This jug is made of cream coloured urea formaldehyde, and decorated with Kelvinator's trademark helmeted head. Encouraged by the success of phenol formaldehydes such as Bakelite, alternative resins were sought by scientists.Thiourea-urea-formaldehyde was developed by Edmund Rossiter in 1924, and by 1929 urea-formaldehyde had improved properties. Urea-formaldehyde resins allowed a wider range of colours than the earlier phenolic resins, including light, bright colours and so became popular for crockery and picnic sets.
