soak wood in water and wood spoil
I've soaked two boeard of mullberry in water.at the second day some black dot apears on both of them exactly under the stone which i've put on it.i've used alcohol as antidetergent but because of summer here it eveporate soon.is the wood going to spoil?and can i use hydrochlorid acid or bleach?
Happened to me with maple.
I guess the place it was drying out was not ventilated enough. Wouldnt reccommend direct sun exposure, but a dry place with natural circulation of air would do next time.
Wood is rottenning by the way. Try to clean it with sand paper. See if it persist.

If you are going to use it for bows, it will need to come into contact with glue. You should avoid using strong chemicals. Only some alkaline solution could be used for removing grease.
I do not understand why you are soaking it. It will have to be well-dried before you do any gluing.

Still bowyers are soaking wood for bending. That?s a uselless procedure.
Bend your wood when it is still green by clamping it to the desired shape, if the wood is dry steam- bend it. I f you want a small bending dry- heat the belly-side of the wood.
For the dramatic curves of a Scythian bow or for siyahs look for grown pieces of wood.
The black dot is caused by some ferrous minerals in the stone reacting with the tannic acid of the wood. It?s nothing else than a colour, no rotteining.
It happens too, while steambending wood using metal clamps for forcing the wood to a desired shape.
As Stephen has mentioned avoid strong chemicals for some cleaning or degreasing, otherwise the glueing with natural glue will not work.

Soaking and boiling is well working method for wood bending. It is possible to bend thick pieces to big angles.
Clamping while green will result to bend, but it will go away when bent back.
(This may or may not be a bad thing in composite bow core, but for sure it makes reflex/recurve from selfbow to disappear.)
NOTE: Clamping while green is working way to remove twists etc, where the bow is does not bend against the force.
Hot air gun can be used to bend dry wood, but not thick pieces to big angles.
Some people reportedly have used steaming with good results, I have not been succesfull.

I use saoking for bending on forms.Thanks for your answers.
Black dots can be a kind of fungus too. In high temperatures and high humidity this can be a real problem. I have had it happen with thick bamboo that wasn't cured correctly. Sydney has high summer temperatures and high humidity. Soaking the wood replicates the humidity problem. I assume summer in Tehran is hot too.
I think you guys who have not been successful with heat bending wood should not declare it a pointless technique when masters all around the world rely on it for excellent bow making.
Possibly you should inquire as to the successful technique.

Yes Bede here is too hot this summer and the black dots doesn't growth any more!
Jack i've seen people doing it very nice but i thought this may be easy for me and i'll try thhem too.

Jack has a point. As I wrote a long time ago, there are a lot of bent wood walking sticks around and they were all heat bent. I have my grandmother's somewhere in the house and it hasn't straightened a bit in 60 years.
I am glad the black spots aren't spreading!

heat bending is kind of magic but
its much more fun to hunt for naturally grown siyahs, not ?
and success is guaranteed - no chance for splinters :roll: or breaks :shock:

At last i've done it.after a week soaking in water and 90 minutes boiling in water the wood(mullberry) was like butter.
it's dimension is: 24in.4.5cm.10mm :D
you can see the black dots and grain in pics.
