I have been working on a yellow matte glaze. One of our interns left a bucket of glaze and it looks like the glaze on the apple baker. I have been trying to repeat the glaze and the small ikebana form is as close as I have come. I know it's an iron based yellow as the glaze is red in the bucket. The intern was heading out west and I have not been able to find her. Does anyone have any idea what I could add to mine to make it more yellow? I'm thinking some rutile. Thanks for any advice.

Great on textured darker clay, lovely smooth matte white on white clay, not good on buff colors


For yellow:  add 6% rutile.  looks very much like your picture on speckled clay.  Dependable glaze, doesn't run.



It depends on your base glaze Jeff. 1-3% red iron in the right base, with a little tin (about 2%) will give a light to medium yellow. A little bit of rutile added (1-2%), may lean it toward a more warm, even peachy yellow cast.


In my Cone 6 Ox high alumina matt, at 8% rutile I get a deep, rich, orange. 6% give more of a deep peach, lighter as the rutile is lowered, so I would think 2% might give you a yellow in the right base.
