Glass and metal tray: the material involved in the result

Useful to know

Glass and metal baking dishes transfer heat differently. King Arthur discusses how the material can affect baking at the centre and around the edges. [1]

When a recipe specifies the material, treat it as part of the method. After a substitution, do not judge doneness only by the colour on top; use the descriptions given for the centre and edges. Avoid temperature changes that the dish is not designed to withstand. The permitted use must be checked for the actual product.
