I always used to admire the turquoise tumbler glasses on the Saturday Kitchen show. Our tumblers have been gradually reducing in number and I managed to break another one recently so I have decided to buy myself a set as a Christmas treat. I want to avoid anything where the colour has been painted onto the glass as they will be going into the dish washer. Can anyone recommend anything? I don't want to pay crazy prices although appreciate that I will have to spend a certain amount to get reasonable quality.
