Dear all,

quote from Tom, Feb 2,
I totally agree with your logic for buying modern equivalents where the old examples are beyond reach price-wise. I did exactly the same with overlay glass bottles. The only problem is that at least 50% of them began to crizzle 3-4 years after I bought them.

Interestingly, when I met up with Inn Bok in Bangkok a couple of weeks ago he mentioned the same problem, and had an intriguing explanation for it. But I won't steal his thunder - better let him tell the story.


During the meeting with Tom in Bangkok, I mentioned what I thought could be the reason for cracking / crissing of bottles. I suspect that these bottles developed in Hebei in the 80's did not have the proper ' curing / cooling '. In metallurgy, the equivalent is known
as ' annealing '. The impatient bottle makers cooled the bottles too fast, resulting in in-built stresses that manifested some years later
in signs like ' kami-kase ' across the entire body of a bottle or snow-flakes, etc. Some of my overlay bottles I bought in the late 80's
gave way a few years later.
