It includes 847 life-size models (representing 780 species and varieties of plants in 164 families) and some 3,000 detail models such as of plant parts and anatomical sections. The collection comprises approximately 4,400 individual glass models representing over 830 plant species.
Vitrification (from Latin vitrum 'glass', via French vitrifier) is the full or partial transformation of a substance into a glass, [1] that is to say, a non-crystalline or amorphous solid. Glasses differ from liquids structurally and glasses possess a higher degree of connectivity with the same Hausdorff dimensionality of bonds as crystals: dim ...
In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive.From a thermodynamic perspective, a substance is inert, or nonlabile, if it is thermodynamically unstable (positive standard Gibbs free energy of formation) yet decomposes at a slow, or negligible rate.
Because a real plant has a life of its own, we can care for it in a way that is not possible for the replica. I can help an acorn become an oak by planting it, but I can neither help a plastic ...
Artificial plants are imitations of natural plants used for commercial or residential decoration. They are sometimes made for scientific purposes (the collection of glass flowers at Harvard University , for example, illustrates the flora of the United States). [ 1 ]
The terms "glass" and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to amorphous materials that undergo a glass transition. [1] Examples of amorphous solids include glasses, metallic glasses, and certain types of plastics and polymers. [2] [3]
Materials that allow the transmission of light waves through them are called optically transparent. Chemically pure (undoped) window glass and clean river or spring water are prime examples of this. Materials that do not allow the transmission of any light wave frequencies are called opaque. Such substances may have a chemical composition which ...
The Guy de Maupassant short story "La Confession" concerns a jealous girl who poisons her older sister's suitor by inserting ground-up glass into cake. [3] The term ground-glass, as it relates to poisoning, is a corruption of grain d'église, the term given by the French in India to the seeds of the Jaquirity or Rosary Pea plant (Abrus ...
