A friend from Switzerland gave me a glaze recipe that calls for rutile
granular. I've not been able to locate a place locally where I can get
it. Can rutile be substituted for rutile granular?

DJ - The recipe has 4 parts rutile in the base and 4 parts granular rutile
as added colorant (which you would add after glaze has been wet sieved).
The granular rutile is for color/texture/spotting/streaking/etc. In the
glaze.
Axner has granular rutile:

No. Granular rutile makes dark speckled marks; powdered
rutile is a colorant in the yellow-brown range. They are not
interchangeable at all. Most suppliers do sell granular rutile,
and since a little goes a long way, it might be worth doing
mail-order. If you'd really rather not,though, I'd use granular
manganese instead, which makes similar dark specks.

My experience with the different rutiles is that=3D20
the difference in result is often more in texture=3D20
than in color. Those with more iron will be
a bit darker in result as well as in appearance,
but appearance and result the fineness of the
milling is critical.
Rutile comes in different grades, there must be
a dozen at least, and the stuff that you buy=3D20
that's just called "rutile" can be any of them.
In short, I'd give the recipe a try, just to see.
It does have quite a bit of titanium in it, and
you may need far less to get a yellow glaze.
I have no idea what the consequence of that much
titanium is, but I'd suspect that won't come
close to being dissolved in the melt.
Are you sure the recipe you got is right? It
shows rutile separately from granular rutile,
but calls for essentially the same amount of
each.

No, I used both, in 2 glazes :

No. THe granular rutile makes spots, the regular rutile makes an
allover color. By the way, you're getting titanium in the rutile and
titanium in the granular rutile (although that probably isn't entering
into the overall glaze chemistry much, plus 16% titanium dioxide
added. That's a HUGE amount of titanium. It's really likely to make
this glaze very refractory. I'd bet you could cut that added TiO2 in
half and not notice any difference.

Hi DJ,
I get a total of 99.9 - it calculates high in both alumina and silica
for a cone 6 glaze and is very high in TiO2 - makes me think it may
not be melted enough to be stable.
Granular rutile is usually used to give some specking and does not
enter into the melt. I'm fairly sure you will find some granular
rutile around - I have lots if all else fails.

If I got a recipe from Switzerland that called for "rutile granular",
I wouldn't spend money on buying a shipping a little bit of a
rarely used ingredient, and would simply go for my jar of
the much-more-common granular illmenite.
I know, on paper there is more iron and less titanium in illmenite,
compared to rutile, but they are really similar and both would
give the same spotted effect. In a recipe that already has 16%
titanium I certainly worry about not having enough.
Heck, it may just be a case of poor translation, and granular
illmenite is what they meant to begin with.

The recipe my friend from Switzerland sent me of Deep Yellow is from
Ababi Sharon from the clayart archives.
http://www.potters.org/subject53503.htm/
In his post, he mentioned that the 16 titanium was a mistake from a
long day of glaze making. He said that it could be made with 8 titanium,
and that if one did not have any granular rutile, to bump the amount of
rutile up to 8. I decided I was going to try using ilmenite for the
specks, once I finished reading about rutile in all its forms on Digital
Fire.
Thanks very much for your response. Many people have been very kind in
imparting detailed information to me on this topic. I'm very grateful.
I got many personal responses in my inbox, and sent back thanks to the
wonderful souls who helped with valuable information.
I'll post photos and the exact recipe I use once I get it mixed and fired.
much love
DJ
