Ceramic Testing Labs
There is much physical testing you can do using simple procedures and equipment (as described on this site) to compare ceramic bodies, glazes, engobes, etc. Such testing, for example, shows you that one clay is more plastic than another, one glaze has more melt fluidity than another or one engobe has a higher firing shrinkage than another. But if you want data to represent the absolute value of a specific property (e.g. coefficient of thermal expansion, chemical or mineralogical analysis) you may need the services of a testing lab. Most labs have grown over time and offer a wide array of services for many industries, so it can be difficult to locate the specific test you need. Effectively using their services is about knowing exactly what you want, finding their sample preparation instructions for the specific test needed and then following these closely to get the desired result at the expected cost. Having just one test done to answer one question is not typical, normally one has a specific test done on multiple samples, learning to interpret the data over time.
