Tincal, also known as sodium borate or borax is a porous mineral consisting of soft colorless crystals that dissolve easily in water. Among its many possible applications, it’s used in powder form during the process of melting metal or diluted, as a flux, during welding, acting as a supporting element of this process: it slows the oxidation of the metal and helps the solder to run along the joint of the two parts that you want to connect.

Being a word that sounds familiar to most jewelers, it also works here as an invitation to the rest of the public to come to know and interact with this fascinating universe.


Tincal lab opened its doors in June 2015 on a second floor space at Rua de Cedofeita, in downtown Porto. In the end of 2018 it found a new home in the heart of Porto Art District: visit us now at Centro Comercial Bombarda, shop 25.


Tincal lab is a contemporary jewelry work+shop space founded by Portuguese jeweler Ana Pina. As a showroom of the brand you can contact directly with the artist, see her work live and get to know the working space where the jewels are created.

Under the motto curating and experimenting in contemporary jewelry, we regularly launch collaborations and events that help to promote this amazing creative area, such as workshops with invited jewelers, individual and collective exhibitions, featuring works by local and international artists.

We also have workbenches available to be occupied in a monthly or occasional basis by fellow colleagues that are looking for a specialised, inspiring and central working space. For more information feel free to contact us.



Ana Pina was born in 1980, in Porto, Portugal, city where she studied, still lives and works.

She graduates in architecture (FAUP, 2004) and works in an office for a few years, until she founds her passion for contemporary jewelry and decides to work as a jeweler full time. Her background in this area includes a workshop in school Contacto Directo and the professional course in school Engenho e Arte, besides some specific complementary workshops.


She develops her personal jewelry brand since 2012 and Tincal lab is since 2015 the workshop and showroom of the brand, exhibition space, meeting point with colleagues, friends and customers.


In her work she combines her background in architecture with traditional jewelry techniques and contemporary concepts of design in the creation of jewels with a strong abstract and geometric inspiration, in search of a modern, versatile and feminine style.

Unique pieces or limited collections combine elements of a common vocabulary in a game of contrasts and textures, geometric relations and asymmetries, as if they were letters building words inserted in a bigger text.
