USE ONLY PURE, COLD WATER
In soaking and thinning glue, use only pure, cold water. Unless heater is provided with pure water attachment or pure water chamber, avoid using water from the glue-heater. Do not use water from boilers, for such water contains pipe-rust, acids from boiler compounds, sediment, and other matter extremely harmful to glue. See to it that all soaking vessels are scrupulously clean.
