What are the glasses made of?
Can you brew right into the glasses with ice in them or is it a material that will shatter with the extreme temperature change?
It's always better to be safe than sorry. Even tempered glass can shatter. My advice, brew than pour over ice. I have always been told to put a stainless steel spoon in into a glass when pouring in hot liquid into glass to avoid shattering. Best Wishes.
