The Properties of Silver

Understanding the properties of silver is essential for successful silversmithing. Silver is a relatively soft, ductile, and malleable metal, making it ideal for shaping and forming. Its high thermal and electrical conductivity also make it suitable for certain applications.

• Malleability: The ability to be hammered or rolled into thin sheets without breaking.
• Ductility: The ability to be drawn into wires.
• Thermal Conductivity: The ability to conduct heat. This is important for soldering and annealing.
• Electrical Conductivity: The ability to conduct electricity.
• Tarnish: Silver reacts with sulfur in the air, causing it to tarnish. Regular polishing is required to maintain its shine.

Sterling silver, an alloy of 92.5% silver and 7.5% of another metal (usually copper), is the most common type of silver used in silversmithing. The addition of copper strengthens the silver without significantly affecting its color or luster. Other silver alloys exist, each with slightly different properties and applications.

Key Silversmithing Techniques

Silversmithing involves a variety of techniques, each requiring skill and practice. Some of the most common techniques include:

Forming Techniques

Forming techniques involve shaping the silver into the desired form. Common methods include:

• Raising: Hammering the silver from the center outwards to create a three-dimensional form. This is often used to create bowls, vases, and other hollowware.
• Sinking: Hammering the silver into a hollow form, such as a dapping block. This is used to create curved shapes and depressions.
• Forging: Shaping the silver by hammering it on an anvil. This is often used to create tools, handles, and other structural elements.
• Stamping: Using a die to impress a design onto the silver.
• Spinning: Shaping the silver by pressing it against a rotating mandrel. This is often used to create cylindrical shapes.

Surface Decoration Techniques

Surface decoration techniques add texture and detail to the silver object.

• Chasing and Repoussé: Chasing involves creating a design on the front of the metal by hammering from the back (repoussé) and then refining the design from the front (chasing). This technique allows for intricate and three-dimensional details.
• Engraving: Cutting lines and patterns into the silver surface using a graver. This technique is often used for adding inscriptions or decorative details.
• Etching: Using acid to corrode away areas of the silver surface, creating a textured or patterned effect.
• Enameling: Fusing colored glass powder onto the silver surface.
• Niello: Filling engraved lines with a black metallic alloy (niello) to create a contrasting design.
• Granulation: Attaching small granules of silver to the surface using a soldering technique. This creates a textured and decorative effect. This technique was used in ancient times, including by Etruscan silversmiths.

Joining Techniques

Joining techniques are used to connect different pieces of silver together.

• Soldering: Using a torch and solder to fuse two pieces of silver together. This is the most common method for joining silver.
• Riveting: Using rivets to mechanically join two pieces of silver together.
• Welding: Fusing two pieces of silver together using heat and pressure. This is a more advanced technique that requires specialized equipment.

The Soldering Process in Detail

Soldering is a fundamental skill in silversmithing. It involves joining two pieces of metal using a filler metal (solder) that has a lower melting point than the base metal (silver). The process requires careful preparation, precise application of heat, and a thorough understanding of the materials involved.

1. Preparation: Clean the surfaces to be joined thoroughly using a degreaser and abrasive. Ensure a tight fit between the pieces.
2. Flux Application: Apply flux to the joint area. Flux prevents oxidation during heating and promotes solder flow.
3. Heating: Heat the metal pieces evenly with a torch. The goal is to bring the entire joint area to the soldering temperature.
4. Solder Application: Apply solder to the joint. Capillary action will draw the molten solder into the gap.
5. Cooling: Allow the joint to cool slowly. Quenching (rapid cooling) can weaken the joint.
6. Pickling: Immerse the soldered piece in a pickling solution (dilute sulfuric acid or a commercial pickling compound) to remove oxidation and flux residue.

Different types of solder are available, each with a different melting point. Hard solder has the highest melting point and is used for the initial soldering steps. Medium and easy solders are used for subsequent soldering operations to avoid melting previously soldered joints.

Finishing and Polishing

Finishing and polishing are essential steps in silversmithing. These processes remove imperfections, smooth the surface, and bring out the shine of the silver.

• Filing: Use files to remove any excess solder or sharp edges.
• Sanding: Use sandpaper with progressively finer grits to smooth the surface.
• Polishing: Use polishing compounds and buffs to achieve a high shine. Different compounds and buffs are used for different stages of polishing. Rouge is a common polishing compound for silver.
• Tarnishing: Intentionally tarnishing the silver can create an antique look or highlight engraved details. This can be achieved using liver of sulfur or other tarnishing solutions.
• Sealing: Applying a sealant can help to protect the silver from tarnishing.

Safety Precautions

Silversmithing involves working with heat, chemicals, and sharp tools. It is essential to take appropriate safety precautions to protect yourself from injury.

• Wear safety glasses to protect your eyes from flying debris.
• Wear a respirator when soldering or working with chemicals.
• Wear gloves to protect your hands from heat and chemicals.
• Work in a well-ventilated area to avoid inhaling fumes.
• Use caution when handling sharp tools.
• Keep a fire extinguisher nearby.
• Be aware of the risks of working with electricity.
