54. Same Glaze Different Results

The same glaze can produce very different results. But why is that?
In this video I will explain about the most important factors that influence the results of your pottery glaze. And I will be testing three of the most popular glazes on 5 different kinds of clay.
- Floating Blue
- Folk Art Guild White
- Temmoku Gold
The 3 glazes will get some extra enhancements with Heath A2 White and my own pitfire ash glaze.

Thank you for taking all the time to produce this video - I'm sure it was a lot. I love your results and would agree with your top picks but all of them are beautiful. I also love the bowl form. Our potters guild is having a fund raiser and we need to make 500 bowls - 100% of the proceed is donated to various causes. I usually make heart shaped bowls for donation but think I'd like to make ones based on your facet bowls. I've never been really successful with faceting bowls but I'm motivated after seeing how beautiful yours are to become proficient at making them. They show the glaze so nicely, the form in interesting and stack well. I'm going to check your list of videos to see if you've featured throwing these and if you don't have one - I might not be the only one interested in seeing your process 😉. Again thank you for all your videos - such a wealth of information you have shared.

Mikkel, thanks so much for your incredibly well made videos. I just discovered your channel this morning and have watched two already. I work in a tiny cone 6 hobby studio in upstate NY with 3 others. We are not making functional work and only one person sells. We have made our own glazes but our floating blue has been a dismal failure. Is there a place where you share this recipe? Also, thanks for the amazing tip on sucking up the glaze into the inside (!) Debbie

[@deMibPottery]

Thanks a lot :-) The Floating Blue variant I most often use is close to what OldForge is doing where Menganese is used instead of RIO: glazy.org/recipes/77013 Also remember, that Floating Blue require a VERY thick layer to work well and do not work well on all clay types

[@debsamuels5367]

@@deMibPottery Thanks so much! I am going to check out both this recipe and John Britt's incredible Temmoku.

[@jasonsj]

Thank you for the nice video! Love the bowels! I just started potty and really enjoyed it and would love to make career out of it. But recently I saw lots of KZbin videos showing the profitability of their small pottery business. It is like tepid sales every month, which intimidated me from making pottery a career. So I wondered if you could please share how your journey as pottery business owner and what are the channels you usually sell your pieces, that would be very helpful and informative. Thanks a lot! 👍

[@deMibPottery]

Thanks :-) All arts- and crafts business is difficult. I used to do music production for a living. That was NOT easy either :-) I sell through my webshop, social media and a few shops and galleries. Some also do art fairs but I think that is too much work compared to the revenues from them.

[@user-ly1nm4th3e]

These are beautiful …Would love to know which floating blue recipe you use….

[@deMibPottery]

Thanks. I use a variation with manganese instead og RIO

[@donnamanley8172]

Even John Britt's cone 6 book has two different recipes both named Temmoku Gold.

[@deMibPottery]

Yes, and that is sort of odd. I use the one with 11.2% RIO

[@C-M-E]

Almost ironically, water is perhaps the most overlooked basic material when it comes to ceramics in general. Chemistry teaches you to use the most pure form out of principal for purity's sake, but on the scale of bulk materials, it's not always fiscally reasonable. On the flip side, I've gone out of my way to use distilled water trying to maintain certain ph's and limit variable chemical interaction, but some clays just want tap water or even scumish bucket water that ran off the roof at one time. I'm not geographically near salt water to try it other than adding it afterwards, but I'm rather curious if using sea water has an appreciable strength quotient/difference vs fresh water sources.

[@deMibPottery]

Unlike many countries we have very good clean tap water from the underground. We do not filter it or add any chemicals so it works well for me

[@C-M-E]

@@deMibPottery "If it ain't broke..." 👍 I've gotten some interesting ideas from your videos to try, but that temmoku is absolutely stunning. Definitely going to try to replicate it for the next go.

[@deMibPottery]

👍 I love the temmoku gold too. So vivid and variated

[@xm3364]

Hi Mikkel. Great experiment! The last set of colours came out very lovely-Like poppies! The first set of blues are very cool! Definitely will try the combination of glaze! 1 question, is there any particular sequence of layering the glazes; Tenmoku over Floating blue or Folk Art over/below Floating blue (example)? Or the more fluid glaze over/under the less runny glaze? Appreciate your kindness if you can clear my curiosity mind. :-) Many thanks!

[@deMibPottery]

Thanks a lot Very often - but not always,, the results is very different depending on the order your layer the glazes in. I haven't found any global logic to this (although there may be), so my best advise is to test it. Also keep in mind that the type and color of clay also plays a huge role.

[@xm3364]

@@deMibPottery Will definitely do testing. Seems glazes came out more interestingly in red/black clay than white. Thank you:-)

[@suzihumphries-yw3hr]

Hi there... I found this video so helpful thank you for sharing all the different glazes n layering... Could I please ask what floating blue glaze you used and also how thick you make it (S.G) ..i am never too sure how. Much water to add etc xx thank you 😉

Thanks a lot ❤️ The Floating Blue I use is variation of OldForge’s. Its capprox SG 1 .42

Are you adding some gum to the glazes or just dry ingredients and mix with water? Really cool video, thx for it!

[@deMibPottery]

I don't use any gum and such for glazes as I don't brush them on.

Hello .how do i make tamico gold.next week i starting making glazes with my teatcher and i would like to do the tamico gold.is it glaze you buy ready? Or you have your own recept?do you spend your knowledge for this glaze or it s a secret?

[@deMibPottery]

The Temmoku Gold I use I mixed myself based on a recipe from John Britt's book about mid-fire glazes. But you can also find it here: glazy.org/recipes/18336 Good luck. Its a great glaze. Especially, I think, on dark clay. The thicker the application the more fold/yellow. Thinner areas and where it breaks over edges it will be black.

[@xm3364]

Hi Mikkel. Did some testing on John Britts Tenmoku Gold (RIO 11.24%) yesterday. Fired at cone 6. And the colour is so dark and no gold specks at all. I had substituted Lithium with Spodumene. How did you achieve the surface full of golden speckles?

[@deMibPottery]

I think you need the lithium and also a pretty thick layer

[@xm3364]

@@deMibPottery Will do that. Did you schedule a slow cooling process to allow the formation of the yellow/gold crystal in Tenmoku? Mine was a regular cooling (as arranged by the studio person) Many thanks advance! :-)

[@deMibPottery]

I just use natural cooling

Hej Mikkel. Har du selv blandet din flooting blue, hvis ikke hvor er den købt

[@deMibPottery]

Ja, jeg tror ikke man kan købe den

[@user-ve3nl9lp1q]

@@deMibPottery mange tak for det hurtige svar og dine fantastiske videoer. Det måtte jeg jo erfare da jeg havde ledt nettet tyndt og kun havde fundet opskrifter. Jeg er amatør og har lige købt en ovn som kommer i næste uge, så starter eventyret med glasering. Men jeg ved ikke om jeg tør at kaste mig ud i at blande selv, eller om der er for meget at sætte sig ind i nu hvor man lige er startet, er det ikke dyrt at købe alle de nødvendige ingr. Hvor køber man dem, og kan det betale sig. Der findes mange flotte, men også dyre færdigblandede på markedet.

[@deMibPottery]

Det koster lidt at komme igang, men man kan f.eks. starte med den serie af glasuropskfter som OldForge har lavet, netop for ikke at skulle købe så meget til at starte med: www.oldforgecreations.co.uk/blog/first-five-ingredients-where-to-start-with-glaze-making Jeg køber lidt i Danmark - mest hos Silica, men mest i Hos Scarva i Irland og BSZ og Carl Jäger i Tyskland.
