My growing Pyrex collection gets used every day, in every way. And that means more hand washing than ever. At any given time you'll find at least one colourful piece in the dish rack. Yesterday the pile was huge as a result of baking a batch of Oatmeal Whole Wheat Malt Syrup Pan Rolls.
It's a known fact that Pyrex colours and patterns are ruined by the dishwasher. Who would want all these cheerful colours to fade away??
All that hand washing is totally worth it.
