Ceramicist

A shared vision, a shared inspiration

Diogo and Isac share childhood ties to Angola which has shaped their vision of ceramics
They reuse all their clay, so that no resources are wasted
Their REVERSIBOWL creation is an iconic, dual-use design, working as both a bowl and a sculpture

Isac Coimbra and Diogo Ferreira have made a ceramic workshop out of their home in Lisbon. At GRAU° Cerâmica, they explore how ceramics relate to their surroundings, shaped by Isac and Diogo's backgrounds in architecture and visual culture. “Our training gives us a keen sense of spatial awareness, both in relation to the pieces themselves and the settings they inhabit,” they say. In some works, jute and rope add texture while visually extending the form—emphasising verticality or creating connections. Often described as 'modern tribal', the duo's aesthetic is rooted in childhood memories and family ties to Angola. “We grew up surrounded by traditional African crafts,” they explain. “Our interpretation, using clay, results in minimalist, geometric pieces.” They reuse all their clay, repurposing broken pieces into new collections to ensure nothing goes to waste.

Interview

What colours and finishes define your style?: We combine clays in black, white and terracotta, both glazed and unglazed. Minimalist white stoneware enhances contrast, while high-fired black clay deepens silhouettes. Warm terracotta tones, from rich oranges to deep reds, bring a natural warmth to any space.
Which piece best represents your joint creativity?: Our REVERSIBOWL is one of the most iconic pieces, designed for dual use when inverted. It captures shadows beautifully and functions as a fruit bowl or as a design object. It embodies both our aesthetic and structural backgrounds while allowing the user to define its purpose.
Do you offer custom ceramic designs?: Custom projects have become a significant part of our work, allowing us to push our creativity. Each client brings a new challenge and forces us to step outside our comfort zone, making every collaboration an exciting opportunity.
What do you hope buyers experience with your work?: We aim to bring a new sensitivity to a space through our pieces, evoking curiosity and joy. Our ceramics are designed to be more than objects – they are meant to engage, inspire and create a deeper connection with those who appreciate and interact with them.
