Title: 'Muffled' glass: is this 'mould-blown' glass?
Post by: David E on August 06, 2006, 08:41:37 PM

I have come across a reference to 'muffled' glass that appears from the described process to be the same as mould-blown glass. Can anyone confirm?

Muffled glass was apparently invented by a German firm called Berlin Company(?) in 1884 and I believe patented by them - does this tally with the production of mould-blown?

David -

Could this refer to irridescent glass produced in a muffle furnace? Good discussion here -

Hi Connie: no, I don't think these are related. Muffled glass has a  texture but no iridescence.

See: Birmingham Glass (http://www.birmingham-glass.com/index.php?main_page=index&cPath=10&zenid=0fc1974e90ddd5da89d2ba20a405abd5) - images need severely optimising, but they are based in my home city so I'll contact them to see if they can help.

I did think at first this could be related to Whitefriars and Webb's 'optic-moulded' vases, but perhaps not.
