Graphite Crystal Structural Model (often called a "molecular model")
Handmade in the U.S.
Ebonized and varnished 1-inch (2.5 cm) hardwood balls with stainless steel rods
Dimensions: Height 9.25 inches (23 cm), Width 10 inches (25.4 cm), Depth 7.5 inches (19 cm)
This handmade model is an accurate representation of the atomic structure of graphite at a scale of 1 Å = 30 mm (1.18 inches). (Magnified 300 million times.)
Physical models have been used by chemists for almost two centuries for three-dimensional representation of atomic arrangements in molecules and crystals. Their use has declined in recent decades due to advancements in computer graphics, but their importance remains in providing tactile intuition, historical connection, and inspiration.
