Print will lighten.
I thought this was glass, but even better! However the first time my husband used it to marinate steaks, the color of the print went from very dark black, to lighter black or almost olive greenish??? Not a huge difference, but you can definitely tell. Not sure if the steak sauce did it or what, but I didn't read any warnings about that. It says it can even go in the microwave and oven, but I wouldn't based on the print issue. Just saying. Seems much more durable than glass will be as far as breaking.
