Bow paste is exceedingly hard, and the fracture when it is broken is close and compact. The pieces as a rule are very heavy for their size, but many of the cups and saucers are almost of egg-shell thinness. The colour is milky white. Should any of our readers be possessed of Bow china, they may ratify its origin by carefully examining it, if possible, under a magnifying glass. On scrutinising the blue pieces it will be found there is a peculiarity in the glaze, which arises in this manner. At that time blue was the only known colour that would bear the intense heat of the kiln. It was always painted on the biscuit before being dipped in the glaze. It is found that certain portions of the blue, however slight, are apt, while the glaze is in a fluid state, to spread over the surface, giving it a blue tinge. The other colours as well as the gold were painted over the glaze, and set in a kiln of lower temperature. Hence the blue, being _under the glaze_, is imperishable, and the other colours from frequent use get rubbed off. We have given a number of marks used at Bow; we supplement that list by two others, one of which is exclusively composed of signatures actually used by Thomas Frye himself. Although none of the ware unearthed at Bow was printed, yet printed ware did come from there. In all probability it was sent to Liverpool to have the transfer engravings, so much in vogue when Bow flourished, put on the china. As early as the year 1756 this was done, for certain entries appear in the Bow books: “One pint _printed_ mug: a sett compleat of the second _printed_ teas.” Or it is possible that they were sent to Battersea to be printed. It is not a far cry from Bow to Battersea. Transfer printing on enamel was in vogue at Battersea before 1755. Horace Walpole, writing to a friend in 1755, says, “I send you a trifling snuff-box, only as a sample of the new manufacture at Battersea, which is done with copper-plates.” But Battersea and Battersea enamel—that is another story.
