And they have slipped to fourth in the Championship table.
But they still closed the gap on leaders Surrey by four points, taking seven bonus points and three for the draw, as well as remaining unbeaten since the opening game of the season at Sussex.
And skipper Wasim Akram was unapologetic.
``It's a shame because English cricket needs to be positive at the moment,'' he said. ``But Glamorgan didn't declare early enough on Friday for us to think about setting a target.
``We were ready to bowl at them again, but it was just not possible.''
For the spectators who turned up at Penrhyn Avenue on Saturday, many of them from Lancashire, the fault lay with Wasim.
Glamorgan skipper Matthew Maynard had some sympathy, saying: ``It's very difficult to know what kind of target to set at Colwyn Bay because it is just a small ground.
But he added: ``They have got 10 points for a draw and if they are happy with that, that's up to them.''
Maynard didn't say it, but Glamorgan did not win their championship last season by allowing games to fizzle out like this. The day was not completely wasted for a number of Lancashire players.
John Crawley completed a second century in the match and third on the trot in the championship following his match-winning innings against Worcestershire at Lytham - becoming only the third Lancashire player to do that since the war.
Graham Lloyd also continued his encouraging return to form with a quick 73, his second half century of the match and the season.
And two of Lancashire's youngsters also made the most of their chance. Mark Chilton hit 47 to stake his claim to replace the injured Neil Fairbrother in tomorrow's NatWest quarter final against Notts. And Chris Schofield claimed his first two first team wickets - even if the first was from a full toss.
Lancashire have the ideal chance to make up the ground they lost in North Wales in their next two games, against second placed Leicestershire and third placed Gloucestershire, both at Old Trafford.
But with Surrey still 25 points ahead, even after playing a game more, it is no longer true to say that the destiny of the title is in Lancashire's own hands.
