Both torch firing and kiln firing have their merits and considerations. The method you choose depends on factors such as the scale of your project, the equipment available to you, and your desired level of control over the firing process. Always follow the manufacturer's instructions and recommendations for the specific type of metal clay you are working with to ensure successful firing and the desired final result.
Adding Unfired Clay to Fired Clay
During the firing process of metal clay, it is not uncommon for issues such as cracks or imperfections to arise. However, the good news is that these problems can often be repaired by adding unfired clay to the fired clay. Here's how to perform this repair technique:
1. Identify the area in need of repair:
Carefully examine the fired clay piece and identify the specific area that requires repair. It could be a crack, a missing section, or any other issue that needs to be addressed.
2. Select matching unfired clay:
Choose a small piece of unfired clay that matches the type of the fired clay. This ensures that the repaired area blends seamlessly with the rest of the piece. Conditioning the clay by kneading it beforehand will make it easier to work with.
3. Prepare the unfired clay:
Roll the unfired clay into a thin sheet or shape it into a small ball, depending on the size and shape needed to repair the fired clay. Ensure that the unfired clay piece is slightly larger than the damaged area to allow for proper blending and smoothing.
4. Prepare the fired clay: Use a metal file to create some deep groves and scrathes in the metal where the fresh clay will be attached. This helps ensure a good connection.
5. Apply Project X .999 Oil Paste:
Using a brush, apply a small amount of Oil Paste to the area of the fired clay that needs to be repaired. The paste acts as a bonding agent and helps the unfired clay adhere to the fired clay.
5. Place and press the unfired clay:
Carefully place the prepared unfired clay onto the wet area of the fired clay and press it down gently. Ensure that it covers the damaged section completely and makes good contact with the fired clay.
6. Smooth and blend:
Using your fingers or appropriate tools, gently smooth and blend the edges of the unfired clay with the surrounding fired clay. This creates a seamless transition between the repaired area and the rest of the piece. Take your time to achieve a natural and cohesive appearance.
7. Allow drying and firing:
Allow the repaired area to dry completely before proceeding with the firing process. Follow the manufacturer's instructions regarding drying time. Once dry, fire the piece according to the recommended firing schedule for the specific type of metal clay you are using. Proper firing is essential to ensure the bonding and integrity of the repaired area.
By using this technique, you can effectively repair cracks and other issues in your fired metal clay pieces, giving them a second chance and avoiding the need to start from scratch. It's important to practice patience and precision during the repair process to achieve the best results. With time and experience, you'll become more adept at restoring and salvaging your metal clay creations.
