This is a ceramic mug shaped like two glass fish floats with cork spacers. The mug gets its name from the Pacific Ocean current where these adrift floats often spend decades swirling around before being swept up in other ocean currents prior to washing up on shore. This mug is part of the Caliente Collection, which is produced by Eekum Bookum and in this case designed by Doug Horne. Only 30 were created in Glossy Rutile Blue and are signed by the artist on bottom and sold through his Etsy shop. Blue Rutile is an active, complex glaze that is a flowing blue where thick and breaks brown where thinner.
