SOME ENGINEERING ASPECTS REGARDING
OSHIBANA ART
The pressed flower art, Oshibana, was developed by japans samurai
centuries ago. This art found followers in Romania, some of them being
Oshibana Maestro Artist. Inspired by them we found that some basic
engineering aspects are beyond the success in the flower pressing process.
The authors of this paper aim to practice these engineering aspects on the
vegetal material to obtain suitable Oshibana parts. We use petals from the
following flowers: yellow rose (Rosa L.), red carnation (Dianthus Caryophyllus),
and violet crocus (Crocus Vernus). The resulted pressed petals were
investigated with transmitted light optical microscope. The petals fibber network
was observed as well as the pigment alveoli. The petal cohesion under
pressure is assured by the cellulose fibres meanwhile the intracellular liquid is
absorbed by the press paper pages, finally the petal cells become flat and dry.
The pigment alveoli were distinct observed for all samples. Their diameter is
significantly increased under pressure ranging from 30 – 40 μm. The flattening
tendency is prone at Crocus and Dianthus and less intense at the Rose petal.
