Read the guide →The right tools make casting with Jesmonite faster, cleaner and far more consistent. In this category you will find the accessories we reach for every day in our own studio: mixing cups and beakers, digital scales for accurate powder-to-liquid ratios, spatulas and stirrers, sanding materials for smoothing edges, and sealers that protect your finished pieces against water and stains.
Accurate measuring matters. Jesmonite is mixed by weight, and a reliable scale is the difference between a flawless cast and a frustrating one. Once your piece has demoulded, which takes only 20 to 40 minutes, a light sanding and a coat of sealer give it a professional, retail-ready finish. Sealing is especially worthwhile for coasters, trays and bathroom pieces that will see daily use.
