Taxidermy Preservative Alum and Borax

Listed among Ace's taxidermy inventory, borax's inclusion underscores the Victorian context of preservation techniques Josiah employs. Its mention blends into the scene's scientific discussion before the supernatural confrontation shifts focus toward concealment.

Borax is pointed out by Ace alongside other preservatives, its presence normalizing the scene until the Doctor and Smith weaponize language around unauthorized access, transforming the chemical list into a lexicon of threat.

Borax appears alongside alum as one of the taxidermy preservatives Ace examines in the cupboard. Its presence contributes to establishing the Victorian-era chemical stash that identifies Gabriel Chase as a site of sinister preservation experiments.
