You can set up a retail account using a few of the same glass supply companies with which retail stores set up their wholesale accounts. Most require credit cards to invest in your purchases if you order by phone from their glass brochures. Some allow you to pay by check, but wait till the check has been actually cleared before they ship your glass purchase.
Glass magazines are complete of promotions for glass providers or you can research on the internet. The magazine ads and articles also show images of a few of the glass available so you obtain a suggestion of what the various sorts of glass look like. The glass suppliers' catalogs have color images of all the glass and colors they supply. The only issue is that you just can't attain a true feeling of the glass and see exactly how it seems with natural light looking at it.
You can buy the majority of the glass supply you require through a local retail glass store. Some will exclusive order glass for you, but do not be surprised if a small shop manager can not support you by very special ordering a piece glass. Wholesalers need them to meet minimum dollar amounts and the smaller glass shop or store owner most likely will not be able to satisfy that minimum based on your needs, alone. Glass Company with a larger client base will put glass orders more regularly. You may have to wait until the shop has a large enough glass supply purchase.
Glass changes in structure and sizes. Your supplier may not be able to match additional glass supply; so, purchase all the glass for your task all at once.
