Here's the trick to shooting clear subjects
The trick to shooting small clear objects is to give them their own tiny background that is lit off-camera and that is trimmed so that nothing shows from the camera viewpoint.
Let's take a frosty glass of beer. Cut a card to place behind the glass that bounces light back through the beer toward the lens. Vary the amount of light by changing the distance from the light source to the reflector card. It will help lift the subject off the background, visually.
The problem with shooting against a white background is that transparent object become "blackline." The edges appear dark. It's difficult to light the subject. The more light you use is refracted away making the contrast even brighter.
The opposite happens when you shoot against a black background and the object becomes "whitelined" and the middle becomes dark and the edges glow when you pour more light on the scene.
