Hi Steve
Welcome to RootsChat

His death in Shettleston in 1856 showed him aged 50.
Have you found him on the 1851 census? There are few entries, any age, for someone with that name. The closest in age that I could see in 1851 is this entry:
Dennis Bryce 50 coal miner b. Ireland
Cathrine Bryce 40 b. Ireland
James Bryce 20 coal miner b. Glasgow
John Bryce 18 coal miner b. Glasgow
Thomas Bryce 10 coal miner b. Gorbals
Dennis Bryce 5 b. Gorbals
Address B Penders Row, Baillieston, Old Monkland
