Images of a north London flat prosecutors say was used as a "bomb factory" by the alleged 21 July bomb plotters were shown at Woolwich Crown Court. Six men deny the charges.
The jury was shown a picture of a bottle of liquid peroxide. Prosecutors say police officers found numerous bottles of peroxide bottles, some full, some empty, at the London flat.
One of the images shows the residue of a yellow substance on a furniture unit, which prosecutors are linking to the alleged rucksack bombs.
The jury was shown a photo of a cooker. The prosecution says evidence includes "corrosion" on the cooker's control panel and peroxide traces on a saucepan and frying pan.
One of the alleged plotters, Yassin Omar, lived at the flat and the court heard his fingerprints and those of several other defendants were found on bottles and boxes of peroxide.
A photograph of a five-litre glass laboratory bottle was also shown to the jury.
