British Glass Master and Mixer
BEING LEAVES FROM THE MIXING BOOK OF SEVERAL EXPERTS IN THE FLINT GLASS TRADE
CONTAINING UP-TO-DATE RECIPES AND VALUABLE INFORMATION AS TO CRYSTAL, DEMI-CRYSTAL AND COLOURED GLASS JN ITS MANY VARIETIES
IT CONTAINS THE RECIPES FOR CHEAP METAL SUITED TO PRESSING, BLOWING, ETC., AS WELL AS THE MOST COSTLY CRYSTAL AND Ruey
BRITISH MANUFACTURERS HAVE KEPT UP THE QUALITY OF THIS GLASS FROM THE ARRIVALS OF THE VENETIANS TO HUNGRY HILL, STOURBRIDGE, UP TO THE PRESENT TIME
THE BOOK ALSO CONTAINS REMARKS AS TO THE RESULT OF THE METAL AS IT LEFT·THE POTS BY THE RESPECTIVE METAL MIXERS, TAKEN FROM THEIR OWN MEMORANDA UPON THE ORIGINALS

NOTES BY THE COMPILER.
Repeats are given of more than one recipe, so that the mixer may acquaint himself how to use up his cullet or to vary his mixture to suit his requirements.
The costs given of t he cheap metal is based on the cost of materials some year or two ago, but it is approximately correct at the present time.
The sand used in most of the recipes is French (Fontenbleu), except in some old forms, when it was Isle of Wight; and the soda supplied by a Northwich firm.
Colouring should generally be about half put into the batch and the other half reserved until the long proof has been taken off, when it can be added to or diminished to suit furnace or the weather.
The sand in the crystal should be washed and calcined. In the commoner metal it is used as it arrives ; still the quality is greatly improved by the first process.
Many of the finest colours containing cryolite should be worked immediately it is plain.
In using brass, it is necessary to insure correctness that it should always be the same. Brass differs in its composition.
The greatest care should be taken in the purity of all material, and the greatest ca1·e should be taken that everything is clean and free from dust and dirt.
In all these colourings allowance must be made throughout this book for the state of the furnace, weather, purity of sand and mater(al, etc.

"This mixture turned immediately it was put into the lear. Fill the pot for ruby a little at a time, and watch that it does not ferment. It does not require above twenty hours to fine ; and mind the pot does not get too hot. When ct is worked into lumps, put it into the !ear with some fine ashes. Keep it turned often, and when a dark ruby get it down the !ear ; if it be not all dark, it will right itself in the plating. The metal from the pot should be a light straw colour." 4

The chapters on grease and solidified oils, etc., are excellent."-T/te lronmonger. "In its ninety-six pages this little work contains a wealth of information; it is written without waste of words on theoretical matters, and contains numerous formulas for a great variety of compounds for the most varied lubricants.

The book is illustrated throughout and is admirably indexed and arranged."-lroti and Steel T rades f ournal. " It is of the utmost importance to have reliable information on the various so-called infal lible anti-corrosive paints which Hood the market, and the large experience which evidently had been gained by the author in relation to the subject enables him to present in the work und er notice an important contribution towards the solution of the problem involved, which is bound to prove extremely ser\·iceable not only to paint manufacturers, but to engineers, contractors, iron-founders, ship-builders and others. The subjt:ct is thoroughly dealt with in all its various phases, and the vast fund of information afforded not only regarding rust for mation and its prevention, but in reference to paints, varnishes, oils and pigments generall y, should prove very valuable to the large class interested, while additional importance is given to the book by the numerous illustrations which were prepared by the author in the course of a series of personal experiments on the formation of rust."-814-ilders' Repo1·te1. 7 LUBRICATING OILS, FATS AND GREASES: Their Origin, Preparation, Properties, Uses and Analyses.

It is pleasing to note that the practical part is not crowded out with purely 'practical recipes'. A few typical examples arc given, and the rest is left to the common sense and judgment of the printer or works' chemist. Another pleasing feature is the accounts given here and there of the author's own researches on the subject.

The primary aim of the publishers is to provide scientific text-books which will be helpful to those who arc either actively engaged in the practice of the arts in question, or who are studying with that immediate end in view .... Mr. Paterson speaks with that assured knowledge of an expert, and in the present volume, as in that which he has already contributed to the same series, he sets forth the true foundation of the art of colouring in a manner at once comprehensive and judicious . . . . For dyers, calico printers and colourists in general, whose desire it is to work with accuracy in their respective branches, the treatise will prove an invaluable guide-book, provided the principles and methods it describes arc studied with intelligence and care.
