דיוחנן - kosher rapidograph ink.... Experiences or comments pls
I recently tried this kosher ink for my rapidograph and I am extremely pleased with it. It does not clog the nib like other kosher rapidograph inks, and it's very dark and strong. It's at least as good as the Rotring commercial grade rapidograph inks (of course these can only be used with batch numbers that have been lab tested and approved kosher), and in addition you do not need to add a drop of regular Sta"m ink (as per the instruction of the Shevet Halevi, which is messy and time consuming). I was wondering if anyone else had an opinion or comments with regards to their experience with this ink...
put a matlis on from behind with PVA glue
ReplyDeleteElmer wood glue is very strong and good for a Matlit. Some time ago I talked to a chemist at the company and he assured me that all ingredients are synthetic, no animal ingredients.
ReplyDeleteThere are two different materials called PVA.
ReplyDelete1) polyvinyl acetate
2) polyvinyl alcohol
The first one is a good adhesive and is used in Elmer (and others) wood glue.
The second one is highly water sensitive and quickly deteriorates in humidity.
Use only the first one. Never use the second one.
Instead of a matlit of k'laf you could also use Goldbeater's skin that has been prepared lishmah - I recently got a local Rabbi/shochet to make this for me and it is excellent for rips as it is very thin but very tough.
