A Satisfactory Luting Mixture






Category: CASE-HARDENING OR SURFACE-CARBURIZING

A mixture of fireclay and sand will be found very satisfactory
for closing up the boxes, and by observing the appearance of the
work when taken out we can gage the suitability of the methods
employed, for unless the boxes are carefully sealed the work is
generally covered with dark scales, while if properly done the
articles will be of a light gray.

By observing the above recommendations reliable results can be obtained,
and we can expect uniform results after quenching.
