Electro etching question

[andy gascoigne]

I have just made myself an electro etcher and have managed to make my own stencils. Can anyone tell me If I can re-use the developing solution for more than one stencil or do I have to throw it out. I know this sounds as though I'm being tight with the materials but as I live in the U.K and can only get developer from the U.S I have to save some costs.

As far I know you can re-use it many times. There should be some info. that came with it on when it is depleted. My system's instructions say when the solution turns yellow to replace it.

Thanks for that, I got the developer and stencils from Martronics and they did'nt send any information or instructions

Thanks

Andy.

I use the EDX-40 developer from IMG and have re-used it many times. I would imagine your developer would do the same. It might be wise to store the used developer in a light tight bottle. I'm not sure but strong light might help to break it down....
