3. Aluminum oxidizes on contact with oxygen and blending it uncovers new surfaces. When you open the lid, oxygen pours in, and if the powder oxidizes fast enough, then it will get hot enough to ignite. To avoid this, open the lid at least every ten to fifteen minutes. Make sure you mill your aluminum in a well-ventilates area and let the powder
