Confusion over Blythe’s C1 and C10 enamels.
Earlier this year someone noticed that the Milton Bridge website (263 series) and the Vitrum Signum website had different descriptions of Blythe fluxes, so Milton Bridge asked Vitrum Signum to correct theirs. C1 and C10 fluxes have not changed (nor has C2).
C1 has always been called gold flux and C10 medium flux on Milton Bridge website. (263 series). Vitrum Signum got the description wrong years ago. (I looked at the Jeanne Werge-Hartley book on Enamelling on Precious Metals which gives a list of some of the enamels from Vitrum Signum and the description is wrong there too.)
