Lets Make Glaze : 09 The results... the good, the great and the simply fabulous!

- Опубликовано: 22 окт 2024
- After the most surprising kiln opening I'm not quite over the shock of the success to be honest!
However when analysing the test tiles against each recipe and comparing to the results Joe at @Oldforgecreations achieved its clear to see I have improvements to make, and this is where I have no idea where to start!
I've no idea if Chrome Oxide and Chromium Oxide are one and the same - which may explain some significant variances. If anyone can advise Id really appreciate it.
Ive not used a hydrometer yet so no idea if specific gravity will impact some results. Plus Ive no idea what I should be looking for with this.
I definitely need to research which would be the best course to attend to understand this all more, and learn what ingredients have which effect and how to modify. I also want to attempt layering of these glazes and anticipate this will also lead to its own complications and challenges.
The journey that is never ending and forever a joy to continue.
I will try to add a further video shortly which will show how I apply a search facility on my digital filing cupboard, my test tile wall and upload all final pre and post fired images on Instagram.
Thanks as always for the encouragement and support on this fabulous journey, I feel I have only scratched the surface and have so much more to explore,

I noticed in the kiln you didn’t put a cone pack on the bottom darn it. Would have been nice to see if the temp was that different and if it didn’t make a difference etc. I saw on a few tiles that a few ran a bit more than the other. The transparent that goes over another glaze is just stunning. Can’t wait to see that one layered. I am so beyond proud of you for doing all of this and for your success!! Can’t wait till you get back.
Awh thanks Michele. The one I thought was a transparent was actually a crackle or snowflake, after closer inspection and comparing to the recipe it made sense. I think I need to definitely layer those to see the effect. Now I'm back home I don't know where to start lol. Maybe by restocking my studio with all my kit after the work was completed so I have a functioning studio could be a good start lol
Wow I am blown away. Sooo impressed. I started doing pottery about the same time as you and hadn’t even considered making my own glazes. But I’m so impressed with your results I think I am going to have to give it a go, providing I can get all the ingredients here in Turkey. Well done, you are a real inspiration 🙏👏👏👏👏
Sorry for delay in replying - been on a work trip. It was all a very daunting journey to start I have to admit, but once I'd started things seemed to make more sense. Definitely would recommend having a go, although Ive only made test tiles, let hope they work on actual pieces just as well LOL
@@FarForestCeramics still a bit daunting for me, besides I’ll have to research what ingredients are available here in Turkey. But you have given me hope. So thank you 🙏 I commend you heartily
I appreciate that@@Nushqa . Took me 6 months to pluck up the courage to give it a go. I have so much to learn but feel ready to take this on at this stage in my journey. Especially the difference in dipping versus brush on glazing time it takes LOL
Love the campfire, Floating chrome, floating iron,gold, misty forest,floating rutile.
I'm loving so many of them, now my dilemma is which to make in a bigger qty lol. I need more space!
@@FarForestCeramicsI would pick your top 5 and start with those in bigger quantities😊
Thank you for sharing your making glazes experience. I hope you make some of own creations. Looking forward to following your progress. All your videos are great to watch. Thanks again. Best of luck to you
I'm glad youve enjoyed following the journey with me, appreciate the feedback. Looking forwards to trying some pieces and scaling up the glazes, but not got anything bisqued realy to try, so need to get back on the wheel LOL. Need to make more testiles too as would love to try some layerings on these too :)
Jeanatte, thank you for sharing your process and your results! I noticed in an earlier video that you were dunking the entire tile for the entire 3 seconds. Have you considered doing graduated dunks? I've seen some people do a full dunk for one second, 2/3 in for two seconds, and the top third for one more second, to give an idea of the variance with different thicknesses. As for the hydrometer, you don't need one. All you need is something that measures 50 or 100 cc's and a scale. 100 cc of water weighs 100 grams. If 100 cc of your glaze weighs 140 grams, the specific gravity is 1.40. On the transparent, you can try adding graduating amounts of various colorants or stains (a line blend), as well as layering over other glazes. The oil spot may need to be over another glaze. And the snowflake crackle has to be very thick to get the crackle effect. From experience, it doesn't like very dark clays, although I may have applied it too think on the brown clay I tried it on.
Again, thank you for sharing your tests! Great job.
Good advice on the specific gravity. It’s really very easy to measure. I use a 100ml graduated measuring cylinder that I got on Amazon (I think they’re used in brewing so quite easy to find). Or you could get a 100ml syringe, that would work too. As for the snowflake crackle, my nerdy hunch would be that it might work better on a different clay. I’ve tested the Millenium White that Jeanette uses and it has a very high COE (basically, how much it expands and contracts, nothing to do with shrinkage), meaning that clays are less likely to craze on it. (The ‘crackle’ effect is basically a lot of crazing!)
Love that idea! Like putting an extra coat on the top!!
Wow some brilliant advice and tips there, THANKYOU!!! Graduated dunking sounds a very smart idea!.
I feel I need to re-read all the glaze notes too on each glaze as I'm sure I've missed some points he made. Just so much info at the beginning to tale in.?
Some great tips, thankyou! I never considered different results with different clays. Duh!!! Thanks so much.
Me too!
wow..i luvv the results,,,specially the floating ones....
They are super special aren't they, my favourites too.
Thanks so much, I have to agree, the floating ones are my favourites too :)
17:05 I'd Love to see this Dark Navy with a layer on that previous white, rimmed with any other color option on the planet lol
Definately would like to have a go at some layering next. Although I anticipate it's not going to be as easy as layering with commercial Brush on glazes. Lol
7:20 . I went to glazy and the description says "Over black slip, with Floating Blue added above the dots" The color of the slip is changing the glaze. Yours is on white stoneware. If you try a black clay it will look different. I'm trying that chrome glaze so pretty. Great results. That gold may be firing issue not the glaze recipe but I don't know for sure. I'm still learning as well. Thank you for sharing. 14:35 this is the glaze base recipe without colorants the blue is "0.1% cobalt and 0.25% copper" according to glazy if you look at the caption on the picture. So if you add so cobalt and copper to that glaze you will have color. The zinc oxide is for the crystal formation which causes the glaze to run. I hope that helps. I love crystals on glazes so I'm been studying them.
So much helpful advice here, thankyou so much! I feel I need to re-read these glazy sheets with more detail as I don't recall seeing all those notes which make sense what you are saying. There was so much to take in initially I think my brain went into overload. I dont have a black clay but was considering trying some black slip over the white millennium. Do you think that could work? I'm now understanding what you are saying about the base recipe and need to add colourants. Ahh makes so much more sense LOL I feel pretty stupid LOL. I do love crystals in glazes too so don't want to give up on this one for sure! The gold was impressive but something is not right, need to look into that further for sure. Thanks so much for all the advice, apologies for the delay in replying, only just back home from a few work trips, desperate to get back into the studio :)
@@FarForestCeramics Please don't feel stupid. We are all learning and this is a part of it. I've definitely made mistakes or misunderstood things. It's a part of the learning process. Your results were wonderful and very helpful to me and others. So thank you for sharing your process.
@@katlady5000 I appreciate that thankyou. It's the kindness from fellow potters that has been the biggest surprise in the whole journey, a really kind, supportive community. Love it!
@@FarForestCeramics I have found that also with my fellow potters. I have learned a lot over the years from other potters.
About the black slip, Old forge put the recipe on his blog:
'The colours I use oxides for are blue slip (0.25-0.5% Cobalt Oxide) and black slip (1% Red Iron Oxide, 1% Manganese Dioxide, 0.25-1% Chrome, 0.25-1% Cobalt Oxide).'
Most of Joe's test tiles are on black slip. There is cobalt in that slip so when he applies a runny, transparent glaze it often picks up that cobalt and turns blue.
If you scroll a bit further in Glazy you can also see his tests on white stoneware and/or on porcelain.
Also, photos often change the color and a printer does too.
Chromium oxide = chrome oxide for potters
The snowflake crackle needs to be applied super super thick and is thus not suitable for vertical surfaces. Check his photo, it is on a small plate. I find those snowflake crackles super tricky. I apply a thick, thick layer and it still seems to be too thin 😂
So helpful Ann thankyou. I could see he has the glaze on black slip but I didn't see his tests on white Stoneware. I need to scroll further. Thankyou!
All your feedback making sense. I'm not loving the crackle and applying it just to a horizontal surface is limiting I guess. I may just leave that one until I've had more experience and want to give it another try. Thanks for all the tips
Me again 😂 re the floating pink, I’m pretty sure the problem would have been the measurement of 0.01 grams for your test batch - almost impossible to be that accurate at that level! Looks very much to me like there’s just a *teeny* bit too much chromium in your batch (it takes so little to make that deep purple/pink colour) x
That's is making total sense now you say it. Measuring 0.01g was almost impossible lol.
I've been thinking about this- is it soluble? what about putting 0.1g/a multiple of that (whatever is easiest to weigh truly accurately) into 50ml (or 0.2g into 100ml) of distilled water and then adding 5ml of that mix to the glaze? would that work, I wonder? I really do not know...@@FarForestCeramics
It’s not soluble but if you can mix it up well to be fairly evenly dispersed then this is a good way of more accurately measuring out those tiny quantities needed for test batches, yes 😊
Great idea@@ibs102 , understanding your logic. I didn't use distilled water, so that's something I think I need to do with my next batch!
@@kirstinh3650 I'll give this approach a shot, thanks. Makes more sense. So hard to weigh such minuscule amount. Wondering if I need separate scales for these minute values, if that would help?
Hello Jeanette, are these glazes food safe?
Very good question. I'm pretty sure I read on the glaze notes that most were food safe. Good point. I need to re-read each of the notes and add this to my pots of test glaze so I identify any that not food safe. Thanks for the prompt.
That was a great video! There are several glazes I’m going to have to try now. I’m curious how you put your test tiles on the bases so they stay until you want them off. Do you ever use a dark clay? If you do, it would be wonderful to see the tests on it if you have glaze left. I use graduated cylinders to check specific gravity, too - really easy. Again, great video!
Hi, In the playlist 'Lets Make Glaze' the first video 01 covers me making the test tiles. I do this intentionally so I will snap them off later. Ive been away on a few work trips so hoping to do a video soon with the follow up of how I then convert these test tiles into flat pieces, hanging on test tile wall and stored digitally on Instagram with a search facility. Just never enough hours in the day! I don't have a dark clay that I work with yet, but I was also wondering if I should consider adding a black slip (like Joe does at Old Forge creations). He has the back of his white test tiles coated with a black slip, so he gets two test results with one dip. Clever idea I feel. However he makes his test tiles on the wheel so not sure how I would apply the black slip when I'm hand building lol!
@@FarForestCeramics Thanks for your answer! I’ll check that video.
