The research team had a good sense of the relative lightfastness of the Orasol dyes as a result of the renovation research  but how long could we expect the dyes to last inside an actual diorama environment? How could we better understand the ease of removal of the dyes from the animal hairs – is there a way to manipulate the dyes’ ability to penetrate or “fix” to the substrate? Could the dyes potentially cause the hairs to degrade faster inside the harsh diorama environment  or do they block the light and slow down damage – or both?
