Green fire is special case; the color is more a reflection of the chemical composition of the material being burned than the heat of the fire itself. For example, burning copper compounds can produce a vivid green flame. While the exact temperature of a green fire can vary depending on the...
Many classes of flame retardant products can have a deleterious effect on the aging properties of polymers. In addition, there can be reactions between FR materials and stabilizers. This paper will discuss these effects and the process for selection of the most effective stabilizer systems that can...

Normally, aromatic compounds will dissipate into the air in the kitchen or over your grill. At the same time, moisture dissipates, which means that what's left of your spices sticks firmly to your meat. With sous vide cooking, there's no way for that flavor to escape the bag. Meanwhile...
Even tiny droplets of a diluted bleach spray can find their way into your lungs and trigger asthma or make it worse in people who already have it. Many other household items give off toxic gases called volatile organic compounds, or VOCs. In the short term, VOCs can harm your eyes, ...
Unfortunately, there's no regulation for organic mattresses, so anyone can claim that their mattress is "organic" or "natural" without having to meet specific requirements. While there is no legal standard, there are some independent organizations that may help eco-conscious parents find a mattress...

When you ignite one end of the cord, the explosive material inside it burns at a steady pace, and the flame travels down the cord to the detonator on the other end. When it reaches this point, it sets off the primary charge. Blasting caps are used as a catalyst to set off the ...
