New Member - First Silly Question!
« on: January 12, 2012, 10:25:54 AM »
Hello.  We've always loved 60's Murano glass and we're starting to collect better items in a more planned way.  My question - is it safe to display glass on a sunny south-facing window ledge?  Can the sun fade or damage glass?  Thanks in advance for any advice.

Hi and welcome Mr. Loco!  :hi:

Personally I´m always a bit cautious with displaying glass on a sunny window sill although it´s such a fascinating
thing to see your items in the different lighting situations.
For the following reasons:
- clear glass can change the colour over the time. Some glass becomes slightly yellowish or greenish and over a
  longer period purple-is; I´m not sure about the first two effects, but the latter is caused by the manganese
  content in the glass batch.
- some glasses can work as a lense - especially paperweights - and even cause burning. I think we´ve got a topic
  about an article in some newspaper some time ago.
- the heating when exposed to the sun can cause stress fractures, if the annealing wasn´t sufficient or there
  are still strains within the glass. Bubbly items are even more endangered because of the different extension
  levels of glass and air.
I therefore tend to keep my better pieces north and some of the minor and coloured ones south...  :)
Surely others will be adding quite a bit to your thread.

Kind regards,
Dirk

Don't forget that the advice from Dirk applies only to the Northern Hemisphere Jakgene and myself would use the Southern window sill.

Hi Mr. Loco.

Welcome to the mad world of glass collecting and the GMB.

I am posting a picture of my South facing windowsill so you can see how the wood nearly caught fire by sunlight through the glass spheres I originally had displayed there!!

Eeeek!

Hi there and Welcome!!   :rah:

No question is ever Silly in my mind, as we are all learning!! 

I never knew that about glass either in the window sill as posted here.....so any questions are Good questions, IMHO.  It is all a learning process!!

Sounds to me, Mr Loco,  like you have a collection we would all like to see - at least some of the pieces you like.  This  link http://www.glassmessages.com/index.php/topic,42591.0.html takes you to a wonderful topic that many people have contributed to and I suspectryou could enrich by showing us parts of your collection.

In future it would be better to place general questions(like this one) in the "Glass" section of the site as a person with no real interest in Murano(Yes!  There are some out there.) who might have helpful suggestions would not see it.  The moderators will fairly rapidly move a topic to its appropriate area if it is very specific and is not creating enough interst in the general area.
