Fresnel lens

[21st century pict]

I was reading through some of the early posts on posable fire lighting techniques on the BG Island show,
one member mentiond using a pair of reading glasses , it was a nice sunny day so I gave it a go on some char cloth , the spot wasn't to great but I got the cloth going easily enough, another member mentiond adding a drop of water to the lens to improve the spot but unless the sun is directly overhead the water just runs off the lens , so in a effort to improve my technique I have orderd a 3x2 Fresnel lens x4 I'm still wating for the lens to arrive and was wondering if its posable or if anyone has tryed lighting a wet fire cube? I have a Horses hoof fungus in the garden , anyone tryed Amado?
Cheers.

I've lit fatwood very easily with a small one, and birch bark; if you hold it by the ends between fingertips and bend it slightly you can focus the hot-spot quite precisely.

That's just reminded me that I have a US army one the a military friend gave me, must give it a try this summer if we get enough sunshine!

I got a pack of these very cheaply on ebay. Credit card sized that fits into my purse very tidily. Pennies really

They do work, on vaseline and cotton wool, on the birchbark and on the brown, not bowed fast enough, dust from the firebowing and on chaga and King Alfred's cakes.

Like these ones at 40p each.

I once set my bed on fire with a fresnel lense. The fireservice didn't believe me...

I've used amadou, chaga, cramp ball and char cloth with the one on my Hudson's bay tinderbox, it works well, can be tricky to focus at times but on a Nice sunny day it works well, but I much prefer the flint and steel myself.
