No this mug is one of possibly five early test glaze test pieces, Holden sent me the pictures and I noted that it had too many teeth, a solid run of teeth and not peg toothed like the production drawings. So the factory re-tooled the master and the regular peg-toothed Mana Mana went into production.
So this mug is 1 of 1 for this glaze and teeth. If the Mana Mana is successful to make it to a third glaze variation then I'll defiantly suggest this white/orange glaze as it brings out the detail.
I checked with the tutor at my ceramics class and she said that she'd had a ceramics piece that had "Plinked" for three months after firing. She also confirmed it was likely to be glaze and not as I suggested, Haunted.
