<p>[QUOTE="808 raver, post: 12490756, member: 4654"]TBH I couldn't say exactly the timing but the moist environment softerns the internal collagen of the ivory and the clamping should reset the twist. I would clean the frame before you start because you don't want rust or any other things to leach into the ivory BTW remove the screws and stand, then I would try 5-7 days in a tupperware box, with the sponge in a separate open container also inside the box, when you clamp it put a matchstick under the corner that's low because you still might get some springback, I would leave it for a few weeks clamped, 2 maybe? and check on it then, all of this depends on thickness, temp, how much moisture it took on ect, don't use heat though. You might have to repeat this process and you will have to workout what part failed, not long enough taking on moisture or didn't leave it long enough in the clamp to dry ect.[/QUOTE]</p><p><br /></p>
