The composition of the Butterfly Wing glaze consists of black Olivin glaze applied to Clair de lune glaze. The glaze type was created in a collaboration between Kresten Bloch and Nils Thorsson at Royal Copenhagen and was used from 1952.

In the Danish periodical “Klingen”, Axel Salto writes in 1942: “I once found in my garden a spider web down between the Raspberry bushes. It was a meter-wide laced sail, which swayed in the rough September morning, heavy with dew. When the soft wind grabbed hold of the web, a rainbow-coloured fire ran across it, as if it was filtering the first rays of the morning sun, and the spider came rushing, the shrivelled tiny creature, to see if there was anything to do. This diamond-covered fly trap, so simple and naturally formed, so fragile and undaunted, seemed to me to be perfection incarnate, a bold statement in an insignificant darkness of dawn, of nature’s extravagance. I do not recall that any artwork has provided as much resonance in my mind. This web was a demonic thing”.
