Maxwell's Equations. We now have the tools to derive some very useful relationships between thermodynamics variables. Maxwell's equations are based on the same principle as was Euler's test for exact differentials, namely that mixed second derivatives of nice functions must be equal.
Depending on the stain technique it can take anywhere from 2 to  24-hours for the stain to dry. For cabinets, you should wait the  entire 24-hours to make sure the stain is â¦not still tacky and to  prevent smudges on the finish.

You can rent a moisture meter from your local hardware store to get an accurate read.
