* The maximum quality of the resulting [[mortar]] is equal to the [[heap of sand|sand]]'s quality.
* [[Mortar]], like [[clay]], takes [[damage]] after a couple of hours. To increase its lifetime, put it into a [[container]].
* If you fail to create the [[mortar]], 0.20kg will be consumed from the clay and [[heap of sand|sand]] anyway.
* [[Mortar]] can be combined and still used in [[Stone house|house building]]. After each [[Stone brick|brick]] is added, 2kgs of [[mortar]] will simply be removed from the combined lump.
* Can also be used in the creation of [[concrete]] when combined with [[lye]].
