Thank you Matt & everyone at HCC for looking into this issue. It’s really reassuring to see a company who care so much about the quality of the products they supply to customers.
What cone are you firing this and does medium firing work? I did 05 cone, medium firing up tp 1800 F two layers of colorobbia glaze and it is melting, dripping. What am I doing wrong?
The terra bella glazes prefer a slightly lower temp, try a cone 06. The speed is less of an issue. Also, they are glazes in their own right, so do not need any glaze on top.
I like to do that when the clay is leather hard. If you leave until dry then you will make a bit of dust, so do when the item is still a bit damp and the clay flecks will drop off in chunks.
Not really, there could be many reasons.. Check the power from the fuse board is all good, then investigate into the kiln. If no power at the board, it is unlikely a component issue in the chamber.. check fuses in the kiln which are protecting the computer.. or maybe the computer itself..
Your content is always incredible the care you take in showing so many different variations is awesome and your thorough teaching with clear instruction is amazing
Will this process work with clay that was not originally made for splicasting? I reclaaim all my clay from throwing and what not and I am wondering if I could try out slipcasting by using those leftovers for starters by just buying a 10 euro bottle of sodium silicate...
I also make slip from regular wet clay. Oddly, making slip from blocks of wet clay is not as simple as from dry.. you have to really mix and mix to break down the chunks of clay to get a slurry.
I find sodium silicate works more effectively. The dispex is a blend of sodium silicate and soda ash, which balances the deflocculation preventing a cast being too brittle with sodium silicate alone.
The type of mould soap I have chosen over the years makes a big difference. Some that others recommended I can't get the hang of. I use a 'magical' liquid which I have no idea what is in it, but works for me.. so my advice, is.. if you are struggling, try a different separator.
Any hints or tips on raw materials like salt glazing or graphitic releases etc most videos are just product range based would be nice to get a more technical video on aspects of bulk production and alternative media's etc
Toilet.. sorry, no.. maybe contract a commercial producer and ask for an old mould. BTW, try painting a new toilet with glazes on top of the already glazed surface for a fun activity. Fire slowly though.. there's a lot of mass in that shape and needs even heating... (We've made a few.. cracked a few in firing them too!)
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.
@HobbyCeramicraft How hard would it be to create a glazed white ceramic rectangular vessel sink for a bathroom vanity? The only people on youtube creating such sinks use concrete, so I'm guessing it's a challenging process without factory equipment..?
Well.. i think durability too perhaps. Making a rectangular vessel in ceramics is not going to be particularly easy anyway.. the clay needs to dry at an even rate and fire at an even rate, which on a square or rectangular piece can be more challenging. This will also require a decent sized kiln to fire it in, which limits who could make it.. so, yes I guess.. makes concrete perhaps look easier...
Are your moulds dry? A wet mould can cause air bubbles in cast items. Check your s.g. is low enough and don't be afraid to use deflocculant to dcrease the viscosity.
@@HobbyCeramicraftit’s in the slip unfortunately… i get the sg right but i can’t get rid of them. Even bought a few different attachments for my drill and tried mixed on the lowest..
Generally for dipping we use colorobbia clear glaze, 004. The mayco stroke and coat colours, when used all over an item, do not require clear glaze on top.
Hello! Thank you very much for the so helpful video. Could I please kindly ask if it is possible to set up time exposure for the cycle steps? Not only for the last one. Thank you 🙏🏼
Nice demonstration and very well explained! I have one question about the mold: it has to be made of plaster? Or it can be made with ceramic? I'm thinking of making a mug and i was wondering if i could use a ceramic pot i have for the mold with no glazing. Thank you!
To make a casting mould you really need to use plaster in order to absorb the water from the clay which creates a clay lining. Ceramic would not work in the same way.
🎯 Key Takeaways for quick navigation: 00:03 🏺 To cast ceramic shapes, use liquid clay (slip) and plaster molds. 00:28 💧 Ensure the slip consistency is right; not too wet or too thick. 02:30 🚰 Be patient with slip flow; it thickens as it's mixed. 05:38 🏺 You can cast ceramics at home with basic tools like a jug. 06:19 🧰 Rubber bands can be used as mold straps. 07:50 ⏲️ The time to let molds set varies; monitor the slip level. 08:30 🌧️ Setting time depends on factors like mold dampness and previous casts. 10:04 🛡️ Thickness of the piece's clay film inside the mold matters for durability. 13:38 🧱 After casting, let the pieces dry; drying time varies with size. 22:33 🎨 Glaze-fired ceramics show hot spots if slip wasn't moved during casting. 25:08 🔥 Firing temperature depends on the clay used; bisque firing is around 1020°C. 26:35 🧽 Proper slip preparation is crucial for successful casting.
