I have always broken in my gloves with oil and practice. I decided to hurry this one along by using the suggested oven tip I have heard about in the past. “Oh, just put your glove in the oven!” I never believed them, because I feared it would catch fire. I thought I was wrong. My Easter was ruined today.

Sure. Did I get the terminology wrong? In either case the exposed heating element toasts the contents, rather than just baking them, which may be undesirable depending on what you’re making. The size of the oven doesn’t matter.
