I recently broke a Pyrex half pint jug that was originally my mothers and had been owned by our family for at least fifty years. I was amazed to find that none of the shops I visited had anything similar for sale. Fortunately, Google came to the rescue and I found these ones on the Amazon site. I ordered two using my one-click facility and they were delivered by first class post on the next working day. The jugs are perfect for what I need that size for, which is making sauces and gravy or reheating them. Someone, claimed in an earlier review that they aren't suitable for microwaves. This is completely erroneous, as they actually have the "Microwaveable" symbol on the label and indeed that is precisely the first use I put one of mine to. It DOES say "Not suitable for conventional oven use" so maybe the other reviewer misread the label? Just use common sense... allowing a fatty or sugary substance to boil in a microwave, whatever the container, might not be a good idea as their boiling point is much higher than water.
