Alter Substance

You convert one type of material into a similar type of material. For example, you can change one type of metal into another, one type of liquid into another, one type of fabric into another, one type of stone or gem into another, one type of wood into another, etc.

Choose an object or objects that you can touch for the duration. You can alter the type of material of a medium or smaller object (contained within a 5-foot cube). The size and shape of the object do not change, only the properties of the material. Any flaws in the original object will remain after being altered.

Creatures or magic items can't be altered by this spell.
