1. first open photoshop then open a your favorite image for example I will use this “Drops on leaf” image.
2. Go to layer then create new layer (a transparent layer)

3. then click the rounded rectangle tool then change it’s radius to 7px then draw a rectangle in any size like shown in this picture.

4 after that go to layer>layer style>blending options then follow this pictures:

5. then after that click ok to apply then change the opacity to 90% and fill to 20% (or any value that suits you)

6. then it’s done it’s that easy but you can save it as a separate glass png of your own just hide the view of the background “Drops on Leaf” follow this screenshot then save it as png

7. you can also add an overlay image or a light effect on the glass like the stream.png light effect or my WhiteFlame glass effect which is the one im using just click the selection using magic wand (the rounded rectangle then copy the stream.png for example) and paste it into the selection like in this screenshot

8. after that choose your desired opacity for the overlay image for example 30%

9. after that you can manually create a glow effect on it’s sides just draw with a colored 1px line tool or any method you like and it’s done hope it helps ^_^
