Crem
Crem is part of the rain water on Roshar. When crem is ingested it can cause sickness however waiting a day before consumption will allow the crem to settle to the bottom and clean water can be safely drank from the top.
Crem is used in pottery making.[1] The people of Sesemalex Dar are renown for their expert crem pottery.[2]
It is used when deworming fields to close the holes after removing worms,[1] so that no new worms could infest the field again.
Throughout Rosharian history of farmhouses are built of crembricks.[3] Shallan Davar considers if the buildings of Kharbranth were made of crem.[4] When the Parshendi are discovered by King Gavilar and his brother Dalinar it is observed that they made simple buildings of crem and stone.[5]
A problem of crem is that the rainwater deposits stalagmite-like pendants of rock on the edges of roofs. Maintenance is required to clean them off regularly for avoiding roofs collapse.[6]
Crem is used as a derogatory term, i.e. "The crem of an army." or "one cremstained mark."[7]
