Greg, you've got some serious misinformation there! I don't think Peter Layton was involved with the setting up of the Glasshouse.
I have the book from the exhibition "The Glasshouse and its Tree" here in my sticky little mitts, and I quote from the introduction by Sam Herman:-
"It has come to my attention that some people have incorrectly claimed involvement in the establishment of the Glasshouse. The only people actually invoved were Graham Hughes, Suzanna Robins, myself and a few of the graduating students who helped build the furnace and kiln. Hopefully, this will finally set the record straight."
I don't believe Peter Layton was one of those students - his name does not appear anywhere on any of the "branches" of the tree illustrated with all the appropriate names.
