Acetate looks similar to Lucite (acrylic resin), but this form of plastic actually begins with acetic acid (also known as household vinegar), combined with various bases to give it the desired colors and texture. Acetate charms, connectors
and other components are strong, lightweight, slightly flexible, and remarkably hypoallergenic. This combination makes it popular for eyeglass frames as well as jewelry. custom air jordan shoes

Alkeme metal stamping blanks by ImpressArt
are a nice alternative to sterling silver blanks. They're made in the USA from a specially formulated, non-corrosive metal alloy that is lead free, nickel free, and cadmium free. The resulting soft metal allows even intricate and delicate stamping designs to make complete impressions and look great. Customize silver colored Alkeme blanks with metal stamps, texture hammers, and more. They can also be used for riveting and engraving.custom air jordan shoes
Aluminum is a soft metal, which makes it easy to stamp, emboss, and otherwise shape with jewelry tools. Our aluminum sheet and blanks are made of elemental aluminum, meaning our aluminum is simply aluminum: it is not alloyed with other metals. In other words, it does not contain nickel or other additives that require warnings in California or are banned in jewelry in the EU. Some advantages to aluminum: it does not tarnish. The flipside of this, is that you can't oxidize it with standard jewelry antiquing solutions. However, you can purchase anodized aluminum
in brilliant colors, or you can use alcohol inks or Vintaj "patinas"
to colorize textured aluminum. Keep in mind that aluminum's softness also makes it easy to scratch, so use care with working with aluminum. Use nylon-jaw pliers, or dip your tools in Tool Magic
to help prevent scratches.custom air jordan shoes
The majority of our bone beads and pendants are camel, yak or water buffalo bone, hand carved in India. Our suppliers have assured us that no animals were harmed for these jewelry-making supplies; the bone and horn used is from animals that died of natural causes, or is simply a way to utilize "the rest of" an animal rather than wasting the bone. These beads and pendants are wonderful for handmade jewelry, but please be aware that all hand-carved items vary in size, color, pattern and quantity per strand, so they're not the best choice for people who need perfectly matched pairs. Want a different color?
For a natural antique look, try soaking any of the white bone beads in tea, coffee or ink to simulate old ivory. Experiment with different liquids to find your preferred color(s)! Whatever antiquing method you use, be sure to wash your items well and test your antiquing for "colorfastness" before making finished jewelry.custom air jordan shoes
Brass is an alloy of copper, zinc and sometimes other metals. Our brass is typically 70% copper
and 30% zinc
, but may vary between 70% and 90% copper (with zinc as the remainder).
custom air jordan shoes
- Our custom air jordan shoes is 90% copper and 10% zinc, giving it a slightly warmer color than standard brass.
- custom air jordan shoes components are usually a good match for yellow (plated) findings, although they will vary in color and may also work with gold plate. The surfaces of raw brass items may be imperfect, and require polishing, and their finish may change with age.
- custom air jordan shoes (a proprietary alloy) looks very close to the color of 14kt gold. Another name for anti-tarnish brass is tarnish-resistant brass.
Britannia is a pewter alloy with a silvery appearance and smooth surface. It is an alloy of tin, antimony, and copper. Most TierraCast Britannia pewter beads and jewelry findings have a surface finish (plating) of a different color over the pewter base. TierraCast Safety Compliance Info.custom air jordan shoes

Carbon Steel is an alloy of steel with carbon content up to 2.1%. Carbon steel has the ability to become harder and stronger through heat treating, but it also becomes less ductile (i.e., less malleable). In other words, you would not want to use carbon steel for wire-wrapping, but it's great for metal stamps, and for springy coils of memory wire. One downside to carbon steel, is it lacks the rust-resistance of stainless steels
.custom air jordan shoes
Ceramic is fired clay. The majority of our ceramic beads are hand-painted. Some of our ceramic pendants and beads have a raku-style multicolored glossy glaze, and others have a natural earthy-looking high-fired finish. What's the difference between porcelain and ceramic? Porcelain is a more-refined type of ceramic, with a finer texture, and can be glassy and semi-translucent. custom air jordan shoes
Copper (Cu) is an elemental metal that is bright reddish-orange in color, and has the atomic number 29. It's a very reactive metal, meaning over time, it will darken and gain a patina, sometimes with a greenish hue. Copper can also discolor skin, most commonly when it is worn snugly like a ring or tight-fitting bracelet. Copper is a soft metal, which makes it great for wire wrapping. Because of copper's softness, solid copper components may bend easier than copper-plated beads and findings. Unplated copper is usually called raw copper
or bare copper. custom air jordan shoes

Czech Glass is simply the Material name we've given to our glass beads that are made in the Czech Republic. The Czech Republic includes the historical territories of Bohemia, Moravia, and Czech Silesia. Faceted firepolish beads
have been under production for centuries (they were formerly called Bohemian glass beads), and Czech pressed-glass beads
are well-known around the world. custom air jordan shoes
Our gemstone beads, pendants and findings are cut from a wide variety of semiprecious stones (mineral crystals) including agates and jaspers, and occasionally lower-quality "bead quality" precious gemstones such as sapphires, rubies and emeralds. Nearly every gemstone category in the Gemstones & Pearls
section of our website includes physical properties of the stone, historical and metaphysical information if possible, and any special care instructions that may be necessary for some types of gemstones. This information is usually at the top of the page, but sometimes flows to the bottom of the category. custom air jordan shoes
Glass is a non-crystalline amorphous solid. It's usually based on the chemical compound silica (quartz), with many other "ingredients" depending on the desired properties and color. Traditionally, most brilliant true reds contained gold, making good red glass more expensive than other colors of glass. custom air jordan shoes
Gold Fill (also called custom air jordan shoes
) is made by using heat and pressure to apply a layer of karat gold
to a base of less costly metal. This produces a surface with karat gold. The minimum layer of karat gold must equal at least 1/20 of the total weight of the item. This layer of gold is 17 to 25,000 times thicker than the layer of gold on gold plated jewelry.
Gold-filled tubing and wire are usually seamless
, so only gold touches the body. Gold-filled sheets of base metal, used to make other findings, can be either single clad
(gold on visible side only) or double clad
(gold on both sides and sometimes the edge). Seamless and double clad gold-filled items are less likely to discolor, since the base metal is sealed inside the gold. However, the layer of gold on a single clad 1/20 gold-filled item is as thick (and the same total weight) as the two layers of gold on a double-clad 1/20 gold-filled item.Use care when buffing gold-filled items, to avoid removing the gold layer.
The surface layer of karat gold on gold-filled items is usually 10kt, 12kt or 14kt (custom air jordan shoes
). To know the thickness of the layer, look for a stamped fraction, such as 1/10 or 1/20. It is always 1/20 unless otherwise stamped.
Examples:custom air jordan shoes
1/10 of the total weight is 10kt gold.custom air jordan shoes
1/20 of the total weight is 12kt gold. custom air jordan shoes
The majority of our horn beads and pendants are made from water buffalo horn, hand carved in India. Black and "natural" are usually the horn's original color without any treatments or dyes. Gold and red horn may be bleached and/or dyed. Dyed horn beads and pendants might not be colorfast. Our vendors have assured us that no animals were harmed for these; the horn used is from animals that died of natural causes. Our hand-carved horn beads and pendants are wonderful for handmade jewelry, but please be aware that all hand-carved items vary in size, color, pattern and quantity per strand, so they're not the best choice for people who need perfectly matched pairs.custom air jordan shoes
Swarovski Spectra lead-free rainbow crystal offers above-average results regarding light reflection and brilliance while delivering excellent value for money. While It makes beautiful jewelry centerpieces as well as sun-catchers to display in your business, home or car. It is the perfect choice for the price-conscious consumer. custom air jordan shoes
Glass with lead oxide (PbO) has a higher density, giving it a high refractive index, which makes it extra brilliant. It's a bit more fragile than other types of glass, and easier to cut than many other types of glass. Lead Glass with between 24% and 32% lead oxide, and the proper faceting, produces brilliant rainbows, sparkling rhinestones and beautiful cutware. However, it's not safe to store wine or other acidic beverages in lead-crystal decanters, and due to the hazards of working with lead, and concerns about infants and children swallowing lead-based beads, it is no longer as popular in jewelry and cutware, stemware and decanters as it was in previous centuries. custom air jordan shoes
Pewter includes any of the numerous silver-gray alloys of tin with various amounts of antimony and copper. Old/vintage pewter components frequently contain lead
, because it lowers the alloy's melting temperature. Now, you rarely find pewter that contains lead unless you buy it from a clueless or unscrupulous supplier. (Beware of prices that seem too good to be true! Avoid cheap pewter when making jewelry that might be worn by children or otherwise teethed on or ingested.)
Some of our base-metal items that were made of pewter in previous decades are now made of a brass
alloy base (the "Material" on the Details page of an item), with an antiqued pewter plating (the "Color" on the Details page of an item). custom air jordan shoes
A synthetic material made from any of numerous organic synthetic or processed materials such as polyethylene, PVC, etc., that can be molded into shape while soft and turned into a rigid or somewhat flexible end form.custom air jordan shoes
Stainless Steel (also known as corrosion-resistant steel) is a generic name for any steel
alloy with a minimum of 11.5 wt% chromium. The chromium creates a very thin chromium-oxide layer on the surface of the metal, which prevents it from rusting. The advantage of stainless steels over plated steels is that, if scratched or damaged, the stainless steel 'self-repairs' as a new chromium-oxide layer is formed. In plated steels, scratches in the plating can lead to corrosion of the steel underneath. In general, the higher percentage of chromium, the stronger the corrosion resistance of the steel. Other metals are added to the alloy to give the steel other properties, such as strength and malleability. Nickel is added to strengthen the protective oxide layer.
Stainless steel findings are slightly more gray than white findings, but the difference is barely noticeable, especially on finished jewelry. Stainless steels do not match sterling or silver plate well.custom air jordan shoes
is a term that is falling out of favor in the metals industry, as specific alloy numbers for steel (like 304, 430, and 316L) provide more information about the exact qualities of each type of steel. It's important to know that, while wearable by the majority of the population, custom air jordan shoes
, usually 8% in jewelry. Low-nickel forms of stainless steel (such as 430 stainless steel) do not meet the needs of the medical industry,
as they lack the corrosion resistance that nickel gives to steel.
custom air jordan shoes
- custom air jordan shoes is the most popular grade of stainless steel. It is 18-20% chromium, 8-10.5% nickel, 0.08% carbon, plus iron and the trace elements listed above. It is commonly used in the food industry (sinks, coffee urns, dairy storage and hauling, beer/brewing, citrus and fruit juice handling, etc). The same corrosion and stain resistance that make it great for food handling, also make it popular for jewelry.
- custom air jordan shoes is almost the same as 304, but has a lower carbon content (0.03%), and may contain a slightly higher amount of nickel (8-12%). This alloy has increased weldability and resistance to corrosion (great for men's jewelry).
- custom air jordan shoes contain 2-3% molybdenum for even greater resistance to harsh corrosives (both industrial, and in the body). 316 and 316L stainless steels were some of the alloys formerly called Surgical Stainless Steel, but now they are known by their ASTM alloy numbers. 316L is a low carbon version of 316, with extra corrosion resistance, and is frequently used for stainless steel watches and marine applications. Like most other stainless steel, it contains 8-10.5% nickel, making it unsuitable for people with nickel allergies.
- custom air jordan shoes contains less than 0.75% nickel, and some forms of 430 stainless steel meet the EU nickel directive (less than .05% nickel ion migration). 430 stainless steel has good corrosion resistance compared to non-stainless steel, but not as good as the 304 and 316 alloys. This makes it less popular for jewelry than you would expect from its low nickel content. However, it is gaining in popularity due to the low nickel content, and we now have bead caps in addition to earring findings in 430 stainless steel.

Steel is a blanket term for a wide variety of iron-based alloys
that are very tough and hard. When our item material simply says "Steel", it is generally a tool made of a basic, strong tool steel, or it's the strong base material under a plating
. Many plated chains and findings are made with steel, because it is strong: it doesn't bend out of shape easily, and links don't open on accident (but you may be able to open them with 2 pairs of pliers). Most alloys of steel contain nickel
-- especially if the specific alloy of steel isn't listed -- so raw, unplated steel does NOT match the EU Nickel Directive, unless the item specifically states that it is an acceptable nickel-free alloy. It is possible that some of our plated steel chains are suitable for sale in Europe, but we do not guarantee them. If you would like to give it a try, we suggest you try the platings other than -9 Gunmetal and -1 White. (Gunmetal and White platings occasionally contain nickel.)

Sterling silver, sometimes stamped .925 or simply 925, is an alloy of at least 92.5% silver. The remaining 7.5% is usually copper. All of our sterling silver is nickel-free, cadmium-free, lead-free, and meets the EU Nickel Directive. Sterling silver is a soft, easy to work with metal, which can be antiqued to a dark black or polished to a bright shine. More information about sterling silver custom air jordan shoes

Zinc (Zn) is an elemental metal with atomic number 30. It is silvery in color, and relatively abundant in the earth's crust. It's been used in brass
alloys as early as 2,000 BCE (or even earlier).
