Safe with refractory laminate walls

A container having a laminate wall constructed to be resistant to the cutting effects of high temperature torches and to the drilling effects of high speed drills, said wall comprising:

• a) a hardened steel outer panel;
• b) a hardened steel inner panel;
• c) a refractory abrasive layer disposed immediately adjacent the hardened steel outer panel;
• said refractive abrasive layer comprising a composite containing silicon carbide granules of a coarse size and silicon carbide granules of a fine size for hindering drills of various sizes,
• d) a thermally insulating porous ceramic layer of vitreously bonded ceramic fibers and having interstitial spaces between the ceramic fibers, said thermally insulating porous ceramic layer being disposed immediately adjacent the hardened steel inner panel, said thermally insulating porous ceramic layer consisting of vitreously bonded ceramic fibers made of a mixture of materials selected from the group consisting of silica, alumina, and zirconia, said thermally insulating porous ceramic layer functioning to retard heat transfer from said hardened steel outer panel to said hardened steel inner panel,
• said ceramic fibers being vitreously bonded by a flux selected from the group consisting of oxides of boron, silicon, and alkali and alkaline earth elements,
• e) a substantially water-tight receptacle enclosing said thermally insulating porous ceramic layer,
• f) water occupying the interstitial spaces between the ceramic fibers and contained within the substantially water tight receptacle for providing additional thermal protection, and
• g) a thermally conductive layer of copper disposed between the refractory abrasive layer and the thermally insulating porous ceramic layer and having a thermal mass sufficient to inhibit melting of said inner hardened steel panel when heat is applied by a high-temperature torch to said outer hardened steel panel.
