Hi, I followed a tutorial on YouTube, but I don’t understand why when I add light, the red color disappears and only white remains. Does anyone know why and could explain it to me? Thank you so muchhh. I followed this link: https://youtu.be/J7DQHmIBN6E?si=FcauufwcwWIUeH2s
Hi everyone, I have an assigment about fabric identification. I did all the test like staining test, wicking test, dropping test, burning test, microscopy. But now the result is conflicting so I cannot recognise what this fabric is. Can anyone expert in this field can help me please 😭 I would put all the result of my test in here: (the first picture is the sample I need to identify). I also put the guide of my experiment behind each result picture. With the solubility test, the result is my sample completely disappear. Thank you!!
