In 1970, Spencer Silver attempted to produce the strongest ever glue, he failed and as a result which product was born?
Spencer Silver Spencer Silver Spencer Ferguson Silver, an American chemist who worked together with Arthur Fry to invent the Post-it notes in 1974. (disputed) Silver was born in San Antonio, Texas. He majored in chemistry at Arizona State University, earning a B.S. in 1962, then earned a doctorate in organic chemistry from the University of Colorado at Boulder in 1966, before taking a position as a Senior Chemist in 3M's Central Research Labs. Silver is now named on over 20 US patents; however, his most significant invention was not an immediate success. In 1968, Silver developed a high-quality but "low-tack" adhesive, made
Animal glue tests performed by Mark Schofield of Fine Woodworking Magazine, "liquid hide glue" compared favourably to normal hide glue in average strength of bond. "However, any liquid hide glue over six months old can be suspect because the urea eventually hydrolyzes the protein structure of the glue and weakens it – even though the product was 'protected' with various bactericides and fungicides during manufacture." Animal hides are soaked in water to produce "stock." The stock is then treated with lime to break down the hides. The hides are then rinsed to remove the lime, any residue being neutralised with a weak
