Is rust dangerous on cast iron cookware?

Answer 1

Cast Aluminum is made by pouring heated molten aluminum into a mold. During this process, microscopic air pockets form in the metal. This means that the resulting cookware items will hold their heat for longer than sheet cookware. It also makes them quick to heat up and they only need a low heat source.

However, they are not so great at distributing the heat evenly and are also quite brittle. If they are dropped, they will probably crack. Cast aluminum cookware is porous and needs to be seasoned.

How Do I Season It?

• Wash the cookware with hot soapy water.
• Dry it and then coat it thoroughly with vegetable oil. The easiest way is to pour the oil onto a paper towel and work it well into all the surfaces.
• Put the well-coated cookware into a 250 degree oven and leave it there for 2 hours.
• Never use scouring pads or detergent on cast ware. Simply wipe it out using a damp cloth.
• If food starts to stick to the cookware, just season it again.

How Do I Look After It?

• Repeated washing in a dishwasher will strip off any seasoning, can cause discoloration and is not advised. Remove the staining by boiling something acidic like tomatoes or apple peelings and then re-season.
• Don't leave it to soak in soapy water
• Don't use steel-wool pads to clean it
• You can use non-abrasive cleaners or a paste made with baking soda and water. se either of these with a gentle, synthetic scourer and your sheet or cast aluminum will shine!

Is It Safe?

Many people are scared to use aluminum cookware as they believe it may cause Alzheimer's disease.

Back in the 1970's, some researchers in Canada reported the finding that people who had died with Alzheimer's had unusually high levels of aluminum in their brains. It sparked controversy - was aluminum the cause of Alzheimer's, or the result of it? Many people were alarmed by this and threw away their aluminum cookware.

More recent studies would seem to indicate that the increased levels of aluminum were due to the Alzheimer's itself. Brains which have already suffered damage from Alzheimer's will allow unusually high levels of aluminum in.

This is not difficult as aluminum is everywhere. The most common elements on Earth (in order of prevalence) are oxygen, silicon, and aluminum. It's in air, water, soil and consequently in the plants and animals that we eat.

So can using aluminum cookware harm me?

Current research believes that it is safe to use. To put it into perspective, many common medications contain aluminum.

• One antacid tablet may contain more than 50 milligrams of aluminum.
• One aspirin may contain between 10 and 20 milligrams of it.
• The World Health Organization says that an adult can safely ingest more than 50 milligrams of aluminum each day. People in the western world naturally consume about 10 milligrams each day and only 2 of those milligrams come from aluminum cookware.

Answer 2

The acid in the food will break down the seasoning that has built up on the surface of the vessel and the food will absorb an awful-tasting metallic taste. Often, the food will blacken as well.

Answer 3

Rust is iron oxide. It is not "dangerous" but it will do three things.

1) Discolor your food

2) Give a strange taste to your food.

3) interfere with the transfer of the heat from the cookware to your food.

Never put cast iron in a dishwasher. You should "season" new cast iron by coating it with good vegetable oil and heating it. When is cool wipe it off.

After cooking anything, wipe the surface then wash by hand wipe off. DO NOT SCRUB to the bare metal. Keep the "seasoned" surface as it is.

Answer 4

Not unless they are rusty. It is more beneficial to use iron pots and pans.

Answer 5

A cast iron pot that has had food in it for a long time can be cleaned and reused safely. You will want to get all of the food off of it first.

Answer 6

Yes but you need to clean the rust off first and then season the cooking implement with hoil and heat.
