Page 6 - ... sensitive pyrometer. The two great advantages resulting from the use of the pyrometer, which are at once evident, are: (1) Once the proper method of working a particular product has been found, this operation can be indefinitely repeated, thus rendering possible the exact duplication of products. (2) The reproduction of any particular product is no longer locked up in the experience of a few workers, but becomes a matter of permanent record, which may be consulted at any time. In this connection...
