Check washing process of washing a check is relatively simple and can be accomplished with basic solvents. The actual solvent is largely irrelevant — more importantly, the polarity of the solvent must match the polarity of the dye in the ink. For example, an ink that is mostly made of a polar dye would require a polar solvent (e.g. acetone or isopropanol). Both nail polish remover (acetone) and rubbing alcohol (isopropanol) are able to pull most common inks away from paper in minutes. Similarly, a non-polar dye would require a non-polar solvent (e.g. toluene or a similar hydrocarbon). Check washing Check washing
Pear drop Pear drop A pear drop is a British boiled sweet made from sugar and flavourings. The classic pear drop is a combination of half pink and half yellow in a pear-shaped drop about the size of a thumbnail, although they are more commonly found in packets containing separate yellow drops and pink drops in roughly equal proportions. The artificial flavours isoamyl acetate and ethyl acetate are responsible for the characteristic flavour of pear drops: the former confers a banana flavour, the latter a pear flavour. Both esters are used in many pear and banana flavoured sweets. However, a natural pear-derived
