All removable Crockpot™ dish racks (without lids) are safe to use in the microwave and oven set up to 200°F.
Can a pot go in the microwave? Most modern stoneware pot inserts (the actual pot part of your slow cooker) can be used in the microwave. However, remember that the lid is not normally microwaveable and never put the actual heating element in the microwave!
In general, the crock-pot’s removable ceramic inserts are oven safe up to 400°F. They are also microwaveable. The metal bodies and crock pot lids are not oven or microwave safe. This is because they are made of plastic and melt.
If ceramic is fired long enough at high enough temperatures, it can still be safe, but if not, the lead can get into food and cause lead poisoning. Acidic foods or beverages are particularly likely to cause lead to leach out of pottery, unfortunately for coffee drinkers with favorite stoneware mugs.
Most crock pots are traditionally made of ceramic because it supports the best and most even heat distribution. This allows food to maintain its ideal level of heating, even at temperatures as low as 200°F.
In general, low setting on a slow cooker = 190 degrees F and high setting = 300 degrees F.
Right, put your slow cooker on your stovetop for safer slow cooking. Even if you have raised burners, a 6 liter slow cooker will easily fit on top.
