Abstract
A method of production of glass reaction vessels includes irradiating a laser beam of a wavelength for which a first glass plate is transparent onto the surface of the first glass plate. The first hiss plate is etched. Etching of the first glass plate is terminated when the recesses extend, over only a portion of the thickness of the first glass plate and therefore the recesses have a bottom formed in the first glass plate as a single piece.
