<p>[QUOTE=&quot;Conder101, post: 2007190, member: 66&quot;]If you want high precision then yes it would probably be better done in a lab, but if you are just trying to get that first decimal place, that can be done at home without too much trouble.&nbsp; And in most cases that first decimal place is good enough.&nbsp; If you are trying to distinguish between two material that are similar enough that you have to go to two places or more you are probably in over your head anyway.[/QUOTE]</p><p><br /></p>
