Caring for your vintage Pyrex

I have been reading over at Pyrex Love on how to care for your vintage Pyrex. I have been getting a nice collection going and I want to take care of them. I know you should not put them in the dishwasher. You will ware the pattern/color down and it will start to fade. I did not know you should not stack them. They are saying its the worst way to store them. They pointed out how on Ebay some sellers stack the bowls on top of each other to show the colors off. Well they run the risk of scratching up the bowls. They said you should put something between them if your going to stack. They should cover completely and not touch each other. Yikes. I have some of my Pyrex stacked. I am going to gather all the bubble wrap sheets I can find.

I found a blue floral Pyrex bowl. I also found 2 shakers and a mod vintage floral bed sheet.
