There are few things in life more satisfying that painstakingly peeling a dried bit of glue off the side of the bottle and rolling it between your fingers. Such was the excitement of using Gloy, the clear glue that managed to enjoy 99.9 percent penetration of Britain’s classrooms. With memorable lower case ‘gloy gum’ logo, the product came in plastic squeezy bottles with a nubbly dispenser on the top which, inevitably, would get good and gummed up after a few squeezes onto crêpe paper and therefore require stabbing with a pair of scissors before you continued. Eventually the rise and rise of Pritt Stick saw Gloy fall out of favour, not helped by the fact that some kid would always make a right mess with it and stick everything to the table. The same was true of its less transparent ‘rival’, Marvin, meaning those essential little green spatulas soon fell into disuse.
