This is a hand-crafted hot glass Mug. Created from the depths of the furnace with 2100 degree molten clear lava. Color has been added and textures have been formed for the right feeling. Nothing makes your beverage of choice taste as good as drinking it from this hand-blown vessel fit for royalty. This poppy red and yellow beer mug has a potted and swirled effect. The poppy red and yellow interact with each other to give it this deep burgundy effect.
