This page Abbaszadeh says that the light installation ‘required numerous iterations’ to achieve the perfect refraction
The process involved trial and error with each droplet contained different concentrations of salt and water, the delicate appearance of light within frozen water achieved through the careful variation of salt concentrations. ‘Achieving the perfect refraction required a delicate balance that necessitated meticulous experiments and adjustments,’ says Abbaszadeh. His hope, says Abbaszadeh, is to see
a general improvement in understanding the the significance of architectural lighting design, and ‘the substantial difference between designing with light and superficially, merely lit, surfaces.’ itawards.com
