A molten metal sampler which employs a jacket of sand-sodium silicate mix around the metal mold halves to prevent molten metal splash on the exterior of the mold halves, prevent leakage of molten metal from the mold halves and provide good venting. The sand is molded around the mold halves and, in one embodiment, the protective cardboard sleeve used for connecting the sampler to a manipulating rod serves as the mold for the sand-cement mix. |
