I am rather curious to try it out withcement. Somebody somewhere told me that it blackens instantly or very quickly when that method is used, but that can't be true can it? I suppose it just darkens as the normal ammonia dipped henna does? ~Nick : I think you emailed me .... : Here's the answer in case someone else need to see it: : : The technique is very simple and widely used across North Africa and : the : Middle East. It's not confined to Egypt at all. : : Apply your henna. Let it dry and seal it. Leave it on overnight if : possible. Scrape it off. Make a paste of high-lime cement or slaked : lime. (that does the job and is less vicious on the skin than : quicklime!) Slather that on the hennaed part. Heat that and keep it : on as long as you can manage. Scrape that off. : : Quicklime is used to quickly decompose corpses and road kill .... so : DO be very cautious about that! Calcium hydroxide and ammonium : hydroxide have very similar effects on skin ..... and the alternate : technique is to use some form of ammonia. ....stale camel urine, stale : bat urine .... or very, very cautiously, household ammonia. These are : all NASTY on the skin! : : : What you're doing is zapping the H off the hennotannic acid molecule : by hitting it with a base that swipes H's. : : Details are at the links below: : : : There are other ways of blackening henna ...... go through : http://reverndbunny.sphosting.com/ammoniatrick.htm : http://reverndbunny.sphosting.com/howmix.htm and the whole of : http://reverndbunny.sphosting.com/reverndbunny_sphosting_com.html ... : so you can see how repeated steaming and heating, or addition of : terpines will do the job.
