<p>[QUOTE=&quot;cxgirl, post: 10316103, member: 63&quot;]nice pieces of glass Marote, they look antique to me<img src="styles/default/xenforo/smilies/smile.png" class="mceSmilie" alt=":)" unselectable="on" /> I don&#039;t know if they make glasses with a needle etch design anymore, when I see them I always think old. I seem to think Manganese only reacts to a 365nm light, under a 395nm there is no glow (it has been a bit since I&#039;ve thought about glowing glass, so I could be remembering this part incorrectly).</p><p>The large glass appears to glow brighter, which goes with it having uranium in it, the glow in glass with Manganese makes me think of Granny Smith apples, a lighter glow. Manganese is also in coloured glass and will glow different colours.</p><p><br /></p><p>the link below is interesting<img src="styles/default/xenforo/smilies/smile.png" class="mceSmilie" alt=":)" unselectable="on" /></p><p><a href="https://www.barnesandbridge.com/general-7#:~:text=Uranium%20can%20be%20found%20in,green%20as%20Uranium%20glass%20does" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.barnesandbridge.com/general-7#:~:text=Uranium%20can%20be%20found%20in,green%20as%20Uranium%20glass%20does" rel="nofollow">https://www.barnesandbridge.com/general-7#:~:text=Uranium can be found in,green as Uranium glass does</a>.[/QUOTE]</p><p><br /></p>
