still-sound 30. Lava
I've been wanting to get the porous lava surface on some vases for a while now. I learned that the addition of silicon carbide to most glaze mixtures will cause the effect. I added a spoonful of the powder to a yoghurt-pot amount of glaze and brushed the mixture on to the bisqueware while it spun on the wheel. I was nervous that the surfaces would explode a bit in the kiln, ruining my fellow potters' work. I decided that the risk was slim so I had them fired. Thankfully there were no explosions.
I collected the two larger pieces today. A smaller pot was ready before Christmas. I got a bunch of freesia for it so that the apartment would have that sweet, floral bubble-gum scent through the holidays. I'm going to give the freesia pot to Francine when I next see her, the cool woman who gave me pure essential oil of the Sultan of Brunei ta'if rose.
