Best Clay Slip and Magic Water
As an Amazon Associate I earn from qualifying purchases.
Slip and magic water are the two workhorse solutions for joining clay, and knowing when to use each prevents the heartbreak of handles popping off in the kiln. Slip is simply clay suspended in water, best for filling gaps and attaching pieces at similar moisture levels, while magic water uses sodium silicate and soda ash to partially dissolve the clay surface, creating stronger bonds on stiffer or leather-hard joins. For home potters, a small investment in proper joining materials eliminates the most common cause of cracked attachments. This guide compares premixed slips, magic water ingredients and recipes, and commercial joining products, and explains which option suits handles, sculptural joins, and slip trailing decoration so your attachments survive drying and firing.
