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.
  

Angelica Kauffman, RA (1741 - 1807)

was a Swiss-born Austrian Neoclassical painter who had a successful career in London and Rome. Though born as "Kauffmann", Kauffman is the preferred spelling of her name in English; it is the form she herself used most in signing her correspondence, documents and paintings.

While Kauffman produced many types of art, she identified herself primarily as a history painter, an unusual designation for a woman artist in the 18th century. History painting, was considered the most elite and lucrative category in academic painting during this time period. Under the direction of Sir Joshua Reynolds, the Royal Academy made a strong effort to promote history painting to a native audience who were more interested in commissioning and buying portraits and landscapes.

Despite the popularity that Kauffman enjoyed in British society and her success as an artist, she was disappointed by the relative apathy that the British had towards history painting. Ultimately she left Britain for the continent, where history painting was better established, held in higher esteem and patronized.

The works of Angelica Kauffman have retained their reputation. By 1911, rooms decorated with her work were still to be seen in various quarters. At Hampton Court was a portrait of the duchess of Brunswick; in the National Portrait Gallery, a self-portrait. There were other pictures by her at Paris, at Dresden, in the Hermitage at St Petersburg, in the Alte Pinakothek atMunich, in Kadriorg Palace, Tallinn (Estonia).

Satinwood

is a hard and durable wood with a satinlike sheen, much used in cabinetmaking, especially in marquetry. It comes from two tropical trees of the family Rutaceae (rue family). East Indian or Ceylon satinwood is the yellowish or dark-brown heartwood of Chloroxylon swietenia.

The lustrous, fine-grained, usually figured wood is used for furniture, cabinetwork, veneers, and backs of brushes. West Indian satinwood, sometimes called yellow wood, is considered superior. It is the golden yellow, lustrous, even-grained wood found in the Florida Keys and the West Indies.

It has long been valued for furniture. It is also used for musical instruments, veneers, and other purposes. Satinwood is classified in the division Magnoliophyta, class Magnoliopsida, order Sapindales, family Rutaceae.
