]]>I’ve gotten some informaton about PC-TEA developing times from a lab in China (where I live). At 1:25 dilution, use the same times as D-76 stock. At 1:50, use the same times as D-76 1+1. At 1:100, use the same times as Rodinal 1:100 or just general (semi) stand development.
]]>Bonjour et merci pour votre commentaire. En effet, j’ai écris cet article il y a quelques années et l’obturateur est encore défectueux. C’est une vrai galère à réparer et on se pose sans cesse la question de la fiabilité quand on l’utilise. Au passage, votre article est extrêmement complet et détaillé ! Il donne une bonne base de décision sur l’achat potentiel d’un Flexaret.
]]>@ Harold Klee: Boiling point for TEA is appr. 335*C (635*F), so reaching 250*F is not a problem (unless, of course in a waterbath…).
However, it is desirable to keep the temperature to a minimum needed to dissolve phenidone and asc.acid. Higher than nescessary temp is likely to affect the ‘longevity’ of the mix….
If heating in a waterbath: TEA (as well as glycol) is somewhat hygrosopic (absorbs water from the air). Keep the bottle closed, and dry it off before opening! Any water into the mix, and the keeping properties definitely will go down.
@ Pierre Killmayer: Thank you for a very nice article!
