TAkc of fine Lead 30 pound, of fine Tin 33 pound. Calcine them toge¬ther in a Kil,and fertc them, Boil this Calx a little n clean water in clean earthen veffels, tike it from the fire and de¬cant off the water by inelination, which will carry with it the finer part of the Calx, put frefh water on the remainder, tb.cn boil and decant as before , repeat this as long as the water carries eft' any Calx.
Recal-Recalcine the grofs rem lining Calx,& then draw off again the more fubtile parts, as before. Then evaporate the waters which carried off the finer Calx at a gentle fire, efpecially at the laft, that theCilx miv not be wafted, which will remain at the bot¬tome much finer than the Ordinary. Take then of this fine Cilx, of Crylhl Fritt made with Tarfo, ground and forced fine, of each 50 pound , of white fait of Tartar eight ounces, powder, ferce and mix them well : Then put this fluff into a new earthen pot baked , giving it a fire for ten hours, then powder it and keep it in a dry covered place. Of this fluff are nude all the Enamels of whatfoever colours. This fhall be call’d the Huff for E 3am els.
To avoid our Authors repetitions obferve
1. The pots wherein Enamels are made mud be glafed with white glafs and bear the fire.
2. Mix and incorporate well the colours and ftutf for Enamels.
3. When the Enamel is refined, and the colour good, and well incorporated, take it from the fire with a pair ot tonges for the Goldfmiths ufc.
4. The way to make Enamels is this;
L 3 powder,/ powder, grind, and serce well the colours, and mix them first well one with another, and then with the stuff for Enamels, then set them in pots in the furnace, when they are all melted and incorporated cast them into water, and when dry set them in the furnace again to melt (which they soon do) make a proof, and if the colour be too high, take out some of it and add more of the stuff for Enamels, and if too light add more of the colour at pleasure to your con¬
tent, then take it out of the furnace.

rate, make a proof with your eye that you may know by the eye when the colours are good, as I have always done, becaufe fometimes tnc powders colour more and fometimes Jefs. Thus I did at P/fa, and by mine eye without weights coloured all forts of Glafs.
