A new type of pint pot is to be introduced into bars to reduce the number of "glassings".
The safety glass shatters into small pieces
Council licensing officers in Rossendale, Lancashire, are testing safety glasses which shatter into small pieces on impact.
The glass is similar to the type used for car windscreens.
Under new legislation, it will soon be possible for councils to demand bars where there have been disorder problems to stock the glasses.
Lancashire Police officer Pc Chris Adams said: "There are many events this year, in particular, Euro 2004, that could be the sparking point for violence.
"We want to prevent that violence, but if it does happen, this product will reduce the effects of it."
