So, I have taken a vacation from blogging for a while since I began the sink project months ago and I can finally reveal the results!
I waited ages for it to dry slowly to leather hard and I gently trimmed a simple foot for it and disengaged it from the plastic bat. I was leery of inverting it and supporting the weight of it by the rim so I did not carve out a nice ring foot even though there was like 1cm of material to work with. Because of this, the pot is substantially heavy. On the other hand, it's a sink so its stability is actually a good thing.
Then after it was bone dry, (again ages later) I gently brought it down to paint it with sapphire blue terra sigilatta. After letting that dry, it was fired and the glazing began. I started out with a base of Blue Satin glaze which created the yellow/mocha background and provides a seal over the whole piece as well as a hint of mottling. I poured the glaze over and in to the vessel since it was way way too large to dip. I then added chrome green, green mottled, light blue mottled, and finally ultramarine blue drips from the rim on the inside and out. After each drizzle stage I stepped back the glaze with a green abrasive pad so that the glaze would not get too thick and mar the coat. It was really important to me for this project to have a complete inner seal.
On the outside, the glaze disengaged in places leaving a dark greenish blue burnished texture that is really interesting.
The mounting plan is a simple one... A pop up drain with a wall mounted faucet. I have contacted my architect Chris about designing an infinity drain so that if the sink overflows, it will run down the edge and be caught by an external drain channel that is hidden by river rock. It's just a thought but I saw his design and it looks supercool.
