Glasgow rattled up 27 points in the first-half en route to a fine 33-11 win over Gloucester that keeps alive their hopes of progressing in Europe.
A fiery opening at Firhill on Friday shook the visitors as Scotland's forgotten man Dan Parks slotted two penalties in the first five minutes.
The Glasgow playmaker then went from hero to villain as a skewed kick gave Gloucester their only field position of the opening ten minutes and Nicky Robinson opened the scoring for the visitors with a simple penalty.
Glasgow kept the game deep in the opposition half for Parks to land penalty number three but Robinson reduced the margin two minutes later with his second penalty.
Parks replied again before another misplaced kick allowed Gloucester to attack and set up Charlie Sharples for the first try of the game.
Parks confirmed the dominance of the Glasgow forwards three minutes later with his fifth penalty and, eight minutes from half-time, a sparkling cross-field move saw Max Evans cross for a home try.
The break did not come quickly enough for a beleaguered Gloucester, who conceded try number two when Parks' long pass found full-back Bernie Stortoni to romp in for the score.
The conversion took Parks' first-half tally to 17 points and he made it 20 just three minutes into the second half with another penalty.
Gloucester tried to hit back but the home side soaked up all the pressure with flanker Peter Buxton and lock Dave Attwood driven back by ferocious Glasgow defence.
Kelly Brown and Richie Vernon led a couple of breakouts but Glasgow were pinned inside their own half, although they were content to keep Gloucester well away from the danger zone.
With ten minutes left, Glasgow again started to put pace on the ball as Gloucester ran out of steam and ideas and Parks banged over his seventh penalty.
