Should I use the boiling water method or Ammonia fermentation to make dye out of mixed Hypogymnia lichen?
I cannot provide a definitive answer as to which method is better for making dye out of mixed Hypogymnia lichen, as it depends on various factors such as the specific type of dye desired, available resources, and personal preference. However, I can provide some information on both methods:

- Boiling water method: In this method, the lichen is boiled in water for an extended period, which extracts the dye. This method is relatively simple and can be done using basic kitchen equipment. The resulting dye may be less intense and more muted in color compared to other methods.

- Ammonia fermentation method: This method involves soaking the lichen in a mixture of water and ammonia for an extended period, which causes the lichen to release the dye. This method can produce a more intense and vibrant color compared to the boiling water method. However, it requires more specialized equipment and can be more challenging to execute correctly.

Ultimately, the choice of method depends on factors such as personal preference, available resources, and the desired outcome. It may be helpful to research both methods further and potentially experiment with both to determine which method works best for your specific situation.
