And it's Frank's Ysart site. So is the main one, Scotland's Glass.
You will also find a lot of information, browsing here.
Nigel Benson gave a really interesting lecture at the Edinburgh conference on whether Ysart glass should be considered to be the forerunner of the Studio Glass Movement, the only thing that disqualifies it is being considerably earlier than that, because the birth of the Studio Glass Movement can be accurately pinpointed to the date of the Toledo Lectures.
The Ysarts were working with materials that were rather inferior to those availavle today, they struggled to find coloured enamels during/between the wars and even ended up grinding down celedon glass (that opaque pale green, used in kitchens and bathrooms) and scraping the surfaces of ceramic tiles to obtain some (this is why Vasart glass has duller colours than Monart or Strathearn) and they were working in an old draughty wooden shed, they had real troubles with controling the temperatures of the annealling ovens.
Because of the troubles with the ovens, many bits of glass have since turned themselves into crazed jigsaws. They do still hold together. Sometimes, damaged bits are well worth having, they're a lot cheaper than undamaged and still display well.
That's just a short potted resume of what I know, but I only flirt around the edges of Ysart glass and might not be overly accurate. My family collects it, so I
know it, in terms of seeing it, holding it and discussing it, but I don't collect it myself. I only have two bits. One is a jigsaw.
