The halogens or halogen elements (/ˈhælədʒən, ˈheɪ-, -loʊ-, -ˌdʒɛn/) are a group in the periodic table consisting of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The artificially created element 117 (ununseptium) may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17.
The name 'halogen' means 'salt-producing'. When halogens react with metals they produce a wide range of salts, including calcium fluoride, sodium chloride (common salt), silver bromide and potassium iodide.
The group of halogens is the only periodic table group that contains elements in three of the four main states of matter at standard temperature and pressure. All of the halogens form acids when bonded to hydrogen. Most halogens are typically produced from minerals or salts. The middle halogens, that is chlorine, bromine and iodine, are often used as disinfectants. Organobromides are the most important class of flame retardants. Elemental halogens are lethally to dangerously toxic.

Seems just about anything can be cooked in the halogen oven. for more Halogen oven videos visit: http://www.dereton33.co.uk
Chef Tony Scruggs of Fox's MasterChef explains the features and benefits of the Fagor Halogen Oven. The Halogen Oven works like a standard oven but cooks up to 50% faster and saves energy. The halogen oven heats up instantly, reducing preheating times while a convection fan circulates hot air internally to cook food evenly and seal in natural juices for full flavor. In addition, it is compact in size so it is perfect for any kitchen, cooking space or anywhere you like to cook like a recreational vehicle, a dorm room, a hotel, a picnic, camping or even the office.

Thought I'd wait until I was old
I've resigned and fallen out of love
Now I wait on a bridge
For myself to heave the weight of all my yesterdays
Carlights fade across the bridge in even tides
Seems the night was made for passengers
Now I wait on a bridge for time to pass
Dissolve my sins, dissolve the emptiness
I would wait here for a lifetime, still
It's not the glory of pure will
For now, I'm standing here to sink
To fall on in, to fall on in
Now I'm waiting here for you
It's such an awkward thing to do
Is my mind wrecked inside?
All I've lost is a fear of falling
I would wait here for a lifetime, still
It's not the glory of pure will
For now, I'm standing here to sink
To fall on in, to fall on in
Now I'm waiting here for you
It's such an awkward thing to do
Is my mind wrecked inside?
All I've lost is a fear of falling
On and on
I can't go on
The liquid pulls me in
On and on, the rising tide
On and on
I can't go on
The liquid pulls me in
On and on, the rising tide
How'd I end up here so alone?
I have cried but never learned to love
Now I 'm worn into a bridge, awaiting signs
of happiness beyond a desperate tide
Carlights fade across the bridge in even tides
Seems the night was made for passengers
Now I wait on a bridge for time to pass
Dissolve my sins, dissolve the emptiness
On and on...
