Re: glute?

Hi Jack,
Mine says on it LPP 92/LPE520 and on the back, all in German, it says all
this stuff but a formula of developer concentrate (125ml) to 775 ml water to
100ml of Black Magic and fill with water to a liter. It also says, "This
sequence is strictly prescribed". I am assuming it is 2.5%, but in the
sheet inside of the box it is unclear to me as it is in German, and it looks
like it says 20-25%. I emailed Maco and they did not email back. But the
Maco MSDS says it is 2-5%. So I don't have it figured out yet whether the
box insert is just written weird or they changed the formula or there are
two separate products. I wish someone who spoke German on the list could
tell us.

All I know is when working with 2.5%, 6ml, to the liter of 3% gelatin, it
stays liquid just fine although it feels smoothly acrylicish once dry, if
that can be a correct descriptive term. I left some of the hardened stuff
outside and it didn't turn to rock. Keith Gerling, if I am not mistaken,
added too much and he got instant rockness. But I don't know what brand or
proportion he was using.
