Hanna and Joanna met at Philadelphia's University City Arts League pottery studio in 2019. Hanna had just started her second year of graduate school at the University of Pennsylvania, and the catalytic converter had just been stolen from Joanna’s 2003 Honda CRV.

Their friendship bloomed at the pottery studio, and when the arts league was forced to temporarily close in the spring of 2020, they bonded over their shared loves of crocheting, baking and Irish detective novels.

All pieces are hand made by Joanna and Hanna on the pottery wheel from high-fire ceramic clay. Home wares (unless otherwise noted) are food, microwave and dishwasher safe.

Stonewær porcelain jewelry is made by hand and gets its signature shine from special third kiln firing after applying a metallic luster "overglaze."
