Invincibowl is completely safe to use and will not deliver any aluminum into your lungs. We have done extensive evaluation and produced three proofs to support this fact.

PROOF #1: TEMPERATURE
Aluminum, like virtually all materials, has three states of matter, solid, liquid and gas; think of ice, water and steam.

The hottest point of a pocket lighter’s flame can reach 1970˚C.  SOURCE

The hottest point of a mini-torch’s flame can reach 1430˚C.  SOURCE

At normal environmental temperatures aluminum is in its solid state. It turns to molten liquid at 660 ˚C and turns to gaseous vapor at 2470˚C.  SOURCE  

Since neither a lighter or a mini-torch can produce the temperatures needed to convert aluminum to a gas at atmospheric pressure, even at 10,000ft elevation, there is no way for vaporized particles to be released.

Additionally, the Invincibowl would need to transition from solid, through liquid phase and into a gas phase. We have hundreds of videos and have run dozens of experiments proving, without a doubt, that the Invincibowl does not form molten metal when used.

PROOF #2: MASS
The Invincibowl has a mass of 16,000mg

The average person consumes 10mg of aluminum per day in their food, water and air intake SOURCE

The Law of Conservation of Mass states that matter can neither be created or destroyed.  SOURCE

At 10mg/day the Invincibowl would completely vanish after roughly 4 years of usage. This does not happen,  the Invincibowl's mass remains exactly the same, proving that all of the aluminum atoms remain fixed to the product.

PROOF #3: COATING
The Invincibowl is coated with a layer of hard anodization. This not only gives it cool colors, but provides a 1-mil (about a ¼ thickness of your hair) protective layer which can withstand temperatures up to 2000˚C.  SOURCE

After continual usage and hundreds of heating cycles, the anodized coating remains fully intact. Since the anodized coating is intact, and incredibly thin, we can conclude that no material is being shed, no aluminum is being released. 

BACKGROUND ON ALUMINUM
Aluminum is one of the most abundant metals in mother nature’s crust. Aluminum compounds can be found in trace amounts in all sorts of everyday items such as antacids, cosmetics, sunscreens, and as we mentioned before, in the food, water and air that you ingest.

The connection between aluminum and Alzheimer’s is complicated and widely misunderstood. Varying factors contribute to the disease including organ health, neuro-inflamation, neurofibrillary tangles, and several others. It is not even understood if the disease itself is what causes accumulation of different elements in the brain or vice versa.
 
Metal foundry workers who ingest significant amounts of aluminum, on the order of 1000mg/day, over long periods of time, have been shown to suffer neurological effects. For this reason we highly recommend you not eat your Invincibowl (1600mg)
