This is exactly what I’ve been looking for.  I have had  two marble ones but I refrained from putting it in the dishwasher until my husband did when I was out of town.  He felt it would be sanitized going through the dishwasher.  I had to agree but the glaze wore off and I wanted to replace it with a more durable and practical one.  Paying 50 for a butterbell was more than I was willing to spend.  I saw this one and it’s perfect.  It even has a cold water fill line.  Dishwasher safe and it is labeled Butter on it.  Love it!
