The "picture branch" of Boulton's business was discontinued as unprofitable, the loss on this and the japanning trade being over £500 for 1780. The partnership between Eginton and Boulton was dissolved.
Lord Dartmouth proposed to grant Eginton a government pension of £20 a year for his work on the picture copying process, but Boulton raised objections and the offer was withdrawn. For the next year or two Eginton appears to have continued to work at Soho, and to have begun in 1781 to stain and paint upon glass. In 1784 he left Soho and set up in business for himself at Prospect Hill House (demolished in 1871), which stood just opposite Soho. Before Eginton the art of glass-painting had fallen into complete disuse. He revived it and turned out a long series of works in stained glass from his Birmingham factory. His first work of consequence was the arms of the
knights of the Garter for two Gothic windows in the stalls in
St. George's Chapel, Windsor, and his other works include: • The windows of
Merton College chapel, Oxford • The ante-chapel of
Magdalen College • The east window at
St Paul's Church, Birmingham, where Boulton had a pew. • The east window at St Alkmund's Church,
Shrewsbury. Eginton painted a window (20 ft. by 10 ft.) representing Solomon and the Queen of Sheba, in the banqueting room of
Arundel Castle, and did a large amount of work for
William Beckford at
Fonthill Abbey, including thirty-two figures of kings, knights, etc., and many windows, for which he was paid £12,000. Much of his work was for export, and some of his best work ended up in
Amsterdam. In 1791 he completed what was then considered his masterpiece, the "Conversion of St. Paul", for the east window of
St Paul's Church, Birmingham, for which he received the "very inadequate sum of four hundred guineas". Eginton's works were, in fact, transparencies on glass. He was obliged to render opaque a large portion of his glass, and thus covered up the characteristic beauty of the old windows. Eginton's showroom was visited by all distinguished visitors to Birmingham.
