A Satisfactory Luting MixtureCategory: 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. Next: Gas Consumption For Carburizing Previous: Using Illuminating Gas
