Why is it called Lampworking?

Lampworking, also known as torchworking or flameworking, is an old glass technique probably dating back to the fifth century BC. (according to Wikipedia: https://en.wikipedia.org/wiki/Lampworking) Previously it was done using the flame of an oil lamp, with the artist blowing air into the flame through a pipe to melt the glass in order to form it. Now torches are used that burn propane, natural gas, or butane. I'm not aware of anyone who still uses an oil lamp (although undoubtedly there will be someone who does and proves that I'm wrong,) but the term lampworking persists.
