[Maria ten Kortenaar] Hello, welcome back. Today, I will be working with porcelain and showing you a technique called ‘nerikomi’, which involves creating marbled porcelain. I will demonstrate how to build a pot using this technique, starting with a block of porcelain that displays a gradient of colors from dark to light. At the end of the process, you’ll see the transformation from a messy-looking pot to a beautiful finished object.

First, I’ll create a new color for the gradients. I’ll make a small well in the porcelain and add the pigment. I’ll knead it until the colors blend seamlessly. Next, I’ll make equal strips of the colored porcelain.

I’ll arrange these strips in an alternating pattern, going from dark to light, and then stack them to create a block. It’s important to press the pieces firmly together to ensure a solid structure. Once the block is complete, I’ll flatten it into a slab.

Now, I’ll cut the slab into smaller pieces to create the sides of the pot. To assemble the pot, I’ll stack these pieces one by one, using black porcelain slip as the adhesive. This will create visible seams, adding an interesting visual element to the final piece.

Once the pot is fully assembled, I’ll let it rest for at least 24 hours to allow the colors to meld together. After that, I’ll trim the bottom to create a level surface and make a perpendicular corner to ensure a solid foundation.

To construct the bottom of the pot, I’ll cut a circle with a circumference of 45 centimeters. Then, I’ll attach small blocks of porcelain in a pattern, using yellow for some and larger blocks for others. I’ll use black slip to join these pieces, emphasizing the seams.

Once the pot is complete, I’ll let it dry for several days until it reaches leather-hard consistency. Then, I’ll scrape away the excess black slip to reveal the intricate pattern underneath.

Finally, I’ll fire the pot in a kiln at temperatures between 550 and 1250 degrees Celsius to ensure its durability and water resistance.

  1. yes, but where did the yellow-orange lines come from?they were not present when the video began the process. It is a sham that the video cuts out the steps in the process because those steps are essential to the building.

  2. Can you tell me what body stains you are using please and where do you source them? You mentioned China ? I love your work. It is very inspiring . Thank you for sharing ❣️

  3. Feedback for channel. the content was good -Thank you. The demonstration was quite clear, even with the language barrier. The editing was awful. It was really distracting. All those interjections and sudden changes of camera angle weren't necessary and actually made it really uncomfortable to watch. I tried to stick with it but it actually made me feel nauseous.
    On the one hand this makes me sound like an oversensitive lunatic. On the other hand -count how many times the scene was changed. No filmmaker would consider it.

  4. Fabulous! I am not clear on 2 things though. When you lay down the white slab, it should be solid on finished piece, but your nerikomi goes entirely through on piece that you are supposedly making. Also, how do you clean the black slip off of piece? Sponge or scraper. Please, please, please continue making your videos as they are amazing.

  5. fantastische video! ik keek m'n ogen uit en gaandeweg beantwoorde Maria alle vragen die in me opkwamen ("hoe lang rusten, waarom rusten, waarom handschoenen"). Echt heel goed. En ook zeer inspirerend.

  6. As always, a joy to watch. Thank you again for making these videos. However I wish there was more details in it. It seems too fast at some critical stages
