@sangesh @RacunCintaaMu The stain consists, assumingly, of oxidation products of other substances that are contained in the tissue. It is not only cellulose that makes a tissue. These tar like stains are products of an incomplete oxidation. Just like crock but with a more sticky oily texture.
@GrinvaldEran @RacunCintaaMu If I was only paper, the weight wouldn’t go up past the initial weight. The cellulose of the paper burns (an oxidation) and the product is CO2.
There must be something on the scale that binds O2 and stays on the scale.
@RacunCintaaMu Why I think there is iron involved? Look closely the „running sparks“ near the end, right before the weight goes up, are typical for burning iron wool.
@RacunCintaaMu I assume we do not see all that burns here. First the tissue burns producing CO2, which evaporates, hence the loss of weight. But then the iron wool, that is hidden in the tissue starts burning. The product here is Fe2O3 wich is heavier no evaporation. Hence weight goes up.
@AmoebenTranspor@lu_eder Er meint Haftlinger! Das ist ein Kompositum aus dem Substantiv „Haft, die“ und dem englischen Verb „to linger“, was mit verweilen übersetzt werden kann.
The 23-minute D-Day landing in Saving Private Ryan (1998) cost $12 million, about a fifth of the film’s budget. Filmed over a month with 1,500 actors and 400 crew, it remains one of cinema’s most intense sequences.
