Want to boil water faster or prevent your sauce from reducing? Then this 9.5" Gem glass lid is the perfect accessory for your saucepan or casserole. The heat-resistant borosilicate glass prevents the liquid from escaping in the form of steam and keeps the heat in the pan so there's minimal energy loss. When you've reached the desired result, just grab the stylish stainless steel knob to lift the lid and pop it in the dishwasher for an easy clean-up.
