Glass Pressed Beads are one of the oldest types of beads. They are the
embodiment of boundless human imagination in one of the most beautiful
natural materials, traditional Bohemian glass. These were the first
beads that were made here over three hundred years ago using the
technique of pressing heated glass rods in a mould.
These Czech pressed glass beads have a uniform round lentil shape and their large hole size to bead size ratio makes them ideal for consistent bead weaving texture and multiple passes of fine beading thread.
Coating with luster: Luster is an organometallic compound. Luster is applied to the substrate by painting, spraying or dipping. After loading, the luster is fired at temperatures of 500 - 650 ° C. Firing temperature depends on the kind of luster. Colour luster usually fired at lower temperatures (500-570 ° C), "metallic" luster (gold, platinum, bronze) require higher firing temperature (570-650 ° C). When firing leads to burning of organic components luster; metal component is oxidized with atmospheric oxygen on the respective metal oxide. After firing the substrate remains on the surface of the metal oxide thin film whose adhesion to the substrate, the color and overall looks can be affected by the chemical composition of the substrate.
