So the next thing to find out is who or what Thorneycroft of London was - and if they existed.
For a London glassmaker, perhaps our Adam Aaronson might know?
It's not a name I'm familiar with and it is not mentioned anywhere on the chart I have depicting the Glasshouse history.
In the early '70s, there were students from America who came and worked at the RCA, a few of us have pieces by Wayne Filan - a visiting student, circa '71.
Silver salts were used at the RCA.
