, but Boyle saw the residue in the broken container glowed faintly, so they were on the right track. Godfrey's job became making phosphorus for Boyle, and he acquired skill at it. His procedure was the same as Brandt's, namely to boil human urine down to a residue, then heat that strongly to give off phosphorus gas which would condense. Godfrey produced two forms, solid phosphorus (the white phosphorus allotrope), or a mix with oil of urine where it remains liquid at room temperature.

Godfrey was not always careful handling phosphorus, his fingers were often blistered and slow to heal from touching the solid. On one occasion on his way to see Boyle a phial of phosphorus broke and burned holes in his breeches, which Boyle "could not look upon without some wonder as well as smiles".

Initially Becher and Godfrey had got along well and they shared lodgings in Covent Garden

. When Becher's wife arrived in London it seems she took a dislike to Godfrey and there were various disagreements. Godfrey helped the Bechers move to new lodgings, yet Mrs Becher would return to shout abuse and accusations. The worst was when Boyle reduced Becher's salary over lack of success in Becher's alchemical experiments. Becher blamed Godfrey, and Mrs Becher took to following Mrs Godfrey through the streets shouting abuse. But, as Godfrey wrote, "thank God, all in German, that the people understood her not."

By 1682 two years of research had satisifed Boyle's curiosity and Boyle and Godfrey parted. Godfrey was still interested in phosphorus and Boyle helped finance Godfrey's manufacture of it. In 1683 Godfrey named his first son Boyle Godfrey, in Boyle's honour. (He had two more sons, Ambrose and John.)

By 1685 Godfrey had a going business. He had a furnace behind his lodgings and made use of the human wastes from the adjoining Bedford House estate. He advertised phosphorus at 50 shilling

, where in time he became master of the laboratory.

Others tried to make phosphorus too, without success. It was supposed there was a step missing from what Boyle had published in 1682, a step only Godfrey knew. Godfrey had every reason to keep his methods secret, but the essentials were exactly as Boyle had set out. The only extra thing Godfrey knew was that faeces could be used as well as urine.

Godfrey's business grew along with his reputation, and he took on employees, becoming known for producing the best phosphorus available. He sold within Britain

. By the early 18th century, Godfrey was thought to be selling as much as 50 lb a year, worth about £2,000, or about £600,000 in today's money. This was not his only business, but presumably the profit from such a turnover was significant.

In 1707 Godfrey was wealthy enough to buy the lease to a new shop in Southampton St where the Bedford House estate had stood. He opened a pharmacy

, and he and his family lived above it. Under the lease he could not carry on "obnoxious" trade there, but the narrow strip of land behind was unrestricted, so he built a workshop there, where he and his staff made phosphorus, and where he gave demonstrations of it.

Godfrey died on 15 January 1741 and his oldest son Boyle Godfrey took over the business. But Boyle dabbled in alchemy, wasted his inheritance

 provided by his brothers Ambrose and John, who took over the business in 1742. Ambrose and John were also unsuccessful and in 1746 were declared bankrupt. The business passed to their nephew, Boyle's son, named Ambrose Godfrey after his grandfather. The younger Ambrose was successful, carrying on the business until his death in 1797, when it passed in turn to his son Ambrose Towers Godfrey, who formed a partnership with Charles Cooke

. The firm Godfrey and Cooke continued until 1915.

But the Godfrey business' dominance in phosphorus did not last. It was overtaken by new methods such as that of Bertrand Pelletier using bones in the 1770s.
