Would injection moulded acrylic in grey/silver be an option.The brewerys always used to use em as promo/advertising in pubs? The range of designs n details you could do would be huge.Just my :2 to keep costs down. Good luck :tu
It's a possibility, but I would be very resistant to use any plastic's in an ashtray. Plus the mold setup costs a lot. Crystal cut glass would be a possibility, but expensive, and there are still some seams.
Also, this is something that could be made in China for cheaper, but I've got a thing for American made goods.
I do work in retail furniture and have a lot of experience with quality accessories. So work is a great place for me to look at finishes.
