Croatia and Slavonia were declared appanages of the Hungarian crown - pastes adnexae, or subject provinces, according to the Magyars; regna socia, or allied kingdoms, according to their own view.
The process was known at an early period, and was employed for the purpose of subsidiary decoration from the close of the 16th century, but not until the 19th century did Japanese experts begin to manufacture the objects known in Europe as enamels; that is to say, vases, plaques, censers, bowls, and so forth, having their surface covered with vitrified pastes applied either in the chain plev or the cloisonn style.
It is plain that such a method as the latter implies great command of colored pastes, and, indeed, no feature of the manufacture is more conspicuous than the progress made during the period1880-1900in compounding and firing vitrifiable enamels.
Among the city's manufactories are breweries, iron and brass foundries, stove factories, knitting mills, cotton mills, clothing factories, slaughtering and meat-packing establishments, cigar and cigarette factories, and manufactories of adhesive pastes, court plaster, spring beds, ribbed underwear, aniline dyes, chemicals, gas meters, fire-brick, and glazed paper and cardboard.
By the ancient Greeks and Romans obsidian was worked as a gem-stone; and in consequence of its having been often imitated in glass there arose among collectors of gems in the 18th century the practice of calling all antique pastes "obsidians."
