When Pyrex was bought out, they changed the design slightly (flat top edge - no scallop) and also changed the formula. The new ones are likely to break in the microwave whereas the old "vintage" ones are amazingly resilient.
Question: does anyone know where you can still get the old vintage ones? I looked at ebay where the prices are pretty reasonable, but they charge upwards of $15 for shipping 6 of them!!
