nothing, the size of any metal usually expands when heated, but unless you are heating it in a forge also you have to heat it almost to melting point.
14k is 14k in gold, f6 is the band size
'F6' for Female size 6 on the band in a silver ring. Gold pieces would include karat as well, so a gold band could read 14k F6.

There is no definitive answer to this question as the stamp could mean a variety of things. It is possible that 10KSR is the maker's mark or initials of the person who created the ring. It could also be a quality mark denoting that the ring is made of 10 karat gold. Alternatively, the stamp could be a code used by the jewelry store or designer to indicate that the ring is a size 10. Without more information, it is difficult to say for certain what the stamp means.
"K" doesn't stand for ring size, but the amount of gold in the ring.
The amount of raw gold ore that is needed to make a size 12 men's ring will vary. It will depend on the karats, and the actual size of the ring. If the ring is completely made up of gold and is 14 karats, about one ounce will be sufficient.

14k is 14k in gold, f6 is the band size
Increases If the gap can easily be conceived as a small break in a metal ring, then the expansion of the metal ring may decrease the gap size.
It depends on the size of the ring, the larger the ring is, the more gold it takes to make it so the more expensive the ring becomes. Also, the thickness plays a major part too, a small, thin band of gold isn't as expensive as a large, thick band of gold.
probably, depends on size, take it to a jewler and have it appraised
I think it might mean the size.
Markings on the inside of a gold ring indicate many things. The number markings could tell the owner how much gold is actually in the ring. for example 14k means 14 karats. The letter could tell the owner if it is gold plating, or gold filling. Sometimes, these letters and numbers are a combination of ring size and the creators mark.
The weight and purity are not related. A karat is a measure of purity when talking about gold, while a karat for a diamond is dependent on size so if the 10K and the 18K rings are approximately the same size, I would say that the 18K is heavier
Probably not because the HGE mark indicates that it has heavy gold electroplate, not solid gold.
