Can I.... Clay pot question

Toast

Can I put a glass bread pan in a clay pot when I bake my bread?

If the clay is pre-heated, you might want to lay some toothpicks on the bottom to slow heat transfer to a cold glass dish and reduce the chance of heat stress on the spots that directly touch the hot clay.

Just remember to throw the grains out after baking.  (compost)  I tried using some baked grains (pie shell weight kept in a jar for that reason) and they never softened up after hours of soaking and cooking.  The joke was on me when I figured it out!   :)
