clay: metallic sharpie as glaze resist on bisque ware

Clay Body: Laguna Speckled Buff

Glaze: Clay Life's Majolica (White Gloss)

Method/Firing: Hand built slab/Cone 6; Sharpie gold metallic and ruler for resist

I'd had 3 bags of Speckled Buff, which I'm either hand building or throwing little bowls (as I can't yet lift the clay to go taller), and frustrated one day with throwing, I slab built these mugs.

I couldn't find any washi tape for resist, but I'd been watching Facebook reels of potters using the Sharpie gold metallic as a resist. 

  

I found using the Sharpie kind of difficult with the clean-up of excess glaze and too lazy to use the cotton swab tips. I decided to go with it.

Where did this aqua tint come from? Was it the outgassing of the ink from the Sharpies doing some weird chemical reaction? Or proximity to a pot glazed with Teal Appeal?

 

Hot from the kiln yesterday, I decided that I like it. I Google researched this technique, and the green marks are from the copper in the gold metallic Sharpie. So interesting. I found the washi tape I'd bought at the Japanese dollar store, and so that's the method I'll use next time for these kinds of slab mugs. However, I also just bought a forestland tree stencil, wanting to use it in some way on a mug for a mountain cabin, so that's maybe next for clay resist technique unless I return it and try something else.
