This bowl is called the "Tiki Mug Vulcano" in the APS catalogue and "21oz Volcano Tiki Mug" on the U.K distributor's website. (Don't ask me why - it's clearly a bowl rather than a mug!) It's designed and manufactured by APS Glass & Bar Supply in Germany. Matte brown glaze on the outside and the three tikis with a lava red glossy glaze on the interior and spilling out over the edges. Marked "APS Tiki" on the base. 95mm high and with a diameter of 200mm... according to the website I got it off.
