Do you have many glass books? That's really what you need...and it will stop you wasting money on glass that perhaps isn't worth it and give you knowledge to ferret out those special pieces of art-glass that we all love.
I know that collecting glass is like an addiction (see my shed containing my mistakes for details!) but it really is best to learn as much as possible before you buy.
Maybe you both do have lots of glass book, but if you don't, simply start a thread in the
Cafe Forum telling us what sort of glass you like and we will happily make suggestions of appropriate books for you.
If you would like a look at our general much-loved book list, you can find it here:
