The origin of the glass is a controversial issue for the scientific community, with many evolving theories.
Meteoritic
origins for the glass were long suspected, and recent research linked the
glass
to impact features, such as
zircon
-breakdown, vaporized
quartz
and meteoritic metals, and to an
impact crater
.

Some geologists associate the glass not with impact melt ejecta, but with
radiative melting
from meteoric
large aerial bursts
. If that were the case, the glass would be analogous to
trinitite
, which is created from
sand
exposed to the
thermal radiation
of a
nuclear explosion
. The Libyan desert glass has been dated as having formed about 26 million years ago. It was
knapped
and used as a tool during the
Pleistocene
Era.

Beads
A
bead
is a small, decorative object that is formed in a variety of shapes and sizes of a material such as stone, bone, shell, glass, plastic, wood or pearl and that a small hole is drilled for
threading
or stringing. Beads range in size from under 1 millimetre (0.039 in) to over 1 centimetre (0.39 in) in diameter. A pair of beads made from
Nassarius
sea snail shells, approximately 100,000 years old, are thought to be the earliest known examples of
jewellery
/jewelry.

Beadwork
is the art or craft of making things with beads. Beads can be woven together with specialized
thread
, strung onto thread or soft, flexible
wire
, or adhered to a surface (e.g.
fabric
,
clay
).

Types of beads
Cloisonné beads
Beads may be divided into several types of overlapping categories based on different criteria such as the materials from which they are made, the process used in their manufacturing, the place or period of origin, the patterns on their surface, or their general shape. In some cases, such as
millefiori
and
cloisonné
beads, multiple categories may overlap in an interdependent fashion.They are good for craft making
Components
Beads can be made of many different materials. The earliest beads were made of a variety of natural materials which, after they were gathered, could be readily drilled and shaped. As humans became capable of obtaining and working with more difficult materials, those materials were added to the range of available substances. More recently, synthetic materials were added.
In modern manufacturing, the most common bead materials are wood,
plastic
,
glass
,
metal
, and
stone
.
Natural materials
Beads are still made from many naturally occurring materials, both organic (i.e., of
animal
- or
plant
-based origin) and inorganic (purely
mineral
origin). However, some of these materials now routinely undergo some extra processing beyond mere shaping and drilling such as color enhancement via
dyes
or irradiation.
The natural organics include
bone
,
coral
,
horn
,
ivory
,
seeds
(such as
tagua
nuts),
animal shell
, and
wood
. For most of human history
pearls
were the ultimate precious beads of natural origin because of their rarity; the modern
pearl-culturing process
has made them far more common.
Amber
and
jet
are also of natural organic origin although both are the result of partial
fossilization
.
The natural inorganics include various types of
stones
, ranging from
gemstones
to common
minerals
, and
metals
. Of the latter, only a few
precious metals
occur in pure forms, but other purified
base metals
may as well be placed in this category along with certain naturally occurring alloys such as
electrum
. There are also paper beads.
Synthetic materials
Swarovski
crystal beads (
6 mm–8 mm
), pendant 3 cm
Swedish patent 217875: The plastic bead pegboard (1962).
The oldest-surviving synthetic materials used for beadmaking have generally been
ceramics
:
pottery
and
glass
. Beads were also made from ancient alloys such as
bronze
and
brass
, but as those were more vulnerable to
oxidation
they have generally been less well-preserved at archaeological sites.
Many different subtypes of
glass
are now used for beadmaking, some of which have their own component-specific names.
Lead crystal
beads have a high percentage of
lead oxide
in the glass formula, increasing the
refractive index
. Most of the other named glass types have their formulations and patterns inseparable from the manufacturing process.
Small, colourful, fusible plastic beads (some brands are Nabbi, Hama, Perler, and Pyssla) can be placed on a solid plastic-backed peg array to form designs and then melted together with a
clothes iron
; alternatively, they can be strung into necklaces and bracelets or woven into keychains. Fusible beads come in many colors and degrees of
transparency
/
opacity
, including varieties that glow in the dark or have internal
glitter
; peg boards come in various shapes and several geometric patterns. Plastic toy beads, made by chopping plastic tubes into short pieces, were introduced in 1958 by Munkplast AB in
Munka-Ljungby
, Sweden, under the brand Nabbi. Known as
Indian beads
, they were originally sewn together to form ribbons. The pegboard for bead designs was invented in the early 1960s (patented 1962, patent granted 1967) by Gunnar Knutsson in Vällingby, Sweden, as a therapy for elderly homes; the pegboard later gained popularity as a toy for children.

The bead designs were glued to cardboard or
Masonite
boards and used as
trivets
. Later, when the beads were made of
polyethylene
, it became possible to fuse them with a flat iron. In 2005, Munkplast/Nabbi introduced the Photo Pearls software that converts digital photos to bead designs. Hama come in three sizes: mini (diameter 2.5 mm), midi (5 mm) and maxi (10 mm). Perler beads come in two sizes called classic (5 mm) and biggie (10 mm). Pyssla beads (by
IKEA
) only come in one size (5 mm).

Manufacturing
Modern mass-produced beads are generally shaped by
carving
or
casting
, depending on the material and desired effect. In some cases, more specialized
metalworking
or
glassworking
techniques may be employed, or a combination of multiple techniques and materials may be used such as in
cloisonné
.
Glassworking
Pressed glass beads (matte finish with an AB coating)
Fire polished beads (10 millimetres (0.39 in)) with AB coating
Most glass beads are
pressed glass
, mass-produced by preparing a molten batch of
glass of the desired color
and pouring it into molds to form the desired shape. This is also true of most
plastic
beads.
A smaller and more expensive subset of glass and lead crystal beads are cut into precise faceted shapes on an individual basis. This was once done by hand but has largely been taken over by precision machinery.
"Fire-polished" faceted beads are a less expensive alternative to hand-cut faceted glass or crystal. They derive their name from the second half of a two-part process: first, the glass batch is poured into round bead molds, then they are faceted with a grinding wheel. The faceted beads are then poured onto a tray and briefly reheated just long enough to melt the surface, "polishing" out any minor surface irregularities from the grinding wheel.
Specialized glass techniques and types
Dichroic beads (10 millimetres (0.39 in))
Furnace glass beads
There are several specialized glassworking techniques that create a distinctive appearance throughout the body of the resulting beads, which are then primarily referred to by the glass type.
If the glass batch is used to create a large massive block instead of pre-shaping it as it cools, the result may then be carved into smaller items in the same manner as stone. Conversely, glass artisans may make beads by
lampworking
the glass on an individual basis; once formed, the beads undergo little or no further shaping after the layers have been properly
annealed
.
Most of these glass subtypes are some form of
fused glass
, although
goldstone
is created by controlling the reductive atmosphere and cooling conditions of the glass batch rather than by fusing separate components together.
Dichroic glass
beads incorporate a semitransparent microlayer of metal between two or more layers.
Fibre optic
glass beads have an eyecatching
chatoyant
effect across the grain.
There are also several ways to fuse many small glass canes together into a multicolored pattern, resulting in
millefiori
beads or
chevron beads
(sometimes called "trade beads"). "Furnace glass" beads encase a multicolored core in a transparent exterior layer which is then annealed in a furnace.
More economically, millefiori beads can also be made by limiting the patterning process to long, narrow canes or rods known as murrine. Thin cross-sections, or "decals", can then be cut from the murrine and fused into the surface of a plain glass bead.
Shapes
Round
This is the most common shape of beads that are strung on wire to create necklaces, and bracelets. The shape of the round beads lay together and are pleasing to the eye. Rounds beads can be made of glass, stone, ceramic, metal, or wood.
Square or Cubed
Square beads can be to enhance a necklace design as a spacer however a necklace can be strung with just square beads. The necklaces with square beads are used in
Rosary
necklaces/prayer necklaces, and wooden or shell ones are made for beachwear.
Oval
Tube

Today these beads are commonly made of
bison
and
water buffalo
bones and are popular for breastplates and chokers among
Plains Indians
. Black variations of these beads are made from the animals' horns.
Seed beads
Main article:
Seed bead
Seed beads are uniformly shaped spheroidal or tube shaped beads ranging in size from under a millimetre to several millimetres. "Seed bead" is a generic term for any small bead. Usually rounded in shape, seed beads are most commonly used for
loom
and
off-loom
bead weaving.
Place or period of origin

African trade beads
or
slave beads
may be antique beads that were manufactured in Europe and used for trade during the colonial period, such as chevron beads; or they may have been made in West Africa by and for Africans, such as Mauritanian
Kiffa beads
, Ghanaian and Nigerian
powder glass beads
, or African-made brass beads.
Austrian crystal
is a generic term for cut lead-crystal beads, based on the location and prestige of the
Swarovski
firm.
Czech glass
beads are made in the
Czech Republic
, in particular an area called
Jablonec nad Nisou
. Production of glass beads in the area dates back to the 14th century, though production was depressed under communist rule. Because of this long tradition, their workmanship and quality has an excellent reputation.
Vintage beads
, in the collectibles and antique market, refers to items that are at least 25 or more years old. Vintage beads are available in materials that include lucite, plastic, crystal, metal and glass.

History of Beads
Beads are known to be one of earliest forms of trade between the human race. It is thought that is because of bead trading that humans developed language.
[

]
Beads are said to have been used and traded for most of our history. The oldest beads found to date were at
Ksar Akil
, in Lebanon.
[

]
Prior to this find, the beads found in the
Blombos Cave
were the oldest at about 72,000 years old.
Surface patterns
After shaping, glass and crystal beads can have their surface appearance enhanced by etching a translucent frosted layer, applying an additional colour layer, or both.
Aurora Borealis
, or AB, is a surface coating that diffuses light into a rainbow. Other surface coatings are vitrail, moonlight, dorado, satin, star shine, and heliotrope.
Faux beads are beads that are made to look like a more expensive original material, especially in the case of fake
pearls
and simulated rocks,
minerals
and
gemstones
. Precious metals and
ivory
are also imitated.
Tagua nuts
from South America are used as an ivory substitute since the natural
ivory trade
has been restricted worldwide.
