To rewet jelly gouache, add water (more than you think you need) and let it sit overnight.
Here's a breakdown of the process:
- Assess the Gouache: Determine how dry the gouache is. Is it slightly hardened or completely dried out and cracked?
- Initial Hydration: Add a small amount of water to each compartment of the jelly gouache. This initial softening helps prepare the gouache for deeper rehydration.
- Increased Water Addition: If the initial hydration is insufficient, add more water than you anticipate needing. It's better to err on the side of too much water initially.
- Soaking Time: Allow the gouache to sit overnight (or for an extended period). This allows the water to fully penetrate and rehydrate the pigment.
- Check Consistency: After soaking, check the consistency. It should be creamy and easily workable. If it's still too thick, add a little more water and mix.
By following these steps, you can successfully revive your dried-out jelly gouache and bring it back to its former glory.
