Ten borosilicate glass containers in 4.4 cup and 1.6 cup sizes, with tempered glass lids rather than plastic ones. Borosilicate is the reason for the temperature range: it takes -4 F to 950 F, so a dish can be frozen, baked and brought to the table without being decanted.

Set contents

• Tempered glass lids with removable silicone gaskets

Specifications

The gaskets lift out for cleaning and should be removed before oven use. Wide temperature tolerance is not the same as thermal shock immunity – let a frozen dish stand before it goes into a hot oven.
