What is wrong with a bit of primitivity in glass, Mexican glass is not bad per se, I have some Mexican glass in my collection. You get seed bubbles in some of the finest glass but yes it is often a feature in countries that are not very wealthy, the glassmakers have to be more efficient to survive and use glass that a lush company might be able to afford to just throw away.
In another thread we have a piece of art glass that has been made recycled glass. There is often a snobbery associated with a glass origin but then there are many others who find that the social story that the glass can tell is as fascinating as the handful of names that can produce the ultimate it technical sterility

or perfection. My preference is more for a piece of art glass that imparts the feelings of the maker or useable glass that is the right shape, size and weight for comfortable use.
Ysart Glass is in many respects a very primitive glass and invariably contains not only seed bubbles but other contaminants in the mix.
Likewise when we deal with people from different countries and communicate in one language, English - that for many members is a second language the we must apply tolerance to interactions. It is of course inevitable that people will get irritated with each other, but just concentrate on the glass not the people please. We are a serious board interested in expanding and sharing knowledge of glass.
