How healthy is the older corningware?

Older CorningWare, particularly the ones made before the 1990s, are generally considered safe for cooking and baking. They are made from a durable glass-ceramic material that is non-reactive and can withstand high temperatures. However, it's essential to check for any chips or cracks, as damaged cookware can leach substances into food. Additionally, some older pieces may contain lead in the glaze, so it's advisable to verify safety standards if you're concerned.
