How to distinguish between real EAPG & repros?

My mother had a large collection of daisy and button glassware, which I know has been reproduced a lot over the years. I think most of the pieces are original EAPG, but some may be reproductions.

I have multiples of some pieces that are the same size and shape but some have sharper edges than others. Are less sharp edges likely to be repros? Or do some original EAPG pieces also have smoother edges? Are there other ways to distinguish between the older and newer pieces?

Any perspective would be very helpful!

 

Think we will need pictures of the ones you are in doubt of.

Many companies made variations of the daisy and button. That could also be the reason for the sharpness differences.

 

There is no easy way. Most of use use books to check or look under motifs here.

Even the most experience sometimes have trouble

 

Did different companies ever make molds in the same exact size and shape as another company's molds?

I know sometimes the molds were sold. Other than color differences, could the results be different when the same molds were used by different companies?

I don't have photos yet, but will post them when I do.

 

Thanks for the link, George. I didn't know there was such a comprehensive free site. A number of years ago I saw there was a paid site but didn't spring for it.

I want to be honest with buyers, but not sure what to say if I know a piece was reproduced but I don't know if mine is original or a reproduction?

 

Also, I meant to ask if weight can be an indication? If you have two pieces that are the same shape and size but one is heavier, does that tend to mean it's older?

 

Sadly, Pat, there is no easy way. I started in the mid 1960s trying to learn about glass, I found that the more I studied, the more I realized i had more to learn. There are no generalities that are always true. Except maybe "if the glass feels greasy, or smells of vinegar it's not old."
Molds made in 1880 wore out and new ones were made, all by hand, so they coulndn't be exactly the same, but both are 130 or so years old.

 

Thanks, Cherryhill. It sounds like I shouldn't give myself a hard time for what I don't know... which is a lot.

Interesting point about molds being remade which I hadn't thought about.
