Saving A Bowl Using Black Iron Oxide

Описание: This method doesn’t work all the time, and I should reiterate this, if you’re trying this in oxidation you WILL get different results, as iron in reduction acts completely differently. The effect is completely different on this mossy green glaze for instance, it flows much more, whereas on the more crackled, feldspathic glazes I’ve previously done this on it clings to the surface much more as it melts in the second firing, creating an entirely different look that I prefer in all honesty.

I don’t add anything special to the black iron oxide, I simply water it down until it’s a thickish slurry, you don’t want it to be too wet or it really won’t cling to the surface of the fired pot you’re brushing it on. Equally, when applied too thickly it just flakes off as it dries, meaning there’s a bit of a knack to getting it right and it’s one you’ll have to figure out on your own. Additionally, if you’re trying this in reduction, please be wary about how it’s applied to outside of your pots as it runs like water, I stuck a few pots my kiln shelves by being overly ambitious, now if I do want to coat the outside of the vessel I only brush the BIO around the rim, or I just use red iron oxide instead, as it’s ground more coarsely and doesn’t seem to flux and melt nearly so much.

I’ll hang onto this little bowl for now. It’s a test really and I’m not entirely sure I like where you can see the scratch marks underneath the watery layer of glaze on the outside, that’s the one downside with this particular glaze, whereas those I’m used to working with just hide everything that’s beneath them.
