What year are You in Pyrex?

Pyrex has been produced in the United States for what seems FOREVER. But it wasn't until 1945 when they came out with first the UnNumbered COLORED milk glass bowls that we all refer to as "Pyrex Dishes".

Those first dishes were the Primary set and after the initial year or two is when they realized that they were going to have to start giving a Style Number to each piece for tracking/inventory/production purposes. Luckily for us now because that is how a lot of us reference the specific size we are looking for or just found πŸ’–
