Cut the soap base into 1 inch cubes and divide between 2 4 cup spouted measuring cups.

Heat both at the same time for 30 second intervals in the microwave, stirring in between each heating session, until fully melted.

Stir the chai tea into one cup of soap base, then stir the essential oil into the other cup of soap base.

Allow soap to cool slightly, then slowly pour both at the same time to swirl.

Sprinkle a bit of chai tea on the top.

Allow soap to set overnight, then use the wavy cutter to cut into 1 inch bars.
