@@AmeliaJohannsen MAESTRA! Hace muchos años trabaje la "cuerda seca"...ya me olvidé...si pudieras explicarlo en español...sería genial! El color, es cristal,,..o después le das el banco de cristal?

@@musi1musi264 Hola! Si claro, ponte en contacto cuando estés por Barcelona! El color que pongo en la cuerda seca es esmalte. Hay más videos en español explicando todo el proceso (aquí hay uno ua-cam.com/video/9qXUke0Gv8Y/v-deo.html) Y para el moca, va sobre barbotina (tiene que ser muy alkalina) y después pones el esmalte encima. ¡Saludos!
Very interesting technique (Cuerda Seca). As I'm new to ceramics, an doing much experimenting, I'm tempted to try to achieve a similar look using colored slips on greenware. I love the black outlines delineating the patterns and designs. Thank you for such a useful video! 😄
thanks Amelia. Well done video, very clear and concise. I've been doing ceramics for a couple of years, recently got my antique Skutt up and running. I'm interested in pursuing anything that expands my knowledge base and toolset. Both of these techniques are very interesting. I'm not sure my freehand drawing skills are up to Cuerda Seca but I'll give it a try on some simple designs I've developed. I like the idea of incorporating nature into my work. Mainly because the way things are going ceramic representations of nature may be the only thing left. Anywho, thanks again. Tom in Oregon
Thanks Tom, I'm glad you enjoyed the video! Great that you're getting back into ceramics...it's a wonderful way to disconnect with the chaos and reconnect with nature. I'm also spending lots of time learning and getting a home studio set up. Covid and motherhood have both made working from the community studio impossible right now. I hope to share more videos when I can and visit my home in Oregon in the not too distant future ;) Wishing you all the best!

Hola Amelia, muchas gracias por compartir este video. Me encantó el resultado final. Los platos decorados con la tecnica de cuerda seca son aptos para comidas? Por ejemplo el sushi o frutas con piel? O embutidos?
Hola, gracias y me alegro que te haya gustado. No, desafortunadamente estos platos no son aptos para comidas. Por lo menos, la receta que no he compartido no lo es. Sería interesante investigar una manera de hacerlo para vajilla👍
Hola Amelia, I am from Istanbul and we say "Çini" this technique in Turkish. İznik is famous for Çini. You can see the examples on the internet. :) Good job, Thanks for your video.
hello Amelia I wonder if this techniques can bes used on tableware. I loved the video en I'm gonna try it anyway, also when it's not suiteble for tableware!
Hi Lydia, I hadn't heard about using tinted wax, but it makes perfect sense that it would work as well. I haven't used wax in many years because I always seemed to drip it where it wasn't wanted ;) Let us know if you try it and how it works out!!
Thanks Céline! You're right, there are many, so feel free to use what you have easily available in your area. Here in Spain, I'm using transparent boron crackle glaze made by Prodesco for my frit.
Thanks! I prefer single-firing when possible because it saves energy (and time, sometimes). It does take some practice though and not all glazing techniques are valid.
@@AmeliaJohannsen Cool! I'd like to learn more, and make my own studio one day. Maybe when the virus mayhem ends I can go to your place in Spain to take classes!
Hi Lisbeth! I generally don't do anything to the bottom of the plate if it's an artistic piece to hang on the wall--I leave it plain and unglazed. The glaze is the decoration I use between the black lines, as you see in the video. You can use a paintbrush or a pear to apply the glaze.
Thank you for this video! I've only been in ceramics for a year. Two questions; what is frit? And, are the glazes you're using underglazes, or regular glaze?
Hi Julie, I'm using regular glazes in the video. And here's a great description of what a frit is: ceramicartsnetwork.org/ceramic-recipes/reference/frits/#
I was very excited about mocha diffusion and tried it with manganese dioxide. Worked well and bisque fired well. Then I applied the clear glaze that I have always used and fired to cone 6. All the dendrite type extensions disappeared, and I am left with 2 pots with (unfortunately) ugly blobs. Then I googled this issue and found a comment that indicated that pots with mocha diffusion cannot be fired to cone 6. I really would like this technique to work for me at cone 6. Do you have any helpful hints?
Hello I loved the sharing, however I don't speak English very well, it would be possible to send me the recipe from the beginning, which material you used to make the dark liquid (black), I thank you very much for sharing.
Thanks! The reaction at work here is the separation of oil and water. But ceramic is the only application of the cuerda seca technique that I'm aware of.
Hola Maribel! Trataría de usar lo que tiene fácilmente disponible en su área. Para mi frita aquí en España, estoy usando un glaseado transparente de boro producido por Prodesco.
Do you have a recipe you are willing to share for the slip? There are many out there, but knowing of one that works well can be a handy place to start. TIA!
Hello and welcome to the wonderful world of pottery! I'm glad you're enjoying learning and experimenting. For the slip, it's just water and clay. (Some people add a touch of vinegar for consistency, but I have never done so). For mocha diffusion, I will usually buy powdered ball clay and just mix with water until I get the right consistency (Similar to thick and creamy Greek yogurt).
hello from Crimea, I can’t find the right recipe for the outline so that the paint doesn’t spread. I want to use this method for silkscreen printing on tiles. please help me, I need your advice.)) Thank you
Hello, the oil in the cuerda seca mix should repel the water in your glaze. I'm very sorry, but I do not know enough about silkscreen printing to be able to advise you on this method. Wishing you the best of luck!
Thanks Wendy. I had never heard the term majolica even though I'm familiar with the style here in Spain. Just learning more about it now thanks to you!
Hi Shelly, most clays are alkali. You need to be careful mainly with porcelain and and clays where a frit has been added. What we're looking for is the reaction between the alkali clay and the acidic pigment mix. I've tested mocha diffusion with slips made with ball clay and kaolin, as well as with a commercially purchased slip, and they all worked well with beer and wine as the acidic component (they did not work well with lemon, vinegar or tobacco tea). As with any recipe in ceramics, you'll need to test the materials and ingredients where you live. Trial and error with different components until you find what works. Try making a slip with the clay you habitually use and see what happens. If you ever want to test your clay, the strips sold to test the soil in your garden can also be used for clay :)
Hi Cara, there are many different recipes out there and I have played around with interchanging different ingredients. As far as I can tell, any frit should work!
My friend and I have tried the Mocha diffusion and have run into a problem that we can not find addressed. The slip and mocha applied well. Then we bisque fired and the dust from the mocha is everywhere. It rubs off and in come cases, appears on pots that were not even toughed. We will clear glaze it later, but how do we keep the manganese from getting on everything
Hi Christi! I didn't run into this problem because I single-fired my pieces. Try adding a small amount of frit or transparent glaze to the mix to see if it stabilizes. Or try with different oxides. I usually use cobalt and iron oxides for mocha diffusion.
Hi Suzanne, you need a think layer of slip applied for the effect to work. I've never tried applying slip to a bisqued piece, but I imagine it would crack.
Regarding Mocha Diffusion, alcohol, acid and water: While the chemical reaction between the acids and the base (clay) create the cool fractal dendritic structures, the water, which is the "carrier" is going to change its properties due to the alcohol, which evaporates far more quickly, and is likely not absorbed into the process. As the alcohol leaves, the solution becomes more concentrated, which affects the patterns and the surface tension of the water. So the observed differences make sense. While a bit less fun, experimenting with different combinations of water to alcohol (using something like isopropyl alcohol (IPA)), might be worth the effort. Why less fun? Don't drink that kind of IPA - deadly poison!

Thank you very much 🙏. I was looking for the explanation
hello Amelia I wonder if this techniques can bes used on tableware. I loved the video en I'm gonna try it anyway, also when it's not suiteble for tableware!
Hi Linda, the cuerda seca technique is not suitable for tableware, while mocha diffusion technique is. I hope you enjoy them!

@@sherolie That would be great!
darn just came back from granada malaga and barcelona if i knew i would have passed the glaze is that normal glaze or specific
Any glaze will work!
Love ❤️ your studio
Hi Amalia. Thank YOU for your video. When doing cuerda seca, What do YOU do to the other side of the plate? If YOU are glazing it, how do YOU do that?
Hi Lisbeth! I generally don't do anything to the bottom of the plate if it's an artistic piece to hang on the wall--I leave it plain and unglazed. The glaze is the decoration I use between the black lines, as you see in the video. You can use a paintbrush or a pear to apply the glaze.
Thank you so much for your video! What type of support do you use for cuerda seca? I mean is this a biscuit firing?
For cuerda seca the pieces have gone through a biscuit firing before painting and glazing and then they're fired again.
@@AmeliaJohannsen Thank you!!
Thank you for this video! I've only been in ceramics for a year. Two questions; what is frit? And, are the glazes you're using underglazes, or regular glaze?
