The Cottage Glassworks of John McLachlan in Lambeth was founded in 1808, about the same time as Apsley Pellatt's Falcon Glassworks. Almost unknown until rediscovered here it was nevertheless of considerable importance. A commemorative goblet and advertisement by the firm are illustrated.
Another new glassmaker is Clayton Bros., known only by one marked jug which is illustrated.
We need to know much more about both factories. Check them out in Glasshouses/ Later and Peripherial Glass Houses and scrolling down.
