Why is Noodler's Baystate Blue advertised as being alkaline? The bottle says ph between 8-9, and various retailers advertise it as being slightly more dangerous to pens due to being basic. Yet, many sites including richardspens.com and a thread here quote the pH as acidic, in the 4-5 range, and when I pH tested my bottle in lab today with a ph probe I got a pH of 2.96, which is 1,088,484 times more acidic than the quoted pH. (pH is measured on a logarithmic scale with a pH value representing a Hydronium Ion Concentration of 10^-pH molar, so pH 5 is 10 times more acidic than ph 6, which is 10 times more acidic than pH 7, and so on). Could Nathan have meant to list 8-9 as the pOH? I can't really think of any other explanation. Edited to say: Even if he did mean pOH, that would only mean a pH range for the ink of 5-6. Measured values have been significantly more acidic than that, by a factor of up to a thousand.

Just seen on Purepens that they now have a wider range of noodlers, including the infamous Bsb, at £12.50. Good deal ? I may have posted this in the wrong place, feel free to move it ! Just a heads up for any UK lovers of Noodlers....
