Potters & Sculptors - Making Rock from Mud
There are a number of glaze tests on my web site in the Potters Corner if anyone is interested. Many tiles are layered glazes some of which are commerical glazes I have tested plus many others. Pictures are included.
Make sure you scroll down past advertizements at top of page.
Hello Randy, I was looking at the replies and I notice the Randy Red glaze. What is RIO and is there an alternative for it since I don't have any of it???
RIO is red iron oxide- gotta have it for this glaze.
Thanks a ton, Red Iron Oxide I have. Can you send me the recipe again, I was just jumping from forum to forums and I'm not sure how to get back to where the recipe was.. Thanks
Should I come over and mix it for you, too? Just kidding, really, I couldn't help myself :)
When I fire this glaze, on the cool down I hold it for 1 hour at 1650 degrees F after slow cooling from 1900 down to 1650 @ 150 degrees per hour. Good luck.
That would be great, when are you coming??? Thanks a ton Tracy, I will let you know how it turns out. I have a firing in about a week. I will try to make you proud.....
After the hold to 1650 for an hour do you do and slow cooling? If so, can I have your firing schedule?

I'm with Randy on the hold at 1650 for an hour.
This is a red glaze I use, almost identical to "Randy's Red"- got it years
ago in school.
Gerstley Borate-28 (I still have a stash, haven't subbed yet.)
M^6 "Waterfall Brown" will also turn red if you fire this way.
