Gonçalo Alves is a hardwood (from the Portuguese name, Gonçalo Alves). It is sometimes referred to as tigerwood — a name that underscore the wood’s often dramatic, contrasting color scheme.
While the sapwood is very light in color, the heartwood is a sombre brown, with dark streaks that give it a unique look. The wood’s color deepens with exposure and age and even the plainer-looking wood has a natural luster.
Two species are usually listed as sources for gonçalo alves: Astronium fraxinifolium and Astronium graveolens, although other species in the genus may yield similar wood; the amount of striping that is present may vary.
In the high tropical forests of Central and South America, well-drained soils furnish nutrients for a variety of dense, durable hardwoods sought for maritime use, heavyconstruction, and furniture. The Spanish began harvesting in Latin American forests in the early 1500s to provide timber for boatbuilding and repair. By the early 1900s, however, steel ships had replaced wooden ones, and the interest in tropical forests by both Europeans and Americans shifted to appearance-grade woods for furniture.
Although history fails to provide us with a shopping list of species from either harvest period, it's probable that the wood we know today as goncalo alves has always been sought. That's because goncalo alves, considered one of the most beautiful of tropical woods, has a tough reputation, too. Strong and durable, it's used for construction in its homeland and secondarily for fine furniture. Woodworkers elsewhere treasure the wood for decorative items and veneer accents.
Empire style,
is an early-19th-century design movement in architecture, furniture, other decorative arts, and the visual arts followed in Europe and America until around 1830.
The style originated in and takes its name from the rule of Napoleon I in the First French Empire, where it was intended to idealize Napoleon's leadership and the French state. The style corresponds to the Biedermeier style in the German-speaking lands, Federal style in the United States and to the Regency style in Britain. The previous style was called Louis XVI style, in France.
The Empire style was based on aspects of the Roman Empire. It is the second phase of neoclassicism which is also called "Directoire", after a goverment system.
Furniture typically had symbols and ornaments borrowed from the glorious ancient Greek and Roman empires.
The furniture was made from heavy woods such as ebony, imported from the colonies, with dark finishes often with decorative bronze mounts. Marble tops were popular as were Egyptian motifs like sphinxes, griffins, urns and eagles and the Napoleonic symbols, the eagle, the bee, the initials "I" and a large "N."
Gilded bronze (ormolu) details displayed a high level of craftsmanship.
Serpentine Marble / Verde Antico
Serpentine is a major rock forming mineral and is found as a constituent in many metamorphic and weathered igneous rocks. Serpentine’s structure is composed of layers of silicate tetrahedrons linked into sheets; this structure is what gives it its high flexural strength rating.
Verde Antico is the commercial name for the serpentine “marble” derived from highly sheared ultramafic rocks that have been rewelded and metasomatized by the process of serpentinization. These ultramafic bodies are now recognized as segments of ancient oceanic crust that became part of the eastern North American continent during the Taconian orogeny. This is considered to be middle Ordovician in age, around 450 million years ago.
More deformation and metamorphism took place during the Acadian orogeny around 360 million years ago.
