Synonymous with versatility and value, Wellington collection presents a fresh new look on the traditional shape and pattern. Wellington features a timeless appeal and boosts the brilliant clarity and substantial weight of the dishwasher-safe Crystalline. Crystalline is a term that refers to high quality glass, without lead content. The crystalline still has substantial weight and clarity, similar to crystal. In fact, when looking at the same piece, made in the 2 different materials, it is very difficult to tell the difference between them. However, crystalline is not acid polished, like crystal, as the acid does not favorably affect the crystalline, due to the lack of lead content. Therefore, crystalline (when cut) is flame polished, to clean the grey frosted cuts, to leave them clear and sparkling. This leaves the polished product looking very similar to crystal.
