This page shows the  'IZAL' pots originating from Sheffield
 
 
The disinfectant IZAL was discovered around 1885 following some analysis by an analytical chemist named J.H. Worrall who was based at an ironworks site in Chapeltown, to the north of Sheffield. 
A few years later a leading professor from Bartholowmews Hospital confirmed that the product was free from toxic side effects and the product then became a commonly used ointment for the treatment of dysentry. 
The name IZAL is believed to be an anagram of Liza, a favorite sister of J.H. Worrall.
 
Two variations exist for the green print IZAL pots, which pots are printed on both sides.  
One variation states the price of 1/1½ and has the word INVALUABLE, whereas the second variation has the word VALUABLE and does not quote a price. 
The pots are 60ml in size, which is marked on the underside.

The 'Valuable' type pot also shows the company title as being 'Ltd'.
