 Quality grades
All crafted items (e.g. furniture, armor, clothes, prepared meals) have quality levels. If the quality of their craftsdwarfship is above standard, the item name is bracketed by characters that show it (see table below).
| Weapon To-Hit /|
Armor Deflect Modifier
|*Item Name*||Superior quality||4x||unknown|
|«Item Name»||Decorated object||Varies||unknown|
Decorations have quality levels, too. An item of any quality (except artifacts) can have a decoration of any quality. (There are no artifact quality decorations.) The quality level of a decoration is shown by the same signs (-, +, *, ≡, ☼) just outside the double angle-brackets («,»). Thus, a *«+steel battle axe+»* is a finely-crafted steel battle axe with superior decorations on it, and a «☼steel battle axe☼» is a masterfully crafted steel battle axe with decorations of standard quality.
 Quality levels in stockpile settings
Stockpiles can be set to accept only goods of certain quality levels. However, the Core quality and the Total quality which can be set in a stockpile's settings are in a difficult relation to the crafting and decoration quality.
 Core Quality
Core quality means the quality of the craftsdwarfship of the item. A masterfully crafted armor (made from qualityless metal bars) has masterful core quality. A finely-crafted dress (made from an exceptional pig tail fiber cloth) has fine core quality (because the craftsdwarfship of the item is fine).
 Total Quality
Total quality means the highest between the craftsdwarfship of the item and the craftsdwarfship of its components (or decorations). The finely-crafted dress from our previous example has a fine core quality, but its total quality is exceptional because its component — a pig tail fiber cloth — is of exceptional quality. Likewise, a superior quality steel gauntlet, masterfully studded with copper is of masterful total quality (and superior core quality).
A more complex example: A rope reed fiber sock is superiorly decorated with pond turtle shell. Is masterfully crafted from a rope reed fiber cloth which was finely dyed with redroot dye. Core quality: masterful, Total quality: masterful. (Remember, for total quality, the best of either the item's quality, the quality of its components, or the quality of its decorations is chosen.)
 Admiring furniture
Quality has an impact on the amount of happiness a dwarf gets from admiring furniture only to the extent that it contributes to the furniture's value. That is, if there's a no-quality statue and a masterwork statue which have the exact same monetary value, they'll each give the same amount of happiness when admired (assuming the dwarves have no preference for the material of either statue). Furniture quality has no influence on how often a piece of furniture is admired.
 Changes to artifact weapons
Toady gave us a quote on weapon and armor quality, giving the game qualities of an "artifact" in v0.31:
