A Satisfactory Luting Mixture





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.
