This will only contaminate the food you cook or heat and compromise your health. These days, most of the manufactured microwave ovens come with their turntables already attached inside. Many of them are made of glass while some look like a plate or a tray. It always depends on the brand of your choice. Below is the list of things to remember when cooking. Thus, read on to find out the safety tips in handling your device confidently. Read the user's manual before operating this kitchen device. Check out if what you have bought complies with all of the FDA emission limits. Also look at the interior and see if there are leaks, bents, and other defects that may cause you harm. Some recently released microwave units have their controls installed on the door to add its capacity without actually adjusting the unit s dimensions. Features You will be astonished by the advanced features most microwaves have nowadays. Among such are preprogrammed cooking, sensor cooking, programmable cooking, and combination convection and microwave ovens. Unfortunately, you cannot also be certain that it is safe to use particularly because of the studies surfacing lately. Whether those studies are true or not, it is logical to think that some methods of microwave cooking are indeed dangerous. For one, when we think of microwave, we think of quick cooking method, faster than when we cook over fire. Let's make some comparisons between cooking devices, and perhaps we could throw on the table a little math as well. By rule of thumb, 60% of conventional ovens are powered by electricity, not gas. Now consider the fact that microwave ovens are far more efficient than conventional ovens. If we throw into the equation the 3000 wattage generated by conventional ovens as opposed to 600 watts to 1650 watts by microwave ovens, you can pretty much discern the discrepancy of energy saved when using the latter. Microwaves can also be classified according to their capacities. There are compact microwaves, medium capacity microwaves, and large capacity microwaves. Compact units are usually less than 18 inches wide, 14 inches deep, and 12 inches tall and their capacity is less than one cubic foot. The wattage of such units ranges from 500 to 1000 watts.
