Pottery is essential for classifying archaeological sites. Organic materials, such as wood and bone, can easily be dated using radiocarbon techniques, but they arent always available or reliable. Until now, there has been no direct method for chemically dating pottery.
Can you radiocarbon date pottery?
What can be dated? For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.
Can clay be dated?
Rehydroxylation [RHX] dating is a developing method for dating fired-clay ceramics. It is based on the fact that after a ceramic specimen is removed from the kiln at the time of production, it immediately begins to recombine chemically with moisture from the environment.

Why is lumber so expensive?
Wood products prices typically fluctuate more than most goods, because homebuilding can move up or down much faster than sawmill capacity can. Lumber and plywood prices are so high now because of the short-run dynamics of demand and supply. Wood demand shot up in the summer of pandemic.
Why are lumber sizes wrong?
Maybe youve noticed that lumber sizes are often misleading. The nominal cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions. The reason is that dressed lumber has been surfaced or planed smooth on four sides (called S4S).
