Enamel
A shining, vitrified substance employed as an indestructible coating to various articles of taste and utility. The basis of all enamels is a perfectly transparent and fusible glass, which is subsequently rendered either semi-transparent or opaque by admixture with metallic oxides. Engine for Blower.--It is always best to have the blower driven by an independent engine, as by this arrangement the annoyance and consequent loss caused by the breaking-down of any portion of the driving machinery which is common for all purposes is saved, and as these annoyances generally occur when the blast is in full swing the value of an independent engine is wonderfully enhanced. An experimental knowledge of the above facts has resulted in the production of a blower and engine combined, which machine is becoming more popular every day. See BLAST; BLOWER; CUPOLA.
Entablature is that part of an architectural design which surmounts the columns and rests upon the capitals. In this sense the term is applied by engineers to similar parts of machinery-framing wherein such designs are intruded.
