Abstract
A method of manufacturing an item, notably a culinary item, includes: providing a support in the form of a preform; preparing a sol-gel composition; hydrolyzing the sol-gel precursor, followed by a condensation reaction; applying onto at least one support surface of the preform at least one layer of the sol-gel composition to form a sol-gel coating layer; and thermally treating the sol-gel coating layer to solidify the coating layer. Further, before thermally treating the sol-gel coating, the method includes pre-densifying the coated preform and stamping the preform to produce a final form of the culinary item.
