 Welcome to a new precious plastic video So in this video, we're going to show you a new kind of way how to work with plastic Usually plastic is all processed in machines and very big quantities, but this is more of a Croftmans way of working with plastic to really Do it by hand sanding with using very basic tools just to make something very small and precious and delicate and Mahta from Spain is going to show you how that's being done. Hi in this video I'm going to show you how to make a ring out of polystyrene Once the mold is inside the oven It should remain there for 20 minutes Okay, so at this point of the process, this is what we should have a polyester and tile with the smooth waters ready to become ring and What we are going to do next is I'm going to show you How to choose the best spot on the tile for making the ring Then we're going to drill a hole according to the size of our finger and finally We're going to shape the ring around it Once we have the tile and before starting to shape the ring It is very important to choose where to do it So for example if you want to make your ring more special or precious It is nice to take a look to the tile searching for areas that can make a ring look more Precious because of transparencies or color or colorful spots like this blue or this green one and Then once you have it start to shape the ring there. So for instance, I'm going to continue doing it like here We should have something like this a Basic and rough shape which we will sand and polish until we get to something our final ring So sanding It's one of the most important part of this whole process because as I said before it will determine the final quality of our product Fortunately PS it's one of the few plastics that can be sanded and polished with really good results In this case, we are going to use four different kind of paper and we are going to go from a thicker one 240 to a thinner one 2000 we start with P 280 sending the edges of the piece and shaping the ring as we like As this is the thickest of our papers we will use it to perfection the shape of our ring Sanding the exterior of the ring is very important, but getting a good quality on the interior It's even more crucial as it needs to feel comfortable for the finger. We continue with P 600 Doing exactly the same As we sand we can already see how the surface quality improves The third paper is P 1000 The last sanding paper before swapping into polishing is P 2000 After it the surface will start feeling nice and shiny There are a few ways of polishing plastic and so far these are the ones we've tried toothpaste car paint cleaner and car polish both toothpaste and paint cleaner work and Leave a shiny surface Problem is that we did a manual compression and that always leaves some holes on the surface And these holes get filled with the liquid which isn't transparent. That means these holes become white spots all over the surface So at the end what worked best for us is this We are car polish we found in the workspace because it's transparent, which means We don't have white spots anymore, and it also leaves a really good and shiny surface at the end We have this ring shiny and nice But we don't have to forget about Marking the type of plastic it is so we are gonna do it with with the dremel, but you can also do it by hand Okay, so now we already know how to do this string but you could also Play a bit more with the shape and getting other kind of rings for example We have this one quite simple and you can go also for a more complex one if you go if you want another option is Swapping into other kinds of jewelry as this bracelet for example transparent and nice or this This necklace in which we really put an effort on On getting it shiny so you can really see see it as a stone Another possibility would be not only using the plastic on its own But combining it with other materials like metal or you can also do it with woods whatever you you want to and At the end you can also Try different melting temperatures so you can Have a little spots in which look super rocky and nice And well, that's what I did with two kinds of plastic transparent and black but imagine what you could do with More colors. I mean the possibilities are amazing All right nice So yeah, that was it for this video if you have any questions feel free to post a topic in our forums and Share as a picture of the things you made
