A crystallizing dish is a beaker with a very large diameter and short height. Its large surface allows for the solution to evaporate faster, which is necessary when recrystallizing compounds, hence its name.
While similar to evaporating dishes, the crystallizing dish is not generally used to completely evaporate the solution.

General
The crystallizing dish is basically a short and flat beaker, with or without a spout. Comes in two varieties, thin walled and thick walled. It is made of borosilicate glass, though plastic and porcelain crystallizing dishes are available, though they're rarely used. Metal vessels are generally not recommended to be used, since there is a risk of contaminating of the final product, especially during the process of scrapping off the crystals.
Availability
Crystallizing dishes can be bought from lab suppliers or online.
Alternatives
Glass baking dishes, used in kitchen for cooking, can be used as a replacement for the crystallizing dish.
In general, any vessel with a flat and smooth inner surface, with no inner sharp edges, be it made out of glass, ceramic or plastic, can be used as crystallizing dish. Avoid any vessels that have their brand printed on the inner surface, as this can and will interfere with the recrystallization process, and is not easy to clean.
