'''The Forge''' is a collection of temperaments of different ranks, including subgroup temperaments, that all temper out the [[forge comma]] – the unnoticeable comma with the ratio 1640558367/1638400000, and a monzo of {{monzo|-19 14 -5 3}}.  This collection of temperaments provides the foundation for multiple 11-limit and 13-limit temperament families.
