Afraid I can’t find a burial, but in case you haven’t seen a report of the inquest ...
DEATHS IN THE LONDON HOSPITAL. – Last evening Mr. Baker held three inquests in the London Hospital. The first was on the body of Julia Sands, aged 66, a widow. It appeared in evidence that deceased resided with her son, at 26, Charlotte-street, Whitechapel, and that in the forenoon of the 31st ult. her son had placed a pot of resin to melt on the fire. When melted she went to lift the pot off with her apron, which catching fire, ignited the resin, and the consequence was, that her clothes were set in flames, which communicated themselves to the furniture in the room. Deceased ran into the street, and some neighbours extinguished the flames in which she was enveloped, by throwing pails of water over her. She was conveyed to that hospital, in which she expired of the burns on Saturday last. Her son, in trying to put out the fire, was so severely burnt as to be confined to the hospital for five days.
