This group contains a mug, an 18 oz. jug, and a porringer; all in a beautiful black glaze.  The glaze is period correct.  (I own a couple of 18th century ceramic pieces that are glossy black.)

These are made of stoneware and are very durable.   They are food, dishwasher and oven safe.  

Sold separately they are $75 .   Bought as a group you get a 25% savings.
