An interesting tip from Gary Volz of Cincinnati.
Since I don’t live in a particularly earthquake-prone area, I do not use museum gel, but I am aware of several collectors who do.

This word of caution from Cincinnati contemporary glass galley, Marta Hewett Gallery:

Museum gel and extreme heat. A recipe for disaster?

“We have had clients report coming home to find that in their absence a piece had “traveled” to the edge of its pedestal or onto the floor. When museum gel becomes extremely hot, either in direct sun, under intense light, or in an unairconditioned home, it may liquefy and cause the piece it is securing to hydroplane off its supportMarta Hewett

Tom Dimitroff of Corning reflects on the core issue of his article in Nat. Assoc. of Glass Magazine we reported on.

Thanks for the nice comments about my recent article. It is nice to remember that it was Corning’s cut glass industry and its need for high-quality lead blanks that brought Carder to Corning in 1903.

Then Marshall Ketchum comments on Moonlight.
As far as I know Moonlight is not dichroic. The formula that I have from Carder’s notebook doesn’t include Moonlight.
