This display of potions and other objects might be found in Professor Dumbledor's office. Items include a goblet filled with his favorite lemon drops, a crystal ball (filled with wispy spider web batting and a flickering battery-operated candle underneath), pocket watch, chess piece, wand, Triwizzard cup, etc.
All potion ingredients are mixed in a 4-cup measuring cup with corn syrup as the base. I use enough syrup to fill each potion bottle and leave a little head room). Fine glitter, in the desired color, is then mixed in. I start with a few shakes of glitter, slowly adding more to achieve the desired intensity. Fine glitter stays more evenly suspended in the corn syrup as opposed to larger pieces of glitter which tend to settle at the bottom of the bottle, or float to the top. Head room in the bottle will allow the sluggish glitter to be moved within the bottle when it's rocked back and forth. I use a narrow-neck funnel to pour the “potion” into the bottle, and I clean any spills or drips off of the bottle top with a damp cloth.
E600 is my adhesive of choice when securing the cork or lid into the opening of each bottle top which protects the contents. Inking the cork, before gluing it into place, helps me achieve the aged-look I desire.
I found most of my potion bottle labels by doing a Google search for “Harry Potter potion labels.” A few were found on eBay, Etsy.com or were cut from a sheet of paper (see below). I distressed them with Walnut Ink, and many were crumpled and ink added to the wrinkled ridges to give them additional aging. Clear contact paper was added over most labels to preserve them (leaving 1/8” around all edges to help with the seal).
Additional products used were flat black spray paint to cover some bottles, spray frost paint to make glass look dusty and old, wire and old trays to sit the bottles and items upon.
If interested in the lemon drops Google "Honeydukes" lemon drops.
