A transparent solid glue, in mass percentage comprises: 10.0%-50.0% of glycerol, 5.0%-20.0% of propylene glycol, 5.0%-30.0% of sticky substance, 1.0%-10.0% of stearic acid, 0-5.0% of vegetable oil, 0.5%-5.0% of protopine, 0.1%-5.0 of excipient, 0.1%-0.5% of preservative, and 5.0%-70.0% of deionized water, wherein the excipient is C.sub.12-16 saturated or unsaturated fatty acid salt. The prepared transparent solid glue has high initial viscosity; and the drying time is controllable so that the gluing position of the objects to be glued can be adjusted according to actual requirements, which is convenient to use, and the glue exhibits strong adhesion after completely drying. Meanwhile, the addition of protopine causes the pH of the solid glue to be between 10.49-10.99, and accordingly the solid glue is an environmentally friendly solid glue. Within a temperature range from 5 C. to 40 C., this solid glue is widely applicable to gluing paper, wood pieces, photographic paper, paperboards and etc.
