In general, cover-coat slips for sheet iron are milled to give a residue of from 4 to 9% on a 200-mesh sieve. The opinion was formed that finer milling results in tearing because of results secured on the box-type rather than the continuous furnace.

The results are presented on work done to increase the opacity of enamels by mill practice and mill additions, such as milling to abnormal fineness, addition of opacifiers at the end of the milling period, the effect of the addition of feldspar, and
