Neat idea for this weeks video guys! You definitely saved the best for last!!! 😊
Absolutely gorgeous! Thank you for sharing your beautiful work
You always share such nice work! Something that most of us miss, or take for granted, is the time you spend on recording and editing your presentations, which are top shelf! Thanks for taking the time!
Thank you very much!
Those are beautiful! I have a pot i bought in the 80’s with crinkle glaze. It’s one of my favorites.🐝🤗❤️
Great tutorial!
I love your clear and no beating around the bush videos!!! 😁 Is it possible to use sodium silicate as a food safe glaze without crackle effect
Love the video even if I tend to cry in horror when I encounter 'crackling' glazes in my studio. 🤭 The white ink in the cracks over the blue underglaze appeals most to me. The dark inks tend to make a piece seem dirty to me, but that white over a darker glaze/clay might really be fun! Thank you for sharing!
I am the same Em. Crackling on my functional pieces is bad news but when used on decorative or sculptural work....WOW!!! I like the blue bowl too although the white wasnt quite bright enough a contrast for me. I think I liked the tear drop piece just because of that contrast, but they were all really fun to experiment with and I always like a good reveal as the ink went on and the cracks came to life. Thanks as always for watching!!
Great experiment! Seen this technique before. Like that. :-) Back in China, during Song Dynasty, it was the famous "Ice cracks", also known as open slices, is an ancient Chinese ceramic firing process. It originally belonged to a variety of Longquan celadon. The recipe was long disappeared, but 2 decades ago, a potter used 5 years of trial and error found the recipe eventually though not that I seen it-looks very alike. :-)
Cool!
That was great Anne!
Hey Jackie! Thanks so much!! It was so cool to see the inks spread into the cracks.
@@annruel1982 i know.. that was sooo cool..
So nice
A solution to my crazed pieces! Yay!!! 😃
Perfect!
Lovely effect. I’ve used a prepared brush-on glaze before, and although I got beautiful results, over time, say three months, the clay body absorbed the ink until you could barely see it. When I then applied more ink to freshen it up, there were far more cracks than there had been originally, so it wasn’t as appealing. The ink from the original application, having been sucked into the clay body, led to the second application being less crisp and defined. Perhaps a higher bisque would solve the problem.
Thanks...will have to keep an eye on that!
It's lovely, Anne. Do you think it could work with temperature around 1060 Celsius too?
Recommended by the maker of the glaze is Cone 5-6 (2145F minimum) or 1174C - good luck!
I love the way this looks-almost a Raku effect. Does the alcohol ink rub or wash off? If so, is there a way to fix it so it stays?
Thank you!
Once its in the cracks it tends to stay - I've not had any issues of it rubbing away. Thanks.
One question: do you still fire the piece after applying the ink please? Thank you.
No. I believe the ink would fire out of the piece. Thanks.
Wow, this feels like raku, but more refined.
I love crackle glaze.
Ann, Are your permanent inks the same as porcelain paints?😊
No. The ink used here is from craft stores...not food safe and will fire out if put in kiln. Underglaze (with clear glaze) paints are what you want for food safe and permanence!
Hi Anne, did the pinging eventually stop? I love the crazed surface but the pinging sound would drive me crazy 😂
It can actually take a day or so before it completely stops. When you have a few going at once it can get weird! :)
Do you think an oxide could highlight the cracks in this approach?
Hi FFSS60. Good question. Actually since the stain needs to be fired onto the piece to be permanent and the cracks dont show up until after it is fired, that would be a problem. You wouldnt be able to apply the oxide until after the firing and at that point you wouldnt be able to refire it to melt the oxide onto the surface because it would remelt the glaze and it would alter the spider web cracks. Does that make sense?
I’ve never seen anyone allow a glaze to sit in a pot so long. I haven’t made my own glazes but I have seen people dip their pieces. I swear there is nothing worse than that pinging noise when you aren’t trying to crackle a glaze!! It’s just the worst!! Lol. I LOVE the inks in the glaze! I unfortunately have quite a few crackled pieces that I’ll try to do this with. One last question, since these are alcohol inks are they going to stay? I wonder what a regular ink would do. I’m doing to go down and try a few different inks on one of the many crazed I mean crackled pieces that I have!
Hey Michele. If you have pieces that have the crazing to happen on them, that means that the glaze and the clay body are not good fits for each other. This causes a lot of stress when they are fired and the glaze cracks. the only thing you can do is to reformulate the glaze to fit the clay body. Sounds like those crazed pieces would be good ones to experiment on though. As far as the inks go, they are advertised to be permanent inks so I am hoping they stay permanent. I can tell you that I accidentally got some of the ink on the bottom of one of the pieces and it was not easy to get off. I tried sandpaper, diamond pads, and finally a grinder drill bit. i could get a lot of it off with the drill, but not all of it so it seems pretty permanent, although steadfast....I am not sure of until time passes and we just see. Good luck with your experiments. Let me know if you get a chance how it goes.
@@annruel1982 Thank you. I know why they craze but the very odd thing about my pieces is that I use the same clay and glazes and sometimes they craze and sometimes they don’t. It’s very frustrating. I buy pre-made glazes so I can’t really change them. I did notice that if I put a matte glaze on the outside of the piece and a gloss on the inside it tends to craze more often. But thanks for the tips, as always. I used the alcohol inks in mixed media and they were permanent, I just wasn’t sure they would stay in the cracks because it evaporates very easy but of course after thinking about it the inks are actually staining the area between the tiny cracks and maybe going as deep into the crack to stain the bisque so it will be permanent. I did try to add stain to several pieces that had crazed but the crazing was so small that I didn’t get very much color at all. But I was pretty tired when I tried it lol. Maybe I’ll try again. Your video did remind me that I have several low fire crackle glazes! Thanks as always.
@@micheledickey4066 Interesting. My thinking is that either the glaze WILL craze, or it may have cracks that may be there but are harder to detect. I bet if you put tea in the piece, they will show up sooner or later. If the glaze doesnt fit at one point, it is not going to fit at another time unless you alter the recipe or perhaps use a different raw material that had something else in it that changed the composition or something. That is just my experience. Thanks for the information about the alcohol inks. I have heard they are permanent, but the only way to find out for sure is time, right. Happy potting Michele! It is always a pleasure to talk to you.
Hi Anne! I love crackle glaze and will be testing this asap! 1 question that I don’t think I heard the answer to. I expected this glaze to run off your vase. Wouldn’t little clay cause this to be really runny? Did you find it quite stable? I could see that on the bottom of your vase, it appears to still have a definite glaze line. Thanks! Hoping I can use this without it running off a piece.
Hey! Thanks for watching. I was afraid it would run off the pot, but it didnt seem to run very much. It did crawl a little but the Wollastonite seemed to help with that. The only clay that was in the recipe was just the very little Bentonite I added to try and keep the glaze from deadpanning in the bottom of the bucket and that was only 1% of the recipe. In the end the bentonite didnt seem tohave any influence on the glaze but the epsom salt solution was the better solution. Have fun with the glaze....but remember it would never work on functional pots 🙂
@@annruel1982 thanks for the quick reply! I’ll show you my results ☺️ assuming it works 😀
@@madmonkeystudio-ajourneyin3220 Awesome!!!
Why is it that in the west crackle glazes are considered not foodsafe but in the east they use them for cups and other vessels that hold food?
That has been a topic of controversy for many years in the pottery world. There are so many variables (too many to discuss in this forum) but I lean toward being cautious. Thanks.
Do you think it would be possible to re-fire these with a transparent glaze over the crackle glaze to get them food safe?
The ink would burn off I believe
But you could perhaps use underglaze instead of ink, great idea.
Why is it not functional? I have read that as long as the clay is virtrified, it will hold water. Is it the ink that’s a concern?
There is a lot of debate about what is safe...I tend to fall on the "safer" side and not risk telling folks it OK functionally. Yes, the ink can run too, even after firing.
Do the inks stay in the cracks even after washing w soap and water? :000 Also are they food safe? Amazing video as usuall!
Hi. Thanks for the questions. As far as the inks go, we used permanent ink so I know when they dry they wont wash off. In fact, I accidentally got some of the ink on the bottom of one of the pots and used sandpaper to try and get it off without success. I also used a grinder bit on a drill and did manage to get a lot of it off but not all of it....and I was really trying. As far as whether the glaze is food safe the answer is a big fat NO!! I made sure to let everyone know that fact in the video as I would not want anyone to use it to eat off of. This glaze is strictly for decorative purposes only. This is not a food safe glaze and I wouldnt put permanent ink on food safe pieces either. The bowls and pieces we used to make this video were strictly samples for testing and will not be suitable for food.
Any glaze that has cracked is not food safe, bacteria will grow in the cracks.
will you please share this recipe?? Thank you
Thank you , I found #1 and #2 ,,,
Is this food safe?
I would not consider it so, but in many cultures and some potters are OK with it.
A bit of gum solution may help with the chalkie-ness
