Introduction

In this tutorial, we will explore how to use air chasing techniques on copper and achieve a stunning blue patina finish. This guide will take you step-by-step through the process, providing practical tips and insights to enhance your metalworking skills.

Step 1: Prepare Your Workspace and Materials

Before starting your project, ensure you have the right tools and a clean workspace.

• Gather the following materials:

  • Copper sheet
  • Air chasing tools (such as chasing hammer, ball peen hammer)
  • Protective gear (gloves, safety glasses)
  • Patina solution (such as liver of sulfur)
  • Water for rinsing
  • Soft cloth for polishing

• Set up a comfortable work area with adequate lighting and ventilation.

Step 2: Design Your Copper Piece

Create a design that you wish to chase into the copper. This can be anything from simple textures to intricate patterns.

• Use a pencil or marker to sketch your design on the copper sheet.
• Consider using templates or drawing freehand, depending on your skill level.

Step 3: Begin Air Chasing

Now it's time to bring your design to life using air chasing techniques.

• Hold the chasing tool at a 45-degree angle against the copper surface.
• Use a steady, controlled motion with the chasing hammer to create your desired pattern.
• Work slowly and steadily to avoid damaging the copper.

Step 4: Refine Your Design

After initial chasing, refine the details of your design.

• Go over the chased areas to deepen the impressions.
• Use different tools for varying effects, such as a ball peen hammer for rounded textures.
• Regularly check your progress to ensure you are satisfied with the look.

Step 5: Clean the Copper Surface

Once you have completed the chasing, it’s important to clean the copper before applying the patina.

• Rinse the copper piece with water to remove any debris or oils.
• Use a soft cloth to gently dry the surface.

Step 6: Apply the Patina

To achieve a blue patina finish, follow these steps for applying the patina solution.

• Prepare your patina solution according to the manufacturer's instructions.
• Use a brush or cloth to apply the patina evenly across the copper surface.
• Allow the patina to sit for the recommended time to develop the desired color.

Step 7: Rinse and Polish

After the patina has set, rinse and polish your copper piece.

• Rinse the copper piece thoroughly with water to remove excess patina.
• Use a soft cloth to buff the surface and enhance the shine.

Conclusion

You have now successfully used air chasing techniques on copper and applied a beautiful blue patina. Remember to experiment with different designs and patina solutions to find what works best for you. Practice will improve your skills, so don’t hesitate to try new techniques. Happy crafting!
