"By this time, Chinese metallurgists had discovered how to puddle molten pig iron, stirring it in the open air until it lost its carbon and became wrought iron. (In Chinese, the process was called chao, literally, stir frying.)"
I have considerable doubts as to the value of this short article, which seems to duplicate puddling furnace. I have removed and adjusted a few statements that appear to me to be inaccurate. However it would probably be better to merge it with puddling furnace. Peterkingiron 21:54, 10 April 2006 (UTC)
Merge Proposal with puddling furnace
k, I'll accept your edit for this section. intranetusa 14:00, 31 March 2007(UTC)
Is this only done once after the construction of the furnace to prepare the hearth or is it done at the beginning of the each batch? If it's only done once then I say it should be moved to the furnace section. --Wizard191 (talk) 02:45, 17 January 2008 (UTC)
I have removed material asserting that puddling took place in China by 3rd century AD. It is not disputed that pig iron was made into wrought iron in China using coal as fuel. However, it is a misdesciption to call this "puddling". Many iron articles were spammed a while back with a picture of a Chinese process, usually captioned as "puddling", but the picture did not show the closed reverberatory furnace characteristic of the British puddling process. I fear this is a case of an excess of enthusiasm from some one not familiar with the subject. Peterkingiron (talk) 17:57, 20 March 2010 (UTC)
