The RHX process produces an increase in specimen weight.
This weight increase provides an accurate measure of the extent of rehydroxylation.
The time frame is generally from the beginning of the nineteenth century to the First World War (1920).
Many crafts underwent industrialization and technological change during this period.
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.
This reaction reincorporates hydroxyl (OH) groups into the ceramic material, and is described as rehydroxylation (RHX).
That means that the play was without fail written after (in Latin, post) 1587.
This usually requires what is commonly known as a "dating method".These changes sometimes left temporally sensitive indications at the level of the artifact.The reader must appreciate that as one comes closer to the present the diversity of artifact types increases geometrically.Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
