  • the cylindrical container is heated briefly at a temperature at which the surface temperature of the sidewall of the container is 330 K to melt any errant powdered wax layer particles on the sidewall of the container.
  • the outer region and corresponding outer perimeter of the first powdered wax layer now has an interface surface complimentary to the molding tool with short, shallow waves and is visible to an observer through the transparent glass of the container.
  • a first solid wax layer is then poured over the top of the powdered wax layer.
  • the first solid wax layer comprises an apothecary blend.
  • the first solid wax layer has a melting point of about 320 K.
  • the first solid wax layer has a red color, achieved through the addition of Scarlet Red Dye Flake DF20001.
  • the Scarlet Red Dye Flake DF20001 is present at 0.65% by weight of the first solid wax layer.
  • the first solid wax layer does not have a scent component.
  • the first solid wax layer covers the top of the first powdered wax layer, but only at a volume that occupies yet another 25% of the rectangular container.
  • the candle assembly is allowed to cool until the first solid wax layer has solidified.
  • a second powdered wax layer is then added.
  • the second powdered wax layer is comprised of the same material as the first powdered wax layer.
  • a sufficient volume of the materials comprising the second powdered wax layer is added such that the second powdered wax layer occupies another 25% of the total volume of the rectangular container.
  • the outer region of the second powdered wax layer is compressed in the same manner and with the same molding tool as provided for the outer region of the first powdered wax layer.
  • the outer region and corresponding outer perimeter of the second powdered wax layer now has an interface surface complimentary to the molding tool with short, shallow waves and is visible to an observer through the transparent glass of the container.
  • a second solid wax layer is then added to cover the top of the second powdered wax layer.
  • the second solid wax layer is comprised of the same material as the first solid wax layer.
  • the second solid wax layer is poured in a sufficient volume to ensure that it extends upward from and completely caps the highest point of the second powdered wax layer, while still leaving sufficient space before the upper edge of the rectangular container.
  • the candle assembly is allowed to cool until the second solid wax layer has solidified.
  • the candle assemblies described herein generally include a form, at least one candle core, at least one layer of powdered wax wherein the outer region is compressed, and at least one layer of solid wax.
  • the methods of making such candle assemblies described herein generally include positioning at least one candle core in a form; loading the form with at least one layer of powdered wax and compressing the outer region of the at least one layer of powdered wax with a molding tool having a non-horizontal compression face to form the interface surface of the outer region of the at least one layer of powdered wax into a similar non-horizontal interface surface, the outer perimeter of which is visible to an observer in the finished candle assembly; and pouring at least one layer of liquefied fuel substance to form a solid wax layer over the at least one layer of powdered wax.
  • the candle assemblies and methods of forming such candle assemblies may also include the at least one powdered wax layer having a first color or first combination of colors and a first scent component or first combination of scent components and the at least one solid wax layer having a second color or second combination of colors and a second scent component or second combination of scent components.
  • the embodiments described herein provide unique aspects including candle assemblies that are aesthetically distinct and have enhanced visual and aromatic properties and methods of forming those candle assemblies that are more efficient and result in aesthetically distinct candle assemblies with enhanced visual and aromatic properties.
