Sunlight on mirror causes fire in Chalfont St Peter
Sunlight reflecting off a mirror caused a fire which damaged a house in Buckinghamshire.
The fire service has urged "extra care" with mirrors after the blaze in Chalfont St Peter on Thursday.
A mirror on a chest of drawers concentrated the sun's rays on to a curtain, which started to burn, the fire service said.
The fire spread to a cabinet and caused smoke damage to about half of the first floor of the two-storey house.
Watch manager Sam Sansom from Amersham fire station said: "We are advising people to take extra care, particularly with convex and concave shaving or make-up mirrors.
"Keep them out of contact with direct sunlight, and never put them on window sills."
