VACUUM FILLED SAMPLING DEVICE FOR MOLTEN METAL Abstract of the Disclosure A device for sampling heats of molten metal adapted to be connected to a source of vacuum to suck a sample of the molten metal into a refractory sample forming cylinder and attached disc mold chamber through the open end of the cylinder, the open end of the cylinder being closed and sealed prior to the sampling step by a metallic cap which will melt in the molten metal heat, the metal cap being hermetically sealed to the end of the cylinder by a hardened plastic applied as a liquid to the cap and contiguous portion of the cylinder, the plastic coating having a thickness and composition such that any surface flux material adhering to the sampling device as it is thrust into the heat will be removed completely from prox- imity to the lower end of the cylinder by the act of decomposi- tion of the plastic.
