I have had someone recently asking me about Iwata Glass and why it's worth so much. The easy answer is that people want it. However I find lots of Iwata Glass sold as artist pieces, when the truth is most of it is production glass. That means, like any glass company, the piece was designed by someone (in this case Toshichi Iwata) but was made by whichever glass blower was employed at the time. That might be an Iwata, but just as likely to be one of the many artisans that worked for them.
How do I know what is a production piece and what is artist made?
Any stickered Iwata is production. If there is no sticker it comes back to what comes with the vase, and the work involved in it.
Artist pieces should have a tomoboko with them (wooden box, artist signed), should have an artist bookmark, and will often be a very different and complex work.
Japanese art glass is rarely signed, particularly if it is prior to around 1990.
This is a production piece. Lovely, well made, but does not carry the cachet or price than an artist piece will.
