Glass Bar

Start with making a new document. I use 500 by 500 px, it's just an old tutorial habit. Make a shape like mine with the "rectangular marquee tool" (hotkey "M").

Now go to your top menu and under "Layer" choose "New fill layer" then "Gradient...". This will bring up the "New layer" popup. I just skip all this by clicking "ok", but you decide for yourself. The next popup may look diffeent from mine, depending on your color selection when opening a new document, but if you use basic settings this is how it looks:

Just leave all the specs as they are and bring up the gradient adjustment panel by clicking on the gradient bar you have in front of you.

My gradients are custom made by me and I only keep those I frequently use. The darkest color is #1e1e1e and the lighter one is #555555. Make this gradient and click "ok". When you are finished with all of this it's time to add the glass effect. Command click the gradient layer (ctrl for windows users), this will make a selection around your gradient bar. Now in the upper menu select "Select" and "Transform selection". This will make the selection around your gradient bar adjustable. Just lift the bottom a little, just like mine:

Create a new layer (hotkey shift+command+N or shift+ctrl+N). This will make a new, empty layer. Then choose the gradient tool (G) (make sure you have the gradient tool, not the fill tool, see image):

When you have this tool selected, and you have white to white in the color menu (see image), make a gradient in the new empty layer.

Then drag the gradient from bottom to top and deselect the selection by clicking command+D or ctrl+D. Then press the number "1" button on your keyboard (which lowers the opacity of the last created gradient to 10%) and your bar should look like this:

This pretty much sums up the effect itself, but by just crop the image and add some text, I got this:

Hope this helped somewhat.
