Olfactory art or Scent art has been growing over recent years, And I would agree with the premise, that ‘it has been long disregarded as one of the lower senses’ [scentart.net] I remember turning up for the opening of my own exhibition and discovering that along with the beverages, a selection of delicious snacks had been presented on tables placed inside the gallery space. The smell of the food filled the gallery and I felt at the time that this took away from the work. The smells that would have accompanied the work would have been, hot electronics and detergent. perhaps a hind of coffee from another experiment. Here are a few links to useful sites/research on the subject:
“The sense of smell has long been disregarded as one of the lower senses. More recently, however, the cultural and social relevance of the sense of smell is increasingly recognized” https://scentart.net/about/
“Baltan is both a network and a methodology: It sees the lab as a way of working and as a place where ideas are put into practice through projects in which freedom of thought, openness towards the unknown, experiment and playfulness are key.
Baltan stimulates a cross-disciplinary approach conducted in an open-minded atmosphere based on trust, empathy and mutual inspiration.” http://baltanlaboratories.org/about
