@Icegoddess - Yes, the baking time definitely needs to be shortened—good point.
For most quick bread recipes, I'd recommend checking the mini loaves (with a skewer or toothpick in the center) around the 30-minute mark. At that point, they may be done or they may need another 5-10 minutes. For savory recipes such as meatloaf, start checking around the 40-minute mark; it's best to use a thermometer to make sure the meat is thoroughly cooked (at least 150 degrees to support the final carryover cooking while it cools a bit). Since these are stoneware bakers that retain heat, you may also want to lower the temperature for your recipe by 10-15 degrees, especially if your oven tends to run hotter than normal.
