To open dried watercolor tubes, try soaking the cap area in water or applying heat. Here's a breakdown of techniques:
1. Soaking in Water:
- The Technique: Immerse only the cap of the watercolor tube in a small amount of water (just enough to cover the cap) and let it soak overnight.
- Why it works: This allows the water to penetrate and soften the dried watercolor paint that's likely sealing the cap to the tube.
- Important: Be careful not to submerge the entire tube, as this can damage the label.
2. Applying Heat (Hot Water):
- The Technique: Run the cap of the watercolor tube under very hot water for about a minute.
- Why it works: The heat expands the metal or plastic of the cap and softens the dried paint, making it easier to twist open.
- Important: Handle the tube carefully as it may become hot.
3. Additional Tips:
- Gentle Pressure: After soaking or heating, try gently twisting the cap with pliers or a wrench (use a cloth to protect the cap from scratches). Avoid excessive force to prevent damaging the tube.
- Needle/Pin: Carefully use a needle or pin to break away any dried paint around the cap before attempting to twist it open.
- Patience: Sometimes, it takes repeated attempts with soaking and heating to loosen the dried paint.
