Challenge 2022 Jewelry and Literature


Two worlds

Look, these are two worlds:

It’s not possible to throw water

to mathematics. 

Gonçalo M. Tavares, “1”, Relógio D’Água, p 73 

(free translation)


How can two worlds so seemingly different meet? Literature is born from the field of ideas, jewelry materializes in a close relationship with the human body. Both require technique, both are art and produce emotions in those who create and admire them. Their expressions, however, couldn’t be more distinct and diverse.

With literature we can refer to texts in prose or verse, to novels, short stories, novellas and plays, fiction and nonfiction, epics, odes and sonnets. We rhyme or we don't rhyme, while we multiply stanzas, verses and figures of speech. We invent plots and characters, describe reality and build imaginary worlds. We convey messages, we make people think - while we think ourselves.

We write by hand, on the typewriter, on the computer. With paper and pencil, permanent ink or accompanied by the rhythm of a keyboard. We write with gestures, with letters, words and sentences - with different alphabets. We scratch and tear, revise and rewrite, keep in a drawer, erase - or publish. We dictate, make declarations of love - and of hate.

But we also read: books, manuscripts, on a digital screen. We learn, interpret, underline, quote, declaim.

For this year's Challenge, we invite you to be inspired by the vast and rich world of literature: a favorite author, a remarkable book, an unforgettable character, a support or writing instrument that you consider indispensable.

Jewelry and Literature. How do these two worlds meet?

From the simple letter to the masterpiece, the freedom to answer this question is in the hands of the artists. Happy readings!

The artist shouldn’t make them public before the opening date and will not sell them in parallel during the period of exclusive use by the organization. The possibility and conditions of posterior reproduction and sale remain at the artist's discretion.

On the other hand, it’s encouraged the promotion of the event (with due reference), even during the creation period, including sharing of images related to the work process and sources of inspiration, for example. In this case we ask the artists to tag Tincal lab (@tincallab) in the publications and use the hashtags #tincallab and #tincallabchallenge2022.



Application is free - in case the artist is selected, the formalization of the registration implies the acceptance of the terms of participation and the payment of a participation fee of 30€.

All payments should be made by bank transfer (for payments in euros) or Paypal. The selected candidates will receive further information.



The pieces must be delivered in time to the organization (in person or sent by post). If they arrive after September 30th it is not possible to guarantee that the artist will be included in the catalog.

Until this date, after the execution of the pieces and for the purposes of the catalog and online shop, it will be requested detailed information about the pieces:

- inspirational text (written in the third people or in abstract sense, maximum 100 words), title, typology, materials and dimensions

- high resolution quality photos (white background, 300dpi, minimum size 2000x2000px).

The organization reserves the right to photograph the pieces if it deems it more appropriate. According to the requirements of the catalog and depending on the characteristics of the pieces, it’s possible that only one is selected by the organization for publication.


Shipping costs (of sending the pieces and its eventual return), will be at the artists expense.

Please be advised that shipments made to Portugal from countries outside the European Union may be subject to customs verification - Tincal lab can not be responsible for the delay and payment of fees that may result of it. In these cases, the use of non-precious metals is strongly advised.

Tincal lab shall not be liable for any loss or damage incurred during transportation, assuming responsibility for the pieces during the period of time they are in the gallery.

Artists should contact the organization before shipping the pieces.



Exhibition takes place at Tincal lab from November 12th to December 31st of 2022. After this date, the pieces remain available for sale at Tincal lab for the minimum period of 6 months, after which they will be returned or will continue to be sold by the organization, depending on what’s agreed between the parties.

They will also be sold, all or in part, in the online shop ( during the same period.

The photographs used in the online shop will be the same taken for the catalog - to ensure that all the pieces will later be included in the online shop, it’s advisable to send quality photographs by email for this purpose.



Pieces will be sent on a consignment basis and the maximum retail price is of 150€. The commission of Tincal lab is of 50% (example: in a piece with final price of 150€ the artist price is 75€).

The establishment of a maximum price for the pieces shouldn’t be seen as a limitation, but rather as a way to raise the bar of the challenge, helping demystify contemporary jewelry to the public and giving everyone the opportunity to purchase a piece.



There is the hypothesis of a traveling exhibition, if proposals appear. Selected artists will be contacted in this case.

The aim is to create an event with its own unifying image, but ensuring the individuality of each artist, so it’s encouraged the delivery of the pieces in the individual packaging of the brand, to make the authorship of the piece clear when it reaches the customer.

We aim, above all, that this concept will serve to inspire us to create and to bring the world of contemporary jewelry to a more comprehensive and relevant audience.


Good work to everyone!
