A beginning was made, and the tin-plates manufactured by Yarranton's men were pronounced of better quality even than those made in Saxony.

"Many thousand plates," Yarranton says, "were made from iron raised in the Forest of Dean, and were tinned over with Cornish tin; and the plates proved far better than the German ones, by reason of the toughness and flexibleness of our forest iron.

One Mr.Bison, a tinman in Worcester, Mr.Lydiate near Fleet Bridge, and Mr.Harrison near the King's Bench, have wrought many, and know their goodness." As Yarranton's account was written and published during the lifetime of the parties, there is no reason to doubt the accuracy of his statement.
Arrangements were made to carry on the manufacture upon a large scale; but the secret having got wind, a patent was taken out, or "trumpt up" as Yarranton calls it, for the manufacture, "the patentee being countenanced by some persons of quality," and Yarranton was precluded from carrying his operations further.

It is not improbable that the patentee in question was William Chamberlaine, Dud Dudley's quondam partner in the iron manufacture.[15] "What with the patent being in our way," says Yarranton, "and the richest of our partners being afraid to offend great men in power, who had their eye upon us, it caused the thing to cool, and the making of the tin-plates was neither proceeded in by us, nor possibly could be by him that had the patent; because neither he that hath the patent, nor those that have countenanced him, can make one plate fit for use." Yarranton's labours were thus lost to the English public for a time; and we continued to import all our tin-plates from Germany until about sixty years later, when a tin-plate manufactory was established by Capel Hanbury at Pontypool in Monmouthshire, where it has since continued to be successfully carried on.
We can only briefly refer to the subsequent history of Andrew Yarranton.

Shortly after his journey into Saxony, he proceeded to Holland to examine the inland navigations of the Dutch, to inspect their linen and other manufactures, and to inquire into the causes of the then extraordinary prosperity of that country compared with England.
