There has been a microscopic examination of the parchment. Posted on the Sinaiticus website.
Yes, read the lines, and between the lines.

Parchment Assessment of the Codex Sinaiticus

Gavin Moorhead acknowledges the colour difference of the British Library and Leipzig sections.
We can run through the ink section later, it was fun going back over this amazing page.
"next to nothing is known about the parchment used for the Codex."
"Overall, the condition of the parchment is
exceptional for its age."
"Low in levels of significant degradation."
"The parchment is .. Supple and flexible in quality."
What can be said with certainty is that any 4th Century parchment with this amount of flexibility, thinness, maker’s holes, repairs and striation is
exceptional. It remains indeterminate how these features came to be or how the making process and rigors of history have impacted on the longevity of the parchment.
What can be said with certainty is that
any 4th Century parchment with this amount of flexibility, thinness, maker’s holes, repairs and striation is
exceptional.
New parchment can be near white but as it ages or is exposed to detrimental factors it will start to yellow and go brown-black if left to degrade completely.... Only a few folios in the codex could be considered to be heavily discoloured and these tended to be the folios that were once adjacent to missing parts and therefore, more exposed.
Opacity values for the codex did not vary significantly and tended to reflect thickness variances
rather than increased degradation.
Apart from a small percentage of folios with heavy ink corrosion, most of the folios appeared to have survived the rigours of 16 centuries with an
unexpected lack of damage, suffering in the main only from small tears and losses along the head, tail, fore-edge and spine folds. Much of this damage is more likely
attributable to mechanical damage than physical deterioration.... the minimal damage and good condition
"the parchment is extremely fine with
relatively few extant imperfections and markings"
"low incidence of follicle, axilla and scarring evidence"
the relatively small amount of ink corrosion and brittleness
Most of the scarring is small in size and tends to occur in the margins near the edges ... the lack of significant scarring
The number of folios in the Codex Sinaiticus with maker’s holes is small and when evident, the holes tend to be located in the margins, well away from the text. The majority of the holes themselves are small (<5mm in diameter) ... no obvious evidence of a makers repair apart from a part-obscured hole... Evidence of striation on the folios of the codex is not abundant
And very unspecific notations:
- Affected by long-term ink corrosion.
- Affected by gelatinisation
All analysis and description is circular, assuming the age from the textual critics who got it from the Tischendorf con, and then the British Museum were the Russian marks.
=================
"The method of pricking and ruling
[21] set the model for later Greek and Latin manuscripts that followed in the next 1000 years."
This looks like an acknowledgment that this is actually a later development than fourth century.
Similarly:
"the margin areas are generous at a time when parchment was expensive to produce"
=================
"the twentieth-century binding tending to hide its codicological history"
An allusion to the disaster of the Douglas Cockerell binding mania, which was pointed out by Kirsopp Lake.
=================
Actually helpful microscopic analysis:
René Larsen
[27] has determined two types of animal origin; calf and wool sheep (see figs.3 and 4). He examined 28 folios with significant follicle evidence and was able to positively identify 15 as calf; 4 as most likely calf; 2 as wool sheep and the remaining 7 as unidentifiable.
