Czech seed beads we buy from the PRECIOSA ORNELA factory in the Czech Republic. The history of Czech bead production goes deep into the 16th century, when the first glass furnace was lit in the North Czech town of Mčeno. However, the manufacturing roots of this unique product can be traced back to 1500 in Venice, Italy. From there it gradually moved to North Bohemia, where it was perfected and the uniquely wide range and quality of its products became internationally known.
These round-shaped seed beads are manufactured using unique technology for cutting glass tubes with round or square holes into various sized pieces which are then rounded and polished when hot and subsequently classed by size and shape.
The PRECIOSA Rocailles are produced in sizes from 1.5 mm to 8 mm and the sizes of the Czech PRECIOSA seed beads are stated using the traditional so-called zero series. The regular sizes range from the smallest 16/0 through to the largest 1/0, while rarities also include the four large sizes of 31, 32, 33 and 34, known colloquially as potatoes.
We divide the PRECIOSA Rocailles into so-called uncoated and coated rocailles according to the level of their subsequent finish. Whereas uncoated rocailles are left with the pure glass finish, a coated rocaille is given a further surface finish, for example colouring, galvanising or other types of decoration.
Czech seed beads have the PRECIOSA Traditional Czech Beads™ brand, with which PRECIOSA ORNELA guarantees the best quality and the widest range of colors, shapes and sizes. 150,000 shapes and sizes, in 16,460 colors.
