About Czech Glass Beads

Czech Glass Beaded Earrings
By DJAjewels on Etsy


I use a lot of Czech glass beads in my jewelry designs - like the one pictured here.  So I decided to learn a bit more about these beautiful beads.

Czech glass beads are, of course, made in the Czech Republic.  Sometimes we hear these beads referred to as Bohemian glass since this area used to be called Bohemia.  During the 1800's, the Bohemian and Venice glass makers competed intensely against each other for the glass market.  Industrialization, however, during the 19th century brought about major changes in the way Bohemian glass makers produced their glass.  During this time, Venice continued to produce handmade glass beads, while the Czechs perfected the art of mass producing them using machines.  These machines pressed molten glass into heated molds producing many glass beads at once instead of one at a time.

World Wars I and II nearly caused a collapse in the Czech bead industry but it survived and was even thriving again by the 20th century.  Today the Czech Republic dominates the mass production of glass bead making, and they are known for their highly consistent quality and wide array of finishes.  Some of these finishes include:

Aurora borealis (AB):  An iridescent somewhat metallic finish with a highly reflective quality.  The beautiful shimmer of these beads is obtained by applying the finish to only some areas of the bead.

Fire-polished:  Faceted beads polished by tumbling them in a heated container.  This process adds sparkle to the facets.

Crackle:  These beads have a crackle appearance obtained by heating the glass until it cracks and then re-heating it enough to create a smooth finish on the surface.  The crackles are then visible beneath the surface.

Matte:  Non-shiny appearing beads.  These beads have a softer look than the shimmering AB beads.  Other names include Satin and Frosted finishes.

Vitrial:  Reflective glass beads with a silver colored coating applied to a portion of the bead's surface.

The many colors, finishes and shapes of Czech glass beads available today allows jewelry designers to create unique, interesting and even one of a kind designs!

My Newest Beading Addiction: Czech Glass Beads

I have been busy this week beading several new pairs of vintage style earrings after finding some really interesting and pretty Czech glass beads.  These beads can be addictive to work with because of the incredible assortment of styles, colors and finishes available.  I order my beads from various vendors and I really never know for sure whether I'm going to like the beads until they arrive - but every single one of these beads turned out to be spectacular and I could not wait to start beading with them.

Temptation Glass Garnet Earrings:  These glass garnets are simply too tempting to resist!  I beaded these earrings with deep garnet Czech glass beads dangling from antiqued brass chain and earring wires.  Accented with antiqued gold Heishi beads and bead caps.  Faceted rondelle Czech beads are 14mm size.  Drop is 2 inches.


Picasso Purple Amethyst Earrings:  These vintage style earrings are prettily beaded in purple and sterling silver,  Faceted Czech glass rondelle beads are an eclectic combination of pinks, purples and white.  They have a picasso finish giving them a beautiful marbled stone appearance.  The faceted edges allow the light to dance and reflect off of them - they measure 9x6mm.  Round amethyst gemstone beads sit atop the Czech glass rondelles and small amethyst Swarovski crystals dangle beneath them.  Accented with antiqued silver Heishi beads and bead caps.  Bright sterling silver kidney shaped earring wires.  Drop is 2 inches.

Celestial Blue Vintage Style Earrings:  I beaded these Celestial Blue dangle earrings using pretty blue Czech gire polished rondelle beads.  These faceted opaque beads are a soft tranquil light blue - but their faceted edges contrast beautifully with the soft color as they allow the light to reflect and dance off of them.  Small round cloud white Cats Eye beads add to the celestial appearance.  To give these earrings a Victorian and vintage style appeal, I used oxidized antiqued sterling silver earring wires along with antiqued silver plated Heishi beads and bead caps.  Gunmetal eye pins and jump rings complete the vintage style charm.  Drop is 2 inches.  Blue rondelle glass beads measure 9x6mm.  Cats eye beads are 4mm.

Glass garnet rondelle, Picasso purple, and celestial blue czech beads are all from ShipwreckBeads.

Bead Facts About Swarovski Crystals, Czech Glass and Lampwork Beads


Ever wonder what the actual difference is between crystal and glass beads? And what exactly are lampwork beads? Well each bead has its own unique qualities and characteristics. While Swarovski is considered the "gold standard" in the crystal industry, Czech glass beads offer an affordable yet beautiful alternative. And lampwork beads can have such incredible depth and intricate designs not found in other types of beads!
The following article offers a summarized description of all these bead types.
SWAROVSKI CRYSTALS:
About Swarovski crystals: Swarovski crystals are considered to be the finest quality crystal bead made today. They are known for their flawless consistency, brilliant colors, and dazzling ability to reflect light. Swarovski is extremely secretive about their manufacturing process, and while there are other companies that manufacture crystal beads, Swarovski is the industry leader and maintains the standard to which all other companies strive to achieve. Each crystal is faceted with tremendous precision resulting in an optically pure product. Swarovski® uses cutting and polishing techniques that are superior to any other and they, therefore continue to dominate the crystal market in their creation of truly stunning and spectacular crystal beads. Some of the most popular crystals are finished with an aurora borealis (AB) finish which produces a brilliant iridescent effect.
What about lead? Do Swarovski crystals contain lead? Yes, Swarovski crystal is an Austrian lead crystal which usually contains about 32% lead. Is this a health hazard? Not likely unless the crystal is ingested. General handling and skin contact is not thought to pose any significant health hazard because of the special manufacturing process which reduces the ability of transferring lead from the crystal to skin surfaces. This is different from non-plated metals containing lead that are more easily transferable to skin surfaces.
Swarovski crystal pearls: Swarovski crystal pearls are made with the same precision as Swarovski crystal beads. They are called crystal pearls because they are created around a core of an actual leaded crystal bead making them heavier than the more common synthetic glass pearls. The outer portion of the pearl is finished with layers of pearlescent “nacre” which very closely resembles a natural pearl, and they warm to the skin like real pearls. Swarovski crystal pearls are also resistant to body oils, perfumes, UV rays, and scratches.

CZECH GLASS BEADS:
About Czech glass beads: Czech glass beads are available in a wide variety of finishes and styles. Some of the more popular styles include aurora borealis (AB), lampwork, matte, metallic, opaque, and transparent.
History of Czech glass beads: Czech glass beads are made in the Czech Republic. In ancient history, beginning as early as 400 A.D. these beads were made by hand by glass artisans in Bohemia (now the Czech Republic.) There was intense competition between the glass makers in Bohemia and in Venice, but during the industrialization of the 19th century, new machines were invented that could mass produce a wide array of glass beads by pressing molten glass into a heated mold. While Venice continued to concentrate on creating handmade glass beads, the Czechs perfected the art of mass producing pressed glass beads. During WWI and WWII, the bead industry nearly collapsed, but by the mid 20th century, the glass bead industry had been revived and today the Czech Republic dominates the glass bead market. The Czech Republic is now known for their ability to mass produce beautiful glass beads with many different finishes that are consistent in quality. Jewelers around the world use Czech glass beads to create beautiful necklaces, earrings and bracelets.
Czech Fire-Polished Beads: Czech fire-polished beads are sometimes called crystals but are actually classified as glass beads rather than crystal. They are made by pressing glass into a mold to make the bead and then faceting it either by hand or machine. The "fire-polish" is attained by slightly melting the surface of the bead to enhance the luster. This process results in a slightly rounding off of the facets which identify it as glass rather than crystal. These beads compete with the more expensive Swarovski crystals.
Other Types of Finishes: Aurora borealis: Often referred to as “AB” for short, this finish is iridescent and somewhat metallic. It has a colorful reflective quality that results from the finish being applied to only some areas of the bead’s surface. Other names for AB are Iris, Iridescent, and Rainbow. Crackle: Crackle beads are created by heating the glass until it cracks and then re-heating it enough to create a smooth finish on the surface. The crackles are then visible beneath the surface of the glass. Metallic: Metallic beads have a thin coating of metal applied to the surface by either painting or electroplating. They can be susceptible to scratching. Matte: Matte beads have a non-shiny appearance and texture. Other names include satin finish and frosted.  Picasso: Picasso beads have a marbled finish resembling stone.  This look is achieved by fire polishing the bead to melt the outer layer of glass followed by exposure to various gasses from gold and other metals.  The result is a unique pattern of colors and patterns. Vitrial: This reflective finish results from a silver-colored coating being applied to a portion of the bead’s surface.

LAMPWORK BEADS:
What are lampwork and Venetian beads? The terms Venetian beads,Murano glass beads and lampwork beads are often used interchangeably. Lampwork beads are created with rods and tubes of clear and colored glass which are worked over an open flame, then blown and shaped into beautiful glass treasures. Since these beads are handmade, sizes and shapes can vary slightly. Since glass artisans in Venice and Murano are known world-wide for their lampwork glass creations, lampwork beads are often referred to as Venetian glass beads or Murano glass beads. Lampwork beads, however, are created today around the world. While true Venetian or Murano glass beads only really created in Italy, there are many beautiful beads created in China. And I have found really unique and beautiful handmade lampwork beads on Etsy where there are a number of very talented glass artisans. In fact Etsy has become one of my favorite sites to find unique lampwork beads for my jewelry designs.



Types of Lampwork Beads:

Fiorato Beads: These are a variation of Murano and Venetian glass beads created using melted glass to “paint” flowers and decorations onto the surface. Foil lined: These beads contain either white gold foil, 24K gold foil, or .925 sterling silver foil submerged beneath the glass brightening the color and producing a radiant glow. Millefiori Beads: Variation of Murano and Venetian glass beads hand-created by working slices of millefiori glass canes into each bead. Millefiori means “thousand flowers” in Italian. Sommerso beads: These beads are created using a technique in which the glass artisan submerges different colors beneath clear glass. Small copper flakes (called aventurina) are then worked into the clear glass giving the bead a look of depth and a rich luster.
