the molten iron cool to form a solid
There is no such thing. A solid and a gas are mutually exclusive properties. (In the same way, a car that has only one color of paint cannot be both red and blue.) If the question you mean to ask is what is an opaque gas (a gas you cannot see through well), gaseous iodine is good example.

In the U.S., a Red light always means stop. If the red arrow is to the right, you may turn after stopping if it is clear. In many states you may turn left on a red arrow after stopping if turning onto a one way street.Check your local jurisdiction for traffic rules on red arrows.The new national standard prohibits turning on red at a red right arrow.The red arrow is like the circular red, except that it applies to only the traffic making that turn.
You are allowed to make a left turn at a solid red light only when you are turning from a one-way street onto another one-way street.
In the US, unless there is a sign or signal prohibiting it, you can turn right on a red light. A "right on red" turn may be executed only after a complete stop and then when the way is clear.
