Bolesławiec Poland oval pottery serving bowl baking casserole dish pine cones?

This is a large piece of Polish Boleslawiec pottery. It looks like it could be used as a casserole dish or as a serving piece. The pattern is possibly pine cones or maybe just brown dots on a blue background--I haven't been able to identify it. The piece measures approximately 10.5" x 7.25" x 2". There is a bit of wear around the rim and on the bottom but I don't see any chips or cracks. Smoke- and pet-free home.
