Similarly, ancient Romans dipped wicks into tallow, a rendered form of animal fat, to create another early form of the candle. Other components of candles include plants, insects, seeds and nuts which have been identified in Chinese, Japanese and Indian civilizations.</p> Fri, 25 Jun 2021 17:25:23 +0000 Cat Wang 8770 at /oss
