My collection is primarily English and Bohemian (Czech) in origin, but beyond that, attributing makers has really been a matter of going with the majority online opinion. For example, most of my "English" glass has been attributed to Stevens and Williams, both in books and online. There are differing opinions of course but for the purposes of this collection I am going with the general consensus for glass of various types. I am not claiming to be correct, only that my attributions are those most commonly found.
