Dear Trude, At the National Museums Scotland we have treated 3 pieces of contemporary designed Murano glass vases designed by Michele de Lucchi for Memphis, Milan, and made by Toso Vetri d'Arte, dating from 1983 which have shown evidence of weeping and formation of salt crystals. The pieces are on display , we washed the glass to remove surface salts and dried them. and have displayed them at 40% RH using passive control ( conditioned pro-sorb cassettes). The vases have been on display for 4 years , we continually monitor for signs of redeveloping weeping but as yet not observed anything . The glass is coloured , predominantly blues, greens and yellow.

The work is from 2011 and I would be interested to hear if anyone else has found Murano glass which as recently been produced to be weeping, and what the maintenance implications have been. ------------------------------ Trude Ellingsen Objects Conservator National Gallery of Victoria Melbourne +61 3 8620 2108 ------------------------------ Reply to Sender : https://community.culturalheritage.org/eGroups/PostReply/?GroupId=481&SenderKey=0b328e7f-0c86-4fc6-b297-8cdc0a659155&MID=9030&MDATE=756%253e465469&UserKey=d16eaa87-0f69-494b-9f2f-303dbc1222e1&sKey=fab9aa4f27a04c5d876e Reply to Discussion : https://community.culturalheritage.org/eGroups/PostReply/?GroupId=481&MID=9030&MDATE=756%253e465469&UserKey=d16eaa87-0f69-494b-9f2f-303dbc1222e1&sKey=fab9aa4f27a04c5d876e You are subscribed to "Global Conservation Forum (ConsDistList)" as [email protected].
