In the history of Royal Crown Derby, from 1811 to 1848, Robert Bloor took over the company. At first he used the old marks; however, c.1820 he began to use the Bloor Derby mark we find on this fine waste bowl This mark is referred to as a red mark, but, as you can see, on this and other pieces, the mark is more orange than red. The bowl is in beautiful condition. It has a gilded garland around the upper perimeter enhances by hand painted and enameled blue designs. thin band of gilding encircle the top rim and the foot on the bowl. It is 6.25 inches in diameter and just over 3 inches tall.
