(b) an array of groove retaining tabs having first tab edges, said first tab edges protruding from said sheet having at an upward angle of less than about 45 degrees, for a distance of less than about one quarter inch; and (c) an array of mortar lock tabs having second tab edges, said second tab edges protruding from said sheet at a downward angle of greater than about 45 degrees, said array of mortar lock tabs being offset vertically from said array of groove retaining tabs, wherein, said array of groove retaining tabs are adapted to engage shallow dovetail grooves formed in the rear of thin bricks, and said mortar lock tabs are adapted, when embedded within a cured mortar matrix, to exert, in response to a tensile force away from said metal sheet, a force along a vertical axis, on the brick, in an opposite direction to a force applied to the brick along a vertical axis by said groove retaining tab, to thereby retain the brick against the panel. ### Claim 2 (depends on 1) The support panel according to claim 1, wherein the metal sheet comprises galvanized steel. ### Claim 3 (depends on 1) The support panel according to claim 1, wherein the metal sheet comprises aluminum. ### Claim 4 (depends on 1) The support panel according to claim 1, wherein said groove retaining tabs comprise forwardly deflected central portions of semicircular perforations in said sheet. ### Claim 5 (depends on 1) The support panel according to claim 1, wherein said mortar lock tabs comprise forwardly deflected central portions of semicircular perforations in said sheet. ### Claim 6 (depends on 1) The support panel according to claim 1, wherein said groove retaining tabs extend upward and forward at an angle of about 18 degrees. ### Claim 7 (depends on 6) The support panel according to claim 6, wherein said mortar lock tabs extend downward and forward at an angle of about 83 degrees. ### Claim 8 (depends on 1) The support panel according to claim 1, wherein said metal sheet comprises galvanized steel, said groove retaining tabs and mortar lock tabs comprise deflected central portions of semicircular perforations having a radius of about 5/16 inch, said groove retaining tabs extending upward and forward at an angle of about 18 degrees and said mortar lock tabs extending downward and forward at an angle of about 83 degrees. ### Claim 9 (depends on 1) The support panel according to claim 1 in combination with a thin brick having formed on a rear face thereof a dovetail groove having a depth less than about one quarter the thickness of the brick. ### Claim 10 (depends on 9) The support panel according to claim 9, in combination with a mortar adapted for filling a space between adjacent bricks and curing to a solid material. ### Claim 11 (depends on 1) The support panel according to claim 1, further comprising a plurality of thin bricks having a shallow dovetail groove formed in a rear surface thereof, the shallow dovetail groove having a rear wall and two diverging sidewalls, mounted on said array of groove retaining tabs with gaps therebetween such that the first tab edges are seated within the upper inclined edge of the shallow dovetail grooves formed in the rear of the thin bricks and the mortar lock tabs are disposed in gaps between adjacent rows of thin bricks; and a curable mortar filling the gaps between the thin bricks to thereby encase the mortar lock tabs, wherein in response to a tensile force away from said front surface, the mortar lock tabs exert a downward force component, to thereby counter an upward force component exerted by the first tab edges acting on the shallow trapezoidal grooves. ### Claim 12 (depends on 11) The support panel according to claim 11, wherein the panel comprises a set of markings defining a thin brick placement pattern, wherein the plurality of thin bricks are placed on said array of groove retaining tabs in accordance with the thin brick placement pattern. ### Claim 13 (depends on 11) The support panel according to claim 11, wherein the panel comprises galvanized steel, said groove retaining tabs and mortar lock tabs comprise deflected central portions of semicircular perforations having a radius of about 5/16 inch, said groove retaining tabs extending upward and outward at an angle of about 18 degrees and said mortar lock tabs extending downward and outward at an angle of about 83 degrees. ### Claim 14 (depends on 11) The support panel according to claim 11, wherein said first tab edges, and second tab edges protrude from said metal sheet from a same side thereof. ### Claim 15 A support panel for thin brick, comprising; (a) a metal sheet having a front surface and a rear surface; (b) an array of groove retaining tabs having first tab edges formed in said metal sheet, said first tab edges protruding from said front surface of said sheet at an upward angle of less than about 45 degrees, for a distance of less than about one quarter inch; and (c) an array of mortar lock tabs having second tab edges formed in said metal sheet, said second tab edges protruding from said front surface of said sheet at a downward angle of greater than about 45 degrees, said array of mortar lock tabs being offset vertically from said array of groove retaining tabs, said first tab edges being adapted to engage an upper edge of a shallow dovetail groove formed in the rear of a thin brick, and said second tab edges being adapted to be embedded within a cured mortar matrix between adjacent rows of thin brick, to exert on the thin brick, in response to a tensile force along an axis away from said front surface, a force having a downward component along a vertical axis, to thereby counter a force having an upward component along a vertical axis exerted by the first tab edges acting on the shallow dovetail groove, to thereby tend to retain the thin brick against said front surface of said sheet. ### Claim 16 (depends on 15) The support panel according to claim 15, wherein said groove retaining tabs comprise portions of said sheet deflected forward from semicircular perforations in said sheet. ### Claim 17 (depends on 15) The support panel according to claim 15, wherein said mortar lock tabs comprise portions of said sheet deflected forward from semicircular perforations in said sheet. ### Claim 18 (depends on 15) The support panel according to claim 15, wherein said groove retaining tabs extend forward and upward at an angle of about 18 degrees, and said mortar lock tabs extend forward and downward at an angle of about 83 degrees, with respect to a front surface plane of said sheet. ### Claim 19 (depends on 15) The support panel according to claim 15 in combination with a plurality of thin bricks having a thickness of less than about one inch, having formed on a rear face thereof a shallow dovetail groove having a depth less than about one quarter the thickness of the brick, and a mortar matrix composition filling a space between adjacent bricks and curing to a solid material. ### Claim 20 (depends on 15) The support panel according to claim 15, wherein metal sheet comprises a set of markings defining a thin brick placement pattern.
