Description
The "Hyperboloid" jewellery box, with a difficult crafting, has its origin on a short story. The author studied this surface analytically, at the Infinitesimal Calculus class at Universidade do Porto and then he thought of giving it spatial reality, thus establishing the bridge between practice and theory. Due to this, he called the piece "Hyperboloid".
This jewellery box is composed by two elements, the interior compartment and the lid, and is crafted out of noble woods, richly decorated with ebony and edged with mahogany. Geometrically, the inner compartment received the shape of a hollow conical frustum, with a lower circular base. It is veneered in walnut root and lined on the inside with green velvet. The lid, is veneered in walnut root and trimmed with ebony/buxum, crafted in the shape of a frustum of a hyperboloid of revolution of one sheet, topped by a circular base.

Internal Notes
Este guarda-joias foi construído na década dos anos 90, do século 20, com madeiras nobres, ricamente decorada a ébano e orlada com mogno. O guarda-joias “Hiperboloide” de difícil execução manual foi baseado numa pequena história. O autor estudou analiticamente esta superfície, na cadeira de Cálculo Infinitesimal na Faculdade de Ciências da Universidade do Porto e pensou, então, dar-lhe realidade espacial, estabelecendo assim a ponte entre a prática e a teoria. Devido a este facto, o autor designou-a por “Hiperboloide”. A peça é essencialmente decorativa, no entanto, o seu cariz é utilitário, servindo portanto, como guarda-joias. O guarda-joias “Hiperboloide” faz parte integrante da coleção dos 81 guarda-joias, doada à Universidade de Aveiro pelo Sr. Eng.º Joaquim Domingos Capela em Dezembro de 2013.
