Survey on "Alligatoring in Oil Paintings"

This survey is part of a PhD thesis, taking place at the Department of Conservation and Restoration of the NOVA School of Science and Technology, that explores an oil paint defect referred to as "Alligatoring" or "Bitumen Cracking".
The aim is to address the following questions regarding the perception of this defect:
Is this phenomenon well recognised?
Is it considered to be widespread?
What do people see as the dominant characteristics of this type of defect?
What is the relationship between the severity of the defect and the choice of whether or not to exhibit affected paintings, or whether aesthetic treatments should be carried out?
The survey has images, is anonymous and takes approximately 5 minutes altogether. It can be accessed here
