Gorgeous Iron Oxides
Just look at those colors! The Crocus Martis is an iron oxide. In the chemical state it has a rich raspberry hue. The Spanish RIO is more orange and reminds me of terracotta. I mixed up a few cone 6 iron recipes, plus a few with revisions. To get the nice rusty orange/red results in oxidation, a slow cool is suggested. I decided not to program a custom cool down because my kiln is pretty big and it cools slow naturally. Also I didn't want to chance messing up my other glazes. If the reds don't happen in my current firing schedule, I might try a programmed slow cool at a later time. I would really love to have a small programmable kiln for testing and small loads. I checked out a new little L&L and about fell off my chair when I saw the price. I'll just keep watching craigslist.
Labeled and ready to dip. I only have one Mason Stain in this test run. I'm more curious about arriving at colors with oxides and other chemicals. I love being surprised.
There is just something really beautiful about test tiles.
Firing today. Hope these tiles will result in some glazes worth keeping.
