All potion ingredients were mixed in a 4-cup measuring cup with corn syrup as the base. I use enough syrup to fill each potion bottle leaving a little head room at the top. For this potion, perfect pearls powder was mixed in with the syrup. I start with a few shakes of perfect pearls and slowly add more to achieve the desired intensity. Perfect Pearls stays evenly suspended in corn syrup for quite awhile. Head room in the bottle can help sluggish glitter to be moved 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 into place, helps me achieve the aged-look I desire.
I found most of the labels for the bottles by doing a Google search for “Harry Potter potion labels.” A few were found on eBay, Etsy.com, Scrapbook.com, or they were cut from a sheet of paper (see below). I distressed them with Walnut Stain 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).
