Is a porcelain vase or a bronze mantel clock produced in the 1830s superior to a similar vase or clock produced 50 years earlier or 50 years later?
In most cases the answer would be yes.
As more and more decorative objects were being produced in the second half of 18th century and early 19th century, the techniques and materials used to produce those objects were slowly evolving.
But then came the first industrial revolution. Development of new machines and increased application of scientific methods helped significantly improve quality of the materials used, perfect old techniques and develop new ones.
Yet, all intricate details and finishing work were still done by hand. The quality of the finished product was still very much a matter of pride for the master craftsmen.
