Berg (George, 1730-1775). British organist and harpsichord teacher, composer and chemist. Experiments in Chemistry [so titled on spine], 6 autographed manuscript notebooks bound as one, no place, 1759-1774, containing 672 numbered manuscript receipts recording experiments for glass making, a total of approximatey 250 leaves including some additonal inserted notes on guards and a few loose, some leaves part folding and a few pages inverted, the six notebooks in marbled wrappers with manuscript numerical paper labels to upper covers, the whole bound in modern antique-style half calf over marbled boards with two gilt-lettered spine labels, a little rubbed, 4to (200 x 160mm)Qty: (1)NOTESProvenance: Bought at auction by the vendor's grandfather, Hubert S. Williams-Thomas. Williams-Thomas was interested in all aspects of glass history and proprietor of Stevens and Williams Ltd, which later became Royal Brierley Crystal Ltd, one of the principal manufacturers of crystal glass in the Stourbridge area. George Berg was a London organist and harpsichord teacher. For a brief period (1755-1770) he was also a very productive composer, producing works ranging from operas in Italian to short glees and catches, plus seven collections of keyboard music. However, he also successfully combined chemistry and music, managing to fit experiments on glasses and other ceramics into his busy schedule as composer and performer. This is evident from this laboratory notebook which has been the subject of various articles in modern times: 1) W.A. Campbell, 'Musical Glasses', Chemistry in Britain' vol. 25 (1989), pp. 145-48. 2) Sarah Lowengard, 'George Berg and the SoA [Society of Arts]: interest, improvement, and the meaning of a practical engagement', a paper read to the William Shipley Research Group in 2006. 3) Sarah Lowengard, The Creation of Color in Eighteenth-Century Europe (New York, 2008). 4) Michael Talbot, 'George Berg: An original musical and scientific spirit in Georgian London', The Musical Times, Spring 2019, pp. 3-27. 'All bodies may be chemically considered under three Tribes; Alkalies, Acid, or Neutrals. Alkalis have this essential property, that when mixed or united with Acids, they constitute Neutrals. But a more common mark of an Alkali is that it turns Syrup of Violets green, as an Acid turns it Red, whilst the admixture of a neutral Body does not alter the colour of that Syrup.' George Berg, Experiments in Chemistry Notebook I (no place, no date). 'Experiment 98. 3/4 oz: sand 1 oz: minium 1/4 oz: Borax 1/4 oz: Putty with half of half a Dram of the precipitate of Copper, one Hour in fusion produces an opake composition, the bottom part of a pea green; about the breadth of a goose quil on the top, was of a variegated redish brown thus I suppose the Copper & Minium would not mix, the Copper flew upwards & made the brown part, the bottom part acquired no green but that the minium gave. I believe the blackness on the Top of the Composition Ex: 96 is occasioned as follows the Borax extricates the Marine Acid from the Nitre which is thrown to the surface & there remains being uncapable of vitrifying. I suppose the cause of that redish colour is occasioned as follows: the Minium assists in some manner to calcine the copper yet further than in was before & uniting together produces that effect so I think no minium shall be used with Copper in any form whatever.' Experiments in Chemistry Notebook 2 (n.p. Nov 23 [1762]) 'Expt. 593 Best purple on silver 1 1/2 oz Sand, 1 1/2 oz rough Nitre, 2 1/4 oz minium & 2 drams english Manganese uncalcin'd. I hour in Carters Furnace. This Carter try'd on fine Silver, it is too hard, the silver having melted before the enamel. From this I am led to believe that Manganese prevents the fluxing of the Glass when in a large proportion. Pickavey tried this on Old Sterling Silver, it run very well, is a good purple, but wants to be a little brighter.' Experiments in Chemistry Notebook 6 (n.p. [10 March 1774]) 'The way to find how much Phlogiston is contain'd in any given Body as I learn'd from Mr. More Take any quantity of nitre & melt it in a Crucible & take a like quantity of any Body containing a Phlogiston, & while the Nitre is hot throw on little & little the Phlogistic matter till all is thrown on, then weigh the ashes & as much as it has lost of its original weight so much it contain'd of the Phlogiston.' Experiments in Chemistry 1759-1774 Notebook 2 (insert, n.d.)
