Specification forming part of- Letters Patent No; 111,318, dated January 81, 1&1; Reissue No- 8,888 dated August 19, 1879; application filed March 17, 1879.

To all whom it may concem:

it known that I, Dnoms W. Opium, formerly of the city of Chicago, county of Cook, and State of Illinois, now of the city of Philadclpliia,'State of Pen iisylvania, have inable to resist heat. cold; or moisture, and any tendency to oxidizatiou or decay.

\Vhen I- wish to produce an enamel of a ihite color, I use eighty parts, by'weight, of feldspar; seventy parts of flint or quartz; sixty-five parts of paris-white; flity parts of oxide of zincfifty parts of boracic-acid; twelve parts of kaolin or china-clay, or their chemical equivalents.

For the various colors enumerated below I For black, eightydlve parts; by weight, of feldspar; -seven ty parts of flint or quartz; sixty-five parts of paris-whiteyiltty parts of oxide of zinc; titty-four parts of boracic acid; twelve parts of kaolin or china-clay; two parts of black oxide of manganese; one part of black oxide of cobalt.

For blue, eighty parts, by weight, of feldspar; seventyparts of flint or quartz; sixtyilve parts of perils-white; fifty-two parts of horacic acid; fifty parts of oxide of zinc;

twelve parts of kaolin or china-clay; two parts of black oxide of-c'obalt- For yellow, eighty parts, by weight, of feldspar; seventy parts of flint or quartz; sixtyflye parts of parts-white; flttytwo mm of borac'ic acid; fifty parts of oxide of zinc; twelve parts of kaolin or china'clay; two parts of oxide of uranium.

=Fcjr b, eighty parts, by weight, of feldspa; :mveuttyfparts of liint or quartz ,sixty livej parts'o pads-white; fifty-fire parts of boracic acid; fifty parts of oxide oi sine; twelve parts of kaolin or china-clay; six parts of Brandon mineral paint; one part of potters blue. i

For green, eighty parts, by weight, of feldspar; seventy parts of flint or quartz; sixty fiveparts of paris-white; fifty-two and onehalf parts of boracio acid; fifty parts of ozide. of zinc; sixteen parts of kaolin or chinaclay; two and one-halt parts of oxide of cop per. i Y b For red; eighty parts, by weight, of feldspar; seventy parts of hint or quarts; sixtyfive parts .of, paris-white; fifty-two and onehalf parts of boracic acid! fifty parts of oxide of zinc; eight rtsj'o kaolin or-chinaclay; four parts 0 lime; two and one-half parts of suboxide of copper.

For brown-stone, red sandstone, and va rious other colors, variable proportions 'of these several mixtures may be used,as desired, and the proportions may also be varied.

It is to be observed that the various proportions of the diflerent ingredients maybe slightly changed, as experience may dictate, I

in consequence of lhe variety in' the constituentpsrts' of various ,clsy's, some clays having more oxide of iron and more lime than other clays. The method of usin thesewurlons elements to produce the dos results is to combine.

all"the several ingredients for any special -oolor together in a crucible or retort and cal cine them together not separately if the -beet results are dcsi Then reduce the mass,

in a mill or under the mullet: or pestle, with water to about the consistency of cream, or tosuch-a degree as to be easilyand smoothly spread over the surface to be treated. The

articles are then coated, either by brushes or immersion, and then raised to a snfllcient temture in suitable well-known appliances to use the enameling compound.

I claim as my invention- 1. A white enamcling compound for building-bricks and other articles produced from clay, and for iron and other-metallic articles, compounded of the ingredients substantially in the proportions and manner described, and applied substantially as set forth.

2. Coloredeuamelin'g compounds for buildiuz-bricks or other articles produced flom dients substantially iii the prbportione-hnd okay, and for iron and other metallic 311M188, manner de'soribed, and applied substantially eonqxnmdml of the ingredients substantially as set: forth; in the proportions and manner described, and

applied substantially as set forth. 3y

3. As e new article of manufacture, bricks, Witnesses:
