I have just got the first glass prototype and will try it out. Some refinements need to be considered and will post a picture or two once I have a set that I am comfortable with it. I must say that glass feels good; looks good and the glass makers can make all kinds of piping objects.

Someone mentioned about a mass order, unfortunately making 10 sets is ten times the effort of making 1 set. The only economies of scale that I could see would be a MRT ticket or two. Price is still too high and will post that once it is confirmed & reliable.

I am also trying to find an acrylic tank maker who is willing to have a go but still focusing on finding a plastic bottle manufacturer to make an injection molded version. If anyone has any contacts let me know?

Thanks
