  • Enhanced infrared energy reflecting composition and method of manufacture
    Patent number: 5905269
    Abstract: An infrared energy reflecting enamel composition comprises a ground coat of enamel on a substrate and embedded TiO.sub.2 particles in the ground coat of enamel. The infrared reflecting enamel composition has an infrared energy reflectivity value of at least 80%. A method for manufacturing the composition is also disclosed for embedding the TiO.sub.2 in the enamel.

  • Infrared energy reflecting composition and method of manufacture
    Patent number: 5898180
    Abstract: An infrared energy cooking and heating apparatus comprises an infrared layer or reflective coating, particularly on inner panels of ovens or other cooking devices. The coating is preferably an enamel and reflects the infrared energy to the food being cooked and heated. In particular, the infrared cooking apparatus are substantially faster than such processes in conventional ovens, and offer improvements in foodstuff cooking times. The enamel comprises metal oxide particles that enhance the infrared energy reflectivity of the enamel. Further, the metal oxide particles in the enamel can be formed in several ways so as to enhance the reflectivity.
