Hisgot:Tumbaga

These two sources I found seem to be too related :

1. Page 116 “ COPPER The prevailing name for it is tambaga, a corruption of the Sanscrit tamra, and this corrupt form of the word extends from Sumatra to the Philippines, a fact from which its dissemination may be traced to a single nation, most probably the Javanese. The use of copper in Java, chiefly in the formation with tin and zinc of alloys, is attested to have been of considerable antiquity by the discovery in old ruins of many statues and utensils of bronze, and even of copper itself. A Hindu cup, with the signs of the zodiac, in the collection of Sir Stamford Raffles, bears the date, according to the era of Salivana, 1220, and two in my own possession, those of 1241 and 1246. The oldest of these carries us back to the year 1298 of Christ.” —-A descriptive dictionary of the Indian islands & adjacent countries by John Crawfurd, F.R.S. published 1856--BuhayPinoy (talk) 19:56, 25 Pebrero 2017 (UTC)[reply]
