BuckeyeCoinGuy Pillar of the Community United States 711 Posts	Posted 08/11/2015 3:51 pm Does it sink in water or float? If it floats (without an air bubble), it is not PVC. If it sinks, it may be PVC. If it sinks, light it on fire. If the flame has a green tint to it, has an awful smell (hydrochloric acid), and leaves a burnt char, it is most likely PVC. If it drips, it is not PVC. Report this Post to the Staff

BuckeyeCoinGuy Pillar of the Community United States 711 Posts	Posted 08/12/2015 9:35 pm Just make sure that it isn't an air bubble floating it. When doing a specific gravity / density / floating test in the lab, we generally submerge it in tweezers and then shake it out. You need to make sure it submerged and doesn't have a bubble, but if you do that and it floats, it can not be PVC. In hindsight, maybe saying it as 'if it floats, it isn't PVC' isn't the best way as you could have a surface tension thing going on. Probably a better way of saying it would be if you sink it and it rises to the top without the help of an air bubble, it isn't PVC. Report this Post to the Staff
