How do I identify Czech glass?

To identify Czech glass, first see if your piece bears a foil label or an acid mark that signifies the maker. If you find one, search trusted resources to determine who the maker is and if the company is Czech. Some well-known Czech makers include Moser, Crystalex, Rückl and Škrdlovice. Unfortunately, foil labels on older Czech glassware may be lost, making it difficult to identify. As a result, experts recommend that you consult a certified appraiser or knowledgeable antique dealer if you can't locate a marking or label or want further support with identifying your piece.
