I also recommend using a rubber spatula to get all of the glaze out when you sieve!
This glaze is loooovely, thank you so much for sharing ❤️
Thank you for sharing your method - such a beautiful neutral glaze, gives me a zen vibe!
Really lovely video, thank you so much :)
I tried this glaze and I love it❤️ its my fav from now on. Thank you for sharing this is precious 🙏🏼
Do we have to fire the glaze
@@Ziiyapathan yes
Thank for sharing
Love this video, making glazes from scratch seems much less scary now. Have you done a video on how you make your test tiles ?
Thanks you 😍
Awesome video! And hard to come by videos like this! Thanks so much for sharing 😊 would love to see more like this! I’m excited to check out your insta
There is more coming :)
This is really beautiful ❤ I see you added the recipe to the description, but do you have it up on Glazy as well? Would love to be able to save it to my favourites there
Such a beautifull video, like every post of you! ❤ I just love to see your beautifull work and i will try this glaze. Is the basic recipe a matt withe or would i have to ad somme zirkon or some tinoxid to get it white?
I'm only a 3.5 year novice potter and have never had an interest in mixing my own glazes. It seems super complicated, but then again so did pottery the first time I tried it. I wonder if that will change one day. I always wondered what the process was, so thank you for sharing your secret recipe and demonstration.
No probs! It’s very satisfying getting a successful home made glaze out of the kiln. You should give it a go
Loved the video!! Would you talk more about glazing applications? Glazing is my nemesis as a beginner potter. Grrrr….
Sure, I can do a bit of a demo next time I’m glazing. I really only dip or pour my glazes though, I’m not a fan of brushing or spraying.
Beautiful glaze! Thank you for sharing. Are you firing cone 10?
thanks for great video. Can I ask, if you did three layers would it getting whiter? i noticed the second layer did
Such a simple recipe for such a beautiful glaze wowowow I wonder what it would look like over my standard 266!
ahhh this glaze is cone 8-9, I’d have to change a few things but I’m sure it would be close enough
Do you fire lower? You can add boron to bring the melt temp down, just need to normalize the base recipe
@@MaeCeramics yes cone 5-6 I’ll try it!
Bellissimo
Hi! Love the video and the explanation. Do you always work high temperatura?
Yep I always have done. I have some pieces id like to make in terra cotta though so may lower it a bit for a few firings!
hii, can I change to color other than red oxide? Like purple maybe? will it change anything other than color from the recipe?
Do we need to fire the glaze at high or low temperature or just to keep it for few days?
Please reply
How can I make those black dots please?
Hi Lily! Thanks for that video! It does actually take the fear out of mixing my own glaze :D One question popped up at the end of the video: what material is making the glaze matte? And what is making a glaze shiny? Thanks again and have a nice rest of the day! :)
Yes, give it a go, it's really satisfying to take ownership of the glaze aspect of your work too.
It depends on the balance of materials - for example dolomite in a glaze will generally mean it will be reasonably matte, sometimes rutile can mattify too. Look up some matte recipes and give them a test.
My one piece of advice is just to make sure they're properly matte - that is they are fully fired. Often you'll find a 'fake matte' - which is just a glossy glaze that hasn't reached temp. That will make for an undurable glaze and should be avoided. You can test that by firing the glaze to a higher temp and it should not ever turn glossy.
Do you use city water or distilled?
Hi Lilly
This was such a helpful video to watch
I have two questions as a beginner ceramicist:
Can you please tell me the firing range for this glaze
How do you get the right density, I really struggle with how much water to add, some seem too thin and some too thick. Do you have a special method ?
Thanks 🥰🥰
Hey Olivia!
I fire this glaze to cone 8-9, 1265°c with a 20 min soak. If you fire lower you could experiment with adding a little bit of boron to lower the melting temperature.
As far as water goes, I don’t have a special trick, I just always try to do around 1:1 water to dry weight of raw materials. You can get special tools to find out the specific gravity of your glaze but I’ve never done that.
It should be around the consistency of double cream. If you aren’t sure, you can take a few batches of 100g of dry glaze, and try 80g water, 100g water and 120g water and so on to see how the consistency affects the finish. Make sure to label your test tiles if you try that :)
Hope that helps.
Did you have to put them in the oven at all or not?
Thank you very much for sharing, but could you please share a way to obtain different colours apart from Red
There are loads of recipes on Glazy.com
Great video.. thanks! When you clean your sieve, brush etc is it ok for the cleaning water to go down the drain? I don’t have a sink in my studio… just use bowls and my outdoor tap and dispose of clay water down my household drain (really minimal amounts of clay in case anyone worried!) but anxious about disposal of water with glaze traces in it.
Really good question! I should have covered this in the vid really. I don’t wash my tools in the sink, I do what you do - wash clean my tools with a sponge into a separate water bucket, let it settle, and the next day pour off the excess water. I do then one of two things:
1. If the glaze was just one colour, i pour the remaining glaze sediment back into the glaze bucket to use.
2. If it’s more than one colour, i pour it into a big glaze scraps bucket I keep by my sink. It has no lid and when full, it eventually dries out. You can discard of this when it’s dried or you can mix it into a mystery glaze (lol).
I hope that helps!
@@MaeCeramics fabulous! Thank you! Need to add a ‘glaze scraps bucket’ to my growing pile of buckets in my teeny weeny studio now! Great advice and love all your videos. You have a wonderful, quiet energy 😊
What does your firing schedule look like for this glaze besides the 1265c target temp and 20min soak? Thanks for a super helpful video :)
Something like 150c/h - 1050, then 80c/h to 1265c
Hi Mae, thanks for a great unscary step video! I am going to follow your recipe for my first venture into making my own glazes. however i only fire to 1220 so wondering how much boron/borax you would suggest adding to this recipe you're using here? thanks so much !
You can recalculate it on Glazy to have 0.15 mol% of boron. All the other proportions should stay the same. So if you add frit or gerstley borate you will need to lower the flint, feldspar and whiting a little bit so that the umf stays the same (except for the extra boron).
Do you have frit 3124?
That will give this:
28 potash feldspar
26 kaolin
21 frit 3124
14 whiting
11 silica
Same amounts of rutile, rio and bentonite.
Good luck!
If you use another frit/gerstley borate you will need to recalculate. Don't use borax :)
@@____Ann____ thanks so much for that Ann. I'm new to making glazes so no, i don't have the 3124 but can get some :) much appreciated!
@@Jo-wj7og you have another frit? It is not too difficult to recalculate with another frit.
@@____Ann____ thanks so much for your help Ann, no i have only just started accumulating ingredients :) i ordered a bit of 3124 as its not the first time I've seen it mentioned. its all very new and I'm not a chemistry savvy person!
Hi Lily! I fire at 1250 and soak at 30 mins. May I know how I can adjust the recipe? :) im still a newbie so any tip would help!
Hello! It probably doesn’t need adjusting as it’s only a few degrees - but you could try upping the temp a bit or make the soak a bit longer. Alternatively if you’re not able to do that but not seeing a nice melt, you can add some borate as a flux. Maybe 5% to start. This will affect the recipe as a whole so just make sure to normalise to 100% when adding something (google how to do this if you’re not sure!).
