BlackDogPottery Posted October 24, 2017 Report Share Posted October 24, 2017 Hi. I was doing some research for trying to make this kind of muddy yellow color and found a few recipes that use rutile. I have some powdered rutile light that I was thinking of using. Any recommendations on how to much to add to a clear for starters? I've never used it before so does it make glazes runnier or anything like that? I was thinking 5% first. Thanks Link to comment Share on other sites More sharing options...
Mark C. Posted October 24, 2017 Report Share Posted October 24, 2017 rutile will make your glaze runny at least at cone 10 but I bet your are at cone 5? 3-5% is a good start-I would run several tests first on this There is a article on rutile glazes in October CM (ceramics monthly) some at cone 10 a base glaze at cone 5 Cone 5 is not my area of knowledge -but Rutile is since I have it made but the ton for me in my own glaze formula from laguna clay every 5 years for a about 30 years now.

Thanks. Yes, cone 6. I'll have to look it up. Have you had much luck making yellows? Link to comment Share on other sites More sharing options...
neilestrick Posted October 24, 2017 Report Share Posted October 24, 2017 Whether or not it will go yellow depends on the base glaze formula. Test, test, test.... Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted October 24, 2017 Report Share Posted October 24, 2017 Could always add some yellow ochre to tint it yellow. Small % increments. Or stains. But I find yellow ochre gives a nice muddy yellow color. Link to comment Share on other sites More sharing options...
Tyler Miller Posted October 24, 2017 Report Share Posted October 24, 2017 I feel I should add, rutile makes a runny glaze in reduction, but is refractory in oxidation. increased iron content causes fluxing. Yellowing with rutile is a function of that same iron content--in oxidation. Link to comment Share on other sites More sharing options...
C.Banks Posted October 24, 2017 Report Share Posted October 24, 2017 Small amounts of iron will help. If I remember correctly i've tried 0.5 - 2% black iron oxide with rutile/titanium with some success. Titanium promotes crystal growth so rates of cooling will affect the results more than most. *iirc titanium acts as crystal 'seeds' but others will know better Link to comment Share on other sites More sharing options...
Marcia Selsor Posted October 24, 2017 Report Share Posted October 24, 2017 Rutile works well in these glazes ^6 and these glazes do not run at ^6 if applied at the right consistency. You may need to bump up the percentages of colorants for Oxidation and also the atmosphere will change the color result. So test.

Mark C. Posted October 24, 2017 Report Share Posted October 24, 2017 It will turn yellow in cooler oxidized areas in my reduction kiln. Its a color I'm not trying to get. Link to comment Share on other sites More sharing options...

Pres Posted October 25, 2017 Report Share Posted October 25, 2017 I like to add rutile to a lot of my glazes, just something that it does to the surface, the crystal growth, and the durability of most glazes. I usually start with at least 4% and work upward. Nice with tin oxide. I use a base glaze using Zircopax, Rutile and tin oxide. best, Pres Link to comment Share on other sites More sharing options...

BlackDogPottery Posted November 16, 2017 Author Report Share Posted November 16, 2017 Update. I added rutile to my base glaze and it didn't come out anything like I would imagine. 4.5% Rutile . A soft grey that unusually turned black manganese specks to an orange rust. Bizarre to me as I was expecting a yellow. However its pretty nice to me and cant wait to use it. https://imgur.com/leYKL0Z 4.5% Rutile : 4.5% Red Iron. Even more surprising was this odd shade of black https://imgur.com/OEQTuvv Link to comment Share on other sites More sharing options...
