with a small, baby's shoe mould. After only about 5 mins the slip is too thick to pour out. Should I thin it somehow?

Do you put a coating of something on the inside of the plaster mold before pouring the slip into it to keep the clay from sticking?

Excellent video, after removing the piece of slip from the plaster mold, how long should I wait to use this plaster mold again? thank you so much. :)

Hello, Great video, I just subscribed. Please tell me where I can have a mold made? I want to have an Egg pitcher mold made, size 34" x 45". Any Idea on cost for a mold that size? Thank You!

I am learning calyz and body silp. Teach me plz

how did you create the pasture molds in the first place?

I have a mold for a chess set and the kings are about 5 inches tall, so small pieces. I would like each piece to be as heavy as possible so is it ok to make the men solid by adding more slip as it goes down ? Will they crack durring the firing if I do this? Most likely I will leave a small air pocket in the bodies put the heads , sholders and arms will be solid. Thanks

once you remove from molds do you cover them to dry or just air dry

Where did you get your strap belts for the mould

Please can you tell me sir How i make liquid cly

Hi, thank you for the video. When would you have the time to share the video how to reclaim the clay and prepare the slip?

Could you tell me where you're from? I buy slip from companies that make slip. It is so thick that you can't pour it. If you do stir it down until it gets more liquid, it thickens within minutes and you can't get it to drain. I stir and shake and carefully take a dowel and try to make it drain. I don't know what to do. I have made slip in the past and I can make it work better. I'm not setup to make it all the time for myself so it's best for me to buy it premixed. I think there are ingredients that by law the companies are not allowed to put in, because years ago, it was always wonderful . I have been doing ceramics for more than 50 years so it's not like I'm a novice. I teach ceramics at one of the rec centers even at 75. I do the pouring but am so discouraged by the slip that I feel like throwing in the towel. Thanks.

should you not score up the 2 pieces of clay? we did with the ceramics

Can you do this with air-dry clay?

What’s the recipe please? I can’t find this slip anywhere in the US
