Making of Aerosculpture

 

Technical Production

First, I started by experimenting with dry ice evaporation. When the shiitake mushroom broth was evaporated with dry ice, it smelled of forest, while the kelp broth had the scent of the sea. Even the same aroma smells completely different from our usual perception of it because dry ice evaporates aromas at a lower temperature (-70 degrees C)  than the atmosphere (+-20 degrees C).  I understood then that ancient Japanese cuisine, in which both types of dashi are used in abundance, conceptually expresses the forest and the sea.

The next step was fragrance composition.  The combustion temperature of incense is 800-1000 degrees Celsius, and it was extremely difficult to express this in liquid perfume because the evaporation mechanism is different and the temperature difference is large. As a result, I assembled the fragrance using mainly agarwood accords, sandalwood, patchouli and other fragrances used in burning incense. It was then adjusted for water-base fog liquid in order to use a lower fog machine (ADJ Miter Kool II ) to produce large quantities of smoke.

Some Q & A on Invisible White with students studying architect

Recently I receive a lot of questions from academic side - I am happy that many people study my works. I am answering them as much as I can.

---
• Could you briefly describe one of your favourite projects connected with smells? What were the reasons for using olfaction as a crucial way of perception?

Spatial questions

Invisible White
https://www.ueda.nl/index.php?option=com_content&view=category&layout=blog&id=290&Itemid=836&lang=en


• Did you adapt your work to the space, or did you adjust the space to your work?

Yes and no. It was a collaboration project with an architect. The pavilion was temporarily installed in an office room of an office chair company Okamura
https://www.okamura.co.jp/company/showroom/
https://www.shigotoba.net/okamura_1612_1_letsgoshowroom.html

So the architect came up with an idea constucting a space made only with R(curves).  In the process I requested to make 3 inlets and 1 outlet.

• How many visitors could be the public of this project at a time? 

1 group.

• What size of the exhibition space did your project need? Leight/length/width? 

about 10m x 10m, height 2-3 m.

• Was one room enough? If not, what was the route?

yes.
 

• What means of smell spreading did you use?

Three different liquid fragrance at 15% solutions in solvents, a mixture of ethanol and DPG.
 

• Did you use several smells in one exhibition space? If yes, what means of separation did you use?

Yes.  I did not separate them.  I made use of the natural character of air turbulence that mixes up the fragrances.

Visual questions 

• What was the importance of visual perception in your work? Were there special visual conditions of the exhibition space necessary? What kind of interior design was preferable?

No visual perception was preferred, but literary totally darkness was not preferred.  To ensure audience move freely in the space, the sense of sight had to be active. So we made a small tiny hole in the end of the construction process. There was a slight natural light coming in from the end of the space to help audience locate themselves.
 

• Did the amount of light in the space influence the perception of your work?

Totally. BTW this tiny hole (5cm diameter) made somehow a shiny reflection in the space, somehow.  It happened without planning.  This reflection made the internal air look foggy, so it was a wonder. People asked us if we are making smogs, but we were not.  The fragrance was quite invisible. This effect made audience noticing smells better.

Climate questions
• What was the significance of temperature in your project?

Very important.  +- 23 degrees I prefer.

• What was the significance of the level of humidity in your project?

Very very important. 50-60 percent I prefer.  The museum condition is ideal.
 

• What was the significance of ventilation in your project?

This was something I did not have much control over, because we had to rely on the ventilation that the office space already had.  That is why I made only 1 outlet. 

Other senses questions
• What was the importance of other ways of perception in this project? Did you use music? Tactile models?

No, I prefer not.

Advice
• Would you like to give us advice on how to create a comfortable space for the exposure of odours?

That is a difficult question….
Off course a lot of exhaust option is ideal.  For example the exhausts are placed in grids and if you can switch on and off one by one, that would give us freedom.  
It also needs partitions that seals the space off course.  And the space size has to be flexible (sometimes artwork needs only tiny space, and it cannot be placed in any bigger space) so if partitions can be placed anywhere that would be fantastic.
And off course there needs automated door with air curtain(partition) that prevents odour to leak.

 
Off course temperature and humidity is important.
 

Cafe, bar, restaurant, WC and ticket counter or something like that have to be somehow outside of these space not to interfere each other.
