This week we feature our Wax Casting Supplies

Looking for wax casting supplies and accessories? Look no further! We have you covered from wax to wax molds and wax injectors!

Today we feature a few of our Wax Casting Supplies from our sister site JewelryTools.com.

What is Wax Casting?

Lost-wax casting is the process by which a duplicate sculpture or jewelry piece (often silver, gold, brass or bronze) is cast from an original sculpture. The “lost wax” technique is so called because the wax model is destroyed in order to create the piece. The technique is sometimes called the “lost mold” technique because the mold, too, is destroyed in the process.

Wax Working Tools:

Below we feature a selection of tools that are necessary for any beginner to advanced artisan.

What is Patina?

Daily Wire Jewelry Tip February 27, 2015

What is Patina?

After we posted our Liver of Sulfur tutorial on Monday, we had quite a few questions come in from our readers. So, today I thought we’d address a these questions.

What is patina?

Patina is a film that develops on the surface of metal over a period of time. Due to exposure to open air and the natural process of oxidation, an aged metal such as copper and silver tends to develop a patina. Because it can take from days to years for patina to occur naturally, we can speed up the process for jewelry-making purposes and create the patina ourselves. One of the more commonly used patinas is Liver of Sulfur (LOS).

Liver of Sulfur:

Liver of Sulphur Gel, 2 Ounce Bottle

Liver of Sulphur Gel, 2 Ounce Bottle

Formulated for extended shelf life, versatility and convenience, this gel makes it easy to use and less mess with better results. May be used in concentrate or diluted in warm water for desired effect. 2 oz. squeeze bottle. Non-hazardous.

Liver of Sulfur 4 oz

Liver of Sulfur 4 oz

Liver of sulfur is traditionally one of the best oxidizers for silver and other metals. It produces a durable black finish. Simply dissolve in hot water. 4 oz jar comes in lump form.

Ultra-Polish Pads, 5 pack

Ultra-Polish Pads, 5 pack

These convenient sized Ultra-Polish Pads are great for removing tarnish, highlighting when using liver of sulfur or silver black, or polishing to a high luster, fast and easy. Leaves no residue. They are made of thin, tight-bond foam with permanently bonded micro-abrasives. A handy, economical polisher that is truly amazing. Squares are 2″ x 2″ and sold in packs of 5.

5 Types of Patina:

Here are five additional Patina finishes that you can achieve with a little experimentation. The following techniques begin with the basic process of using Liver of Sulfur. Additional materials or tools are listed.

1. Traditional Antiquing: Black crevices, bright highlights)

Additional supplies:

Scratch brush a piece and burnish it or tumble for 45 minutes or more to a mirror finish. Use the LOS to patina the piece to a dark black. For faster results, work with hotter temperatures and longer soaking, and build color gradually versus doing it in one big jump. After a final soapy rinse, dry the piece and rub “highlights” off with a polishing cloth. See the drama and depth that you have created!

2. The look of hematite:

Additional supplies:

This method will take the “Traditional antiqued” method to the next level, coloring the metal a reflective, deep gray-to-black similar to the mineral hematite. After applying the patina, you may choose to remove or not remove highlights with a polishing cloth. Put the piece in the tumbler, add 1-2 tablespoons of hand soap or the recommended amount of a burnishing solution, and then add water to about an inch above the shot. Tumble for 20-30 minutes. Wow, what sheen!

3. Steely gray/blue-gray brushed finish:

Additional supplies:

  • Non abrasive hand soap

Progress through coloring a piece until you reach a gray or blue-gray. Use a steel or brass brush and a bit of hand soap to scratch brush the surface for a steely effect. More brushing will lighten the color, and a stiff brush will be more aggressive than a soft one. This is a soft and subtle patina that can have a sophisticated look!

4. Layered color:

Additional supplies:

Use any LOS recipe to develop one or two shades past gold or light brown, stopping with a cold-water bath. Brush or selectively remove color from portions of the piece with a polishing cloth. Then, wash in soapy water to remove hand oils and polish, and then dip again in LOS. You’ll notice the un-removed patina will continue to darken, while the area where the patina was removed becomes gold.

Also, try detailing the LOS in selected areas. Put the piece on a cup warmer and apply LOS with the brush. Be sure other areas have no LOS residue on them or they will darken as well. Before detailing, wash the piece in the sudsy, baking soda water mix.

5. Iridescent effects:

Additional supplies:

  • Ammonia

Adding a tablespoon of ammonia to the LOS solution kicks the process up a notch. Colors intensify and have an iridescent effect. Gold’s become brighter, blues more saturated, and the purples pop. Ammonia, in my opinion, adds an additional element of wonder because it seems to make the LOS solution more “sensitive.” You are likely to get a tonal range instead of flat color. For instance, a pink area may have a subtle pink to bright magenta. If you are particularly interested in a specific effect, a test piece may be in order. Be adventurous and watch how a kick of color can change your whole piece!

Now let’s answer a few additional questions:

1. Will Liver of Sulfur patina to gold-filled metals?

  • No, gold alloys will not react to most sulfur solutions.

2. Will Liver of sulfur give patina to fine silver?

  • Yes, the copper content in silver reacts with the LOS to result in a patina. Even though fine silver is 99 percent silver, it has sufficient copper to result in a beautiful patina.

3. Will Liver of sulfur patina to brass?

  • No, Brass will not react to most sulfur solutions.

4. Will Liver of Sulfur patina to copper?

  • Yes LOS will patina copper but you would use cold water.

5. Will Liver of Sulfur affect gemstones?

  • Cubic zurconia, glass and man-made gemstones will be unharmed by LOS.
  • Most natural gemstones will be unaffected with some exceptions. Turquoise, Lapis, shell, pearls and other soft stones should not come into contact with LOS as they are porous and could be damaged.

What about Metal?

We also had a couple of questions about metal and what kind you can use and the types of finishes it would produce. Below is a quick reference guide to the range of colors possible when used with a specific metal type.

Metal

Range of color possible

Fine Silver Straw gold, green, pink, blue, purple, gray and black
Sterling Silver Straw gold, green, pink, blue, purple, gray and black
Argentium sterling silver Straw gold, green, pink, blue, purple, gray and black
Brass Brown to black tones
Bronze Brown to black tones
Copper Brown to black tones
Gold None to very pale brown depending on karat

Liver of Sulfur Finish

Daily Wire Jewelry Tip February 25, 2015

Liver of Sulfur Finish

We’ve been discussing patina’s and finishes around the office the last few days.. so today, I thought I’d re-visit an older post about using Liver of Sulfur to give your jewelry pieces an antique look.. This is an easy process which can give your wire work a great finish!

What is Liver of Sulfur?

Liver of sulfur, also spelled liver of sulphur or just LOS, is a quick and easy (although stinky!) way to patina copper and silver. Liver of sulfur, though, will give your copper and silver jewelry a beautiful antique look like the one featured below.

Quick Wired Bead Ring by Albina Manning

Note: there are 2 types of liver of sulfur available on the market: gel and “rock” or solid form. I highly recommend the gel form, available here: Liver of Sulphur Gel, because the gel dissolves in warm water much faster, making the process (and the smell!) faster than ever.

Here’s a little tutorial that will show you how easy it is to use liver of sulfur!

Materials needed:

  • Liver of Sulphur Gel
  • Water in a glass or plastic cup (I recommend disposable)
  • Paintbrush
  • Fine (#0000) Steel Wool and a Dust Mask
  • Paper towels and/or rags
  • Disposable Gloves that will keep your fingers dry
  • and of course, the pieces you want to patina!

Step 1. Clean your piece and set up your equipment. Plan ahead of time where you’ll process your jewelry, and remember that it will smell like eggs. I set up out on the porch, with the house door closed.

Supplies for a liver of sulfur patina

A cup with water, Liver of Sulfur Gel, #0000 Steel Wool, Gloves, and a Paintbrush.

Step 2. Read the directions on your package. For the gel form of liver of sulfur. Typical directions will ask for warm, not hot water, that you can still put your finger in and not be burned. An easy way to do this is simply place the water in the microwave for 20-30 seconds. The amount of water you’ll need depends on how much jewelry you’ll be patina-ing, but a small cup with about 8 ounces of water will easily do dozens of earrings.

Step 3. Take the water out of the microwave and bring it to your work station. Remember, this should be outside or in a well-ventilated area! Now, put on gloves: you don’t want to touch liver of sulfur to your skin. Add your liver of sulfur to the water (check your directions for how much) and stir with your paintbrush. With just a small cup (about 8oz), about 5 drops of liver of sulfur is strong enough. You can always add more gel. If you aren’t using the gel form, you will have to allow time for the liver of sulfur to dissolve. It will be bright yellow when it’s ready.

Stir the Liver of Sulfur solution to mix it

Step 4. Here’s the fun part: in goes the jewelry!
It’s up to you to use tweezers or tongs, or to simply pull the jewelry out of the liver of sulfur solution with your gloved fingers. If you used a lot of liver of sulfur, the jewelry will turn black almost immediately. If you used less, you may have to let it sit in the solution for up to a minute.

Hint: If you have items you don’t want the liver of sulfur to touch, such as pearls, use a paintbrush (or even a q-tip) to only apply the liver of sulfur to the area of the piece you want to have patina.

Painting liver of sulfur on copper with a paintbrush

Step 5. Remove the blackened jewelry from the liver of sulfur. Let sit on a towel or rag to dry.

Step 6. When dry, use #0000 fine steel wool to erase some of the blackened finish, revealing a lovely antique look.

Hint: Fine steel wool can “shed,” so do this over a work surface. I use a paper towel to hold the steel wool so I don’t get poked! Safety note: it’s a good idea to wear a dust mask while using steel wool.

Polishing liver of sulfur with steel wool

Step 7. Rinse with clean water, and let your piece dry. Leave as-is, or seal with wax like Renaissance Wax to protect your new patina. Now, admire your work!

To dispose of the liver of sulfur, simply pour it slowly down the drain with lots of running water. An even safer method is to shake baking soda into the liver of sulfur to neutralize it, then pour it down the drain (good for old pipes).

February Birthstone: Amethyst

February BirthstoneAmethyst is a violet variety of quartz. A stone of wisdom, February’s Amethyst draws forth one’s intuition in order to bring clarity to emotions, feelings, and values. Amethyst is a semiprecious stone and is the traditional birthstone for February. Amethyst owes its violet color to irradiation, iron impurities, and the presence of trace elements.

Let’s take a look at the history of Amethyst and what makes it so beautiful!

Amethyst

Amethyst Cluster

Amethyst cluster from Magaliesburg, South Africa.

Hue and Tone

Amethyst occurs in primary hues from a light pinkish violet to a deep purple. Amethyst may exhibit one or both secondary hues, red and blue. The best varieties of Amethysts can be found in Siberia, Sri Lanka, Brazil and the far East.

14X7mm Marquise Light Amethyst CZ - Pack of 1

The ideal grade is called “Deep Siberian” and has a primary purple hue of around 75–80%, with 15–20% blue and (depending on the light source) red secondary hues.

15x20mm Rectangle Amethyst CZ - Pack of 1

History:

Amethyst was used as a gemstone by the ancient Egyptians and was largely employed in antiquity for intaglio engraved gems.

Roman intaglio engraved gem of Caracalla in amethyst, once in the Treasury of Sainte-Chapelle.

The Greeks believed amethyst gems could prevent intoxication, while medieval European soldiers wore amethyst amulets as protection in battle in the belief that amethysts heal people and keep them cool-headed.

Beads of amethyst were found in Anglo-Saxon graves in England. Western Christian bishops wear an episcopal ring often set with an amethyst, an allusion to the description of the Apostles as “not drunk” at Pentecost.

Synthetic Amethyst:

Synthetic amethyst is produced by gamma-ray, x-ray or electron beam irradiation of clear quartz which has been first doped with ferric impurities. Synthetic amethyst is made to imitate the best quality amethyst. Its chemical and physical properties are so similar to that of natural amethyst that it can not be differentiated with absolute certainty without advanced gemological testing.

Where it’s found:

Amethyst is produced in abundance in Brazil where it occurs in large geodes within volcanic rocks. It is also found and mined in South Korea. The largest opencast amethyst vein in the world is in, Lower Austria. Much fine amethyst comes from Russia, but one of the largest global amethyst producers is Zambia in southern Africa with an annual production of about 1000 tons.

An amethyst geode that formed when large crystals grew in open spaces inside the rock.

Amethyst occurs at many places in the United States. Among these are the Mazatzal Mountain region in Gia and Maricopa Counties, Arizona, Red Feather Lakes, near Ft Collins, Colorado; Amethyst Mountain, Texas; Yellowstone National Parke, Pennsylvania, North Carolina, Maine, Wisconsin and Michigan. The largetst amethyst mine in North America is located in Thurdar Bay, Ontario.

Using Amethyst Birthstones and Gemstones:

If you were born in February you probably already know all about amethyst because it’s your birthstone. Did you also know that it’s the 9th wedding anniversary gemstone? This gorgeous, deep purple colored stone twinkles and shines in the light. Our dark amethyst cubic zirconia will be a hit for any project! Pick out your amethyst CZ today!
