Menno Jonker, Microcosmos, 1998, discussed and depicted in Menno Jonker's monograph 'Deep Sea' on page 7. Titus M. Eliens says about this, 'They are sturdy organic gods, with a stone-like skin that enclose the container form. These unique pieces not only show that Jonker is not only interested in glass, but also in the contrasting material. In addition, they show that the reflections in the glass, which made him decide to choose this material some years before, are now deliberately ignored and even eliminated by him.' Also depicted in the book 'Solid perceptions Menno Jonker' by Dan Klein, on page 133 with color photo.
