what would be the best way of visualizing a print found on a glass bottle?\na ninhydrin\nb iodine fuming\nc taking a photograph\nd dusting with magnetic powder and lifting\nback
Answer
Brief Explanations:
- Ninhydrin is used for visualizing prints on porous surfaces like paper, not glass.
- Iodine fuming is an older method with limitations in clarity and permanence compared to other options.
- Taking a photograph alone may not enhance the print visibility effectively on glass.
- Dusting with magnetic powder is a good initial step as it adheres to the print on non - porous surfaces like glass. Lifting then preserves and makes the print more clearly visible.
Answer:
D. Dusting with magnetic powder and lifting
