The teacher, a single woman surnamed Yi, would have hurt more children Dec 14 in Xinghua city if she were not stopped by another teacher who was passing by the classroom and heard the children's cries, the China Daily reported Friday.
Yi also threatened the children not to tell their parents and made up the excuse that the kids' scars were caused by "falling down in the toilet".
When Cheng Sixia, mother of one of the victims, Cui, saw the big scar on her 6-year-old son's face, she asked a classmate of her son if he knew what happened to her son.
The boy said Cui was burnt by the teacher with "the thing used to iron clothes".
The city government said Thursday that the kindergarten was privately owned and Yi, who wanted to scare the kids, thought the iron, used for ironing shoe-pads, was not hot after she pulled the plug out.
