A few things need to be clarified:
The fact that the Diary could have been aged artificially means that it cannot certainly be said to have been 80-90 years old based on Voller's examination. The factual issue of whether the Barretts had access to a sunlamp and had been told how to artificially age documents is neither here nor there bearing in mind that both things are possible and thus cannot be ruled out. As I (and others) have had cause to say before, absence of evidence is not evidence of absence.
Unfortunately Voller did not write a report but in the transcript of his meeting which we have finally been told today (and no, we were not told before today) occurred on 20th October 1995, he said the fading in the diary was "characteristic of some considerable age" but he also said that the bronzing that he saw "tells me it is genuinely old".
Although we are told (yes, told!) by the Chief Diary Defender that "Voller was talking about the fading in the diary, in connection with the sunlamp" this is not something that Voller himself says in his letter to Nick Warren of 8 February 1996, which I have already quoted from at length. In that letter he says that his opinion that the Diary was written 80-90 years earlier was "on the basis of appearances" (i.e. not specifically fading). He said he was asked if "such an appearance" could be simulated by a forger and he said that it could be done by an accelerated fading apparatus. He says that such an apparatus will "simulate the effects of five years exposure to sunlight in a matter of weeks". The only specific mention of fading is in respect of uneven fading when he says that used by an amateur it could produce "exactly the sort of uneven fading that is characteristic of old documents".
Now, as I'm sure the Chief Diary Defender knows, some formulas of iron gall inks result in writings that can turn brown quite rapidly through exposure to sunlight. In other words, sunlight can mimic the effect of oxidization of ink. So, while I can't say what Voller was thinking, I have to take into account the possibility that he was saying that the appearance of the Diary which caused him to think it was 80-90 years old included both the fading and the bronzing and that both effects could be produced by an artificial fading apparatus or UV sunlamp.
Either way it doesn't really matter because from viewing a colour photocopy of Nick Warren's 1995 test sample (and I believe it was a high quality colour photocopy obtained by Harris, not just off an ordinary machine), Voller said this in 2001:
“…the poor opacity and fading and bronzing that are apparent in your copy of Nick Warren’s letter. These are aspects that can be drastically influenced by relatively small shifts in the conditions…One factor that can strongly affect both the initial result and the subsequent behaviour of the ink, is the choice of paper and it may perhaps be that Nick’s choice was not such as to bring out the best in the ink…I agree that the ink of Nick’s letter has taken on an appearance similar to that of the Diary, as regards fading and bronzing…”
What I understand Voller was shown was a colour photocopy of Nick Warren's 1995 test sample which was made in 1998, i.e. three years after the sample was written, i.e. exactly the same number of years after 1992 when Voller examined the Diary in 1995. This colour photocopy (i.e. from 1998) is what I have already reproduced in this forum.
Both the fading and bronzing, therefore, appear to occur naturally in Diamine ink after only a few years and would have fooled Voller.
Yes it was a colour photocopy not the original but we're not doing a precise scientific experiment here. We are simply trying to get to the truth and the colour photocopy is good enough for our purposes. Voller certainly had no objection to it and felt able to express an opinion in writing based on viewing it.
The Diary Defender tries to play dumb about the fact that the nature of the ink can vary according to the type of paper used as if that helps her cause. The simple point is that Voller could easily have been fooled and his conclusion that the Diary was written 80-90 years earlier than his examination now has no value. Moreover, and crucially, it would seem that the Diary could have been written with Diamine ink because it exhibits similar characteristics to Nick Warren's test sample.
