The stain is Mason 6020. The porcelain body is L3778D1 (covered with a transparent glaze). Manganese alumina stains are highly refractory, so much so that they simply do not work in glazes. But in vitreous bodies, like this one, the stain has no effect on the degree of vitrification! And produces a vibrant color - one that is difficult to achieve in glazes.
This is L4588 red burning porcelain. I got the idea after coffee break and was rolling and pressing specimens right after lunch.
10.30 am: I got the idea to make this, created a record in my Insight-live account, code-numbered it and printed the recipe.
10.35 am: I started weighing it out.
10.40 am: I blender mixed it really well to remove all agglomerates.
10.45 am: I poured it onto my plaster bat.
12.30 pm: It had stiffened to the perfect consistency to roll a couple of SHAB test bars and press and stamp some porcelain theme rocks.
Next day: In the kiln. Next day: Incredible red porcelain at cone 6.
Much of the reason not to be intimidated by mixing tests like this is having all the tools and materials close at hand and a good record-keeping system. And making sure to enter results, notes and pictures as tests are completed. And linking this to related tests (I am also working on a pink and a blue).
