Brandon Franks Posted July 12, 2019 Report Share Posted July 12, 2019 Hey all, I heard about people adding RIO to clay a long time ago. I was wondering what percentages of RIO do to the clay. I was thinking about mixing it into some pugged clay to get a more consistent color. Are there any recommendations/concerns that I have to be aware of. The clay that's pugged is like four different clay bodies and is brownish when fired. It's probably around 35% Standard 211 making it brownish, but has other whiter bodies in it making it a bit lighter. I just want to get more consistent color throughout it. Any tips or articles I can read? Thanks, Brandon Link to comment Share on other sites More sharing options...
neilestrick Posted July 12, 2019 Report Share Posted July 12, 2019 Adding RIO is not the best way to add iron to a clay body. You'd be better off adding a high iron clay. Adding either can/will affect the firing temp, though, so you'll need to do some testing. Link to comment Share on other sites More sharing options...
This is it Posted November 7, 2020 Report Share Posted November 7, 2020 What is the color of the mix when it is finished? Is it a copper color? Link to comment Share on other sites More sharing options...
oldlady Posted November 8, 2020 Report Share Posted November 8, 2020 when i did some standard 112 clay birdbaths, i added spanish red iron oxide to a few pounds that i used as accents. the color was red brown, not copper. Link to comment Share on other sites More sharing options...
