Pre-fabricated, custom pre-designed, high-density engineered solid surface products, including countertops and other architectural surfaces such as vertical wall surfaces and decorative panels and a method of manufacture of unitary custom-fit interior and exterior engineered solid surface products that are stain resistant, moisture impervious, UV resistant, acid resistant, dimensionally stable, abrasion and impact resistant, and are glazed to produce unique decorative and utilitarian surfaces in a wide range of colors and textures, including artistic, one-of-a-kind works. The glaze surface includes exterior vertical edges on countertops and back-splashes that are continuous with the top surface color and design. Optional flaming (open flame treatment or flame painting) or texturing of the post-glazed surface produces in a wide range of finishes, including a leather-look finish for crazed glazes. The invention includes custom-glazed monolithic engineered solid surface products that do not require site cutting, as a result of the inventive process.

Provided is a method for producing an airtight package that can reduce thermal stress occurring in the inside of a glass lid due to irradiation with laser light to prevent occurrence of cracks and the like in the glass lid. A method for producing an airtight package in which a container 1 containing a device 5 mounted therein is sealed with a glass lid 3 includes the steps of: mounting the device 5 to an interior of the container 1; disposing a sealing material 6 between a frame 2 of the container 1 and the glass lid 3 and placing the glass lid 3 on top of the frame 2 of the container 1; and irradiating the sealing material 6 through the glass lid 3 with laser light while scanning the laser light along the frame 2 to melt the sealing material 6 by heat and form a sealing material layer, thus sealing the glass lid 3 and the frame 2 together with the sealing material layer, wherein irradiation with the laser light is started from an irradiation start point B, then performed by scanning the laser light a plural number of times all around along the frame 2, and then terminated at an irradiation end point C located ahead of the irradiation start point B in a direction of the scanning A.

A biocidal additive package comprises at least one metal or metal containing compound selected from the group consisting of Cu.sub.2O, Cu(OH).sub.2, Cu, CuO.sub.3, Cu.sub.2O.sub.3, and a combination thereof, and at least one non-copper metal or non-copper containing metal compound.
