1848 February. 'Mr. Charles Hancock, of Brompton, has obtained several patents for manufacturing it (gutta percha) into various articles, and that gentleman, in connexion with his brother, Mr. Walter Hancock, established a manufactory Stratford, 1845, and in the subsequent year other and more extensive premises were taken, situate in Wharf-road, City-road, London. Ultimately a company was formed, consisting of several gentlemen of wealth and enterprise, including Ernest Bunsen, Esq. of Upton Grove, in this county, (son Chevalier Hansen) and of the extent and operations of the company some conjecture may be formed from the subjoined statement. At the Stratford, as well as the City-road works, several powerful steam engines are in operation, and two have recently been added. About 80 persons are employed in the former place, in the manufacture of lathe bands and a solution for adhering percha soles boots and shoes. These works an: ostensibly under the management of Mr. Walter Hancock and Mr. E. Moore. The City-road establishment is the principal depot, where between two and three hundred hands are employed. The manager is J. Stathan (Statham?), Esq. of the firm of Statham and Bates, of Manchester. The experimental managers are Mr. C. Hancock, Mr. W. Hancock, and Mr. Bewley. The superintendent of the sole department Mr. Joseph Watson. The whole of the gentlemen selected for the above departments are well known in the scientific commercial world. The average sum paid each week for wages at the two establishments is about one thousand pounds, and the present returns, from the sale of articles, at least £500,000 per annum. The works are daily inspected persons of rank and distinction, and among the recent visitors we may mention the Rajah of Sarawak, Mr. Brooke. The gutta percha is a good substitute for leather, and has been long used for lathe bands. Most tin mill owners the manufacturing districts have substituted them in lieu of the old leather lathe bands; large numbers are weekly sent to Manchester, Liverpool, Leeds, &c, well as Ireland and Scotland. Some oi the other articles for which inapplicable, are outer soles for boots and shoes, picture frames, walking-sticks, inkstands, door-handles, chess men, some surgical instruments, watch-guards, whips, flutes, floor-cloths, harness for horses, sword and knive handles, it is also suitable for obtaining fine impressions from coins, and is manufactured into a fine thicking used by milliners for lining ladies' dresses and bonnets, in lieu of oiled silk, also extensively used in hospitals for bandages, &c. Large quantities of gutta percha articles arc exported to Germany, Prussia, America, Holland, Belgium, and France; and the increasing demand for them has led the company to take other extensive premises in the Wharf-road, City-road, the occupation of the Patent Wood Fuel Company, and should only tithe portion of the articles now manufactured be brought into general use, gutta percha will form, no distant period, one of the most important items British commerce'

Query - is this the same person as above?
CHARLES HANCOCK was born about the year 1795; the exact date cannot now be ascertained, nor are there available any particulars concerning his antecedents, belongings and place of birth.
The exhibition of a picture at the Royal Academy in 1819 gives us our first clue; that year discovers Hancock, then a young man of about 24 years, residing at 55, St. James's Street.
He won this first success with a portrait of "Mr. J. Hancock," a near relation, no doubt, of his own.
His name does not occur in the Royal Academy catalogue of the following year; but at the exhibition of 1821 we find him represented by "The Broken Teapot," a title which suggests that his artistic tastes took first a direction domestic rather than sporting.
At this latter date he was residing at Marlborough, in Wiltshire, and thenceforward until the year 1830 he would seem to have had no fixed abode: he dwelt sometimes at Marlborough, sometimes at Reading, and sometimes at High Wycombe, his London address being given as "Messrs. Tattersall's, Grosvenor Place," through which firm his dwelling-place was always to be discovered.
Between the years 1819 and 1847 he exhibited at the Royal Academy twenty-three works; and though these no doubt include many of his best efforts, it is noteworthy that the portraits of racehorses (a class of work which formed one of his specialities) are not represented among them.
He did not confine his exhibits to the Royal Academy; fifty-five paintings from his easel were shown at the British Institution, and forty-seven at the Suffolk Street exhibitions; he also contributed occasionally to other London galleries.
Though we find Hancock residing at Marlborough in 1821, it was not until 1825 that he turned his attention to animal subjects and sporting scenes.
At one period of his career, indeed, it would seem that Charles Hancock shared with J. H. Herring the distinction of being the fashionable painter of winning horses on the turf.
In 1832 Charles Hancock exhibited two pictures at the British Institution
The expression "very rising artist " was never more happily used, as that year saw the beginning of Hancock's vogue as a painter of the best race-horses of the time.
No record exists to show the exact date of Charles Hancock's death. His active career as a painter can be traced from 1819 to 1847, the period during which he contributed to the Royal Academy, but there is reason to believe that he attained the age of sixty, in which case it would seem that his brush lay idle in his later years.
