Main essence:
Beech
It is a semi-hard wood which, unfortunately, is easily wormed, therefore it is considered poor. Due to its light but variegated shades, from blond to reddish, it was nevertheless appreciated by French cabinetmakers. It was mainly used for furniture structures or, as an alternative to walnut, by provincial English furniture makers for popular works, mostly in the 1700s. The noblest use is due to Thonèt, who applied the steam bending of the beech in the making of the furniture, in particular for the chairs that took his name.
Walnut
Walnut wood comes from the plant whose botanical name is juglans regia , probably originally from the East but very common in Europe. Light or dark brown in color, it is a hard wood with a beautiful grain, widely used in antique furniture. It was the main essence in Italy throughout the Renaissance and later had a good diffusion in Europe, especially in England, until the advent of mahogany. It was used for solid wood furniture and sometimes carvings and inlays, its only big limitation is that it suffers a lot from woodworm. In France it was widely used more than anything else in the provinces. In the second half of the eighteenth century its use decreased significantly because mahogany and other exotic woods were preferred.
Poplar
Essence considered "poor", it is a white wood, with yellowish or greyish shades, light and tender, which is easily damaged. It is used for rustic furniture or in the construction of furniture. The most valuable use it has had in the history of furniture is in Germany, in the 19th century, for veneers and inlays in the Biedermeier period.
