Hi, I know that this is Jasperware by Wedgewood and I found this description online:

Wedgwood Blue Jasperware Pitchers

Jasperware, or jasper ware, is a sort of pottery very first established by Josiah Wedgwood in the 1770s. Typically referred to as stoneware, some authorities have actually explained it as a sort of porcelain. It is noted for its matte surface and is produced in a number of different shades, of which the most effective known is a pale blue that has ended up being understood as Wedgwood Blue. While called after the mineral jasper, modern analyses suggest that barium sulphate is an essential active ingredient.

I found one for sale for $49.99 on thewedgewood.com
