My teacher this year assigned us to do an alum crystal growing lab by ourselves, so we find the procedure and do a related theory all by ourselves. In my group i was doing half of the related theory and i basically had questions i had to answer. The question i am stuck on is, "5. Once the crystal is growing, it may be a good idea to "clean" the monocrystal surface. Why is this important? And how does one "clean" the crystal?" I know it is important because if i dont do it the crystal will continue to grow on the imperfections and make them more promenant and harder to remove. I also figured out what to look for when cleaning the surface and what to do, Each time the solution is saturated, it is a good idea to "clean" the monocrystal surface, by - making sure the crystal is dry, - not touching the crystal with your fingers (hold only by the suspending line if possible), - removing any "bumps" on the surface due to extra growth, - removing any small crystals from the line. The thing i dont know is the 'how' How do i clean the surface, what do i use to remove the bumps. I was thinking something like a toothpick or a q-tip thats been dipped in 60C water so that when it touches the bumps it dissolves them. Is there any advice, does anyone have the answer?
