River stones are visually compelling. Added, in place of lava rock, as a full surface topping they change the character of each fire pit. The repeating forms and varied tones of the stones provide an interesting, textured surface that stands in contrast to the smooth, seamless concrete of our vessels. Castings of actual river rocks, our lightweight refractory concrete fire stones look and feel like the real thing while being stable when exposed to high heats. Each set consists of four colors in a variety of shapes and sizes and will not split, spall or fracture. Our fire stones are made exclusively for Solus, by hand in Canada.
