To keep copper’s color after firing fused glass, apply copper without air bubbles at a lower temperature. Heat the glass evenly and gradually. Cool slowly and anneal to relieve stress. Remove oxidation from glass edges to prevent color changes. Use polishing for a smooth, glossy finish.
Maintain a specific temperature for an adequate duration. This ensures the copper reacts and develops a rich hue. After reaching the optimal temperature, cool the glass slowly. A slow cooling process reduces the risk of color loss.
Additionally, consider using a clear glass layer on top to protect the copper color. This can enhance the vibrancy while safeguarding it from abrasion and environmental factors.
Following these tips will help create beautiful fused glass pieces with a lasting copper hue.
In the next section, we will explore advanced techniques to enhance color stability further, including the use of specific glass brands and additives that can amplify the copper effect while providing additional longevity.
