What object would soon be replaced by disposable gloves or glue trays in eyelash extension practices?

The option mentioning jade stones is correct because these stones have traditionally been used as a surface for keeping adhesive at a workable temperature and for easy access during eyelash extension application. However, the industry is moving towards more hygienic practices, and disposable gloves or glue trays provide a more sanitary way to handle adhesives and prevent cross-contamination.

In contrast, eye pads, application brushes, and silicone molds do serve important roles in the lash extension process but are not primarily used in the same context as jade stones for adhesive management. Eye pads help with isolation of the lower lashes, application brushes assist in product application, and silicone molds facilitate shaping lashes but are not as closely associated with the adhesive handling practices that are evolving with the introduction of disposable gloves and trays. Thus, jade stones are the object specifically being set for replacement in the specific context of better hygiene.
