Composed mostly of talc, soapstone is a very soft stone that marks slate and metal easily, yet doesn’t leave a chalky mess on your hands. Welders and fabricators use soapstone as a marker due to its resistance to heat and because it won’t contaminate welds, but it’s useful for those who work with wood and fabric as well.

Use & Care

Write on slate or metal, can even be used on heated metal. Wipe off with a damp cloth or sponge.

Production & Design

Kristy Hadeka is the fourth generation of a slate mining concern; her great-grandfather bought the family's first slate quarry and they have since expanded to several more dotted across the Vermont and New York Slate Valley, a unique geological region spanning the two states that has a long history in slate production. Her father, uncles, and older brother all work in slate production, primarily in the manufacture of roofing tiles. And as a child, she longed to work in the quarries too.

In 2009, Hadeka, a Parsons graduate student, and her partner, web developer and graphic designer Sean Tice, hit upon an idea while visiting her family's slate quarry in upstate New York. Inspired by the handcrafted DIY movement that was picking up momentum in Brooklyn, where they live, they brought back some pieces of slate to use at home and to give to friends. The response was so overwhelmingly positive that the couple decided to produce a line of slate products. And Hadeka loves being able to work with her father every day.

Hadeka and Tice regularly travel to the quarry to personally select their favorite pieces of slate. Some of the slate is new, while other pieces are repurposed. They cut and clean the stones at their studio in Red Hook, Brooklyn.
