Bake Eggshells for Compost

I put eggshells in a tray at the bottom of the oven. They get baked and brittle every time you use the oven. Just keep adding to the tray until it is full. Crush the eggshells by hand or use a pastry roller to reduce them to very small pieces or use a grinder - they are now ready to add to the compost.

Ever seen compost with large eggshells? - it is horrible to use - certainly not suitable for seedlings. I am a volunteer 'Compost Champion' for Somerset, England.
