product is light gray in color the liquid resinous product may be used as an adhesive for wood and also may be used as a protective coating for wood the solid resin may be softened with heat and molded into useful products such as art objects knobs etc the solid resin is soluble in acetic acid and may be used as a varnish or paint to protect wood it leaves a tough clear resinous product on the wood when dry about 1 mol of the urea disilicate as produced in example 2 and 2 mols of formaldehyde in an aqueous solution are mixed then an acid catalyst dilute hydrochloric acid is added until the ph is 4 to 5 the solution is then heated to 70 u00b0 to 110 u00b0 c while agitating for 20 to 120 minutes or until the desired viscosity is obtained thereby producing poly urea disilicate resinous product the resinous product may be in the form of a thick clear liquid or a while solid the said solid resinous product may be ground into a molding powder it may be molded into useful products such as art objects knobs etc about 1 mol of silica and 2 mols of urea are mixed in water then sodium hydroxide is added until the ph is 10 to 12 the mixture is then heated while agitating until the water evaporates and then heated to above the melting temperature but below the boiling temperature of the mixture while agitating at ambient pressure for 10 to 30 minutes thereby producing diurea silicate about 2 mols of furfural are mixed with one mol of the diurea silicate and heated to just below the boiling temperature of.
