elainecarroll Posted November 5, 2012 Report Share Posted November 5, 2012 I am very new to making glazes and would really appreciate some help. I am looking for some matte glaze recipes that would allow red iron oxide to show through. If anyone can point me in the right direction, I surely would appreciate it. Thanks Elaine Link to comment Share on other sites More sharing options...

neilestrick Posted November 6, 2012 Report Share Posted November 6, 2012 To get iron to show through in cone 6 oxidation, it takes a lot more iron than in reduction. I used to use a 10% iron slip in reduction, but use 20% iron in oxidation. Whether you're using a slip or straight iron oxide, it will show through most matte glazes if the iron/slip is thick enough. Glazes that are matte due due crystal growth rather than due to under-firing will tend to show it more because it will get into the melt more. Test, test, test....

Thanks so much, that is exactly the info I needed. I will start testing. Link to comment Share on other sites More sharing options...
