Should I use the boiling water method or Ammonia fermentation to make dye out of mixed Hypogymnia lichen?

Both the bo iling water method and Am mon ia fer ment ation can be used to make d ye from mixed H yp og ym nia lic hen . However , the bo iling water method is more commonly used and is generally considered to be more effective . It involves bo iling the lic hen in water for several hours , then str aining the liquid and using it as a d ye . Am mon ia fer ment ation involves adding am mon ia to the lic hen and allowing it to fer ment for several days , then using the resulting liquid as a d ye . Both methods can produce a range of colors , but the bo iling water method is generally more reliable and consistent . It is important to follow safety prec aut ions when using either method , such as wearing gloves and working in a well - vent il ated area . </s>
