There was not a central clearing house for glassmaking techniques in the past but today with the web it is feasible. It is only in the last 10-20 years that 'well' researched books on glass for have really surfaced although poor efforts do still surface. The web and networks like the GMB give no excuse for sloppiness today.
However, that does not mean that it can lead to definitive usage of a term, but what can be achieved is a bringing together of technique names and in time evolve where the earliest to latest uses of a term are referenced. This might not lead to a change in usage but it could give researchers and historians a centralised reference. That in time could help to reduce confusion for collectors who will have adopted terms from different sources. Most on-line references, but not all, fall down in settling for a single use of a term and not giving sources. Starting point must be your own knowledge and defining where you learned that, then those of your peers in the industry. For example Alastair could be a useful sounding board. Then add-in and cross reference all the published definitions. After that contacting as many Venetian glass-makers to get their input. In parallel bringing those terms, that you discover being used oddly, to places like the GMB to get a random feedback sample.
