Martti Jewelry’s pieces are made with clay sourced near our home, in the State of Minas Gerais, Brazil, where multiple colors and consistencies of clay can be found. Once the clay is chosen for a particular design, the crafting process is long and entirely handmade by our Ceramic Artist, Marcia Campetti.
Each piece may take 5 to 10 days to be completed, and each one is unique because it is the irreproducible result of a number of variants. Some of these are the organic manual shaping, the local temperature and air humidity of when it's created, where it’s placed inside the over for the firing process, among others.
One batch is never the same as another, which is why all our designs are limited collections.We hope you enjoy learning about the step-by-step behind our process of creating precious jewelry from clay!
Before being shaped, clay must be prepared. Wedging is the manual technique we use to ensure the moisture is even through the clay body and that all air trapped within is removed.
Once a clay body has been wedged, each piece is shaped using mainly 2 techniques: round shapes are thrown in the pottery wheel, while the more organic and free shapes are manually sculpted.
No molds are used in our shaping process.
Pieces are then stored to naturally dry, which can take 2 to 6 days. At the leather-hard stage (15% of moisture), they are trimmed by hand for a refined look and feel.
Martti’s signature and wholes for the metals are also applied at this stage.
This is the first high-temperature heating of the pieces. It is done to vitrify, which means to bring them to a point that they can have a glaze adhere to the surface.
Some designs feature a layer of gold or platinum luster, which is manually applied with a brush at this stage and then taken to the kiln once again for a third and final firing (4 hours).
With the ceramic pieces ready, it’s time to assemble them with its metal parts that have been previously welded in-house to match the desired design. Our metals are also locally sourced from family-owned businesses. We exclusively use 18 ct gold and rhodium plated over brass, nickel-free and hypoallergenic.
