    Thanks Sandy and PE. It seems clear the rod and sign material is easier for carbon. Maybe the coating blade would work well for albumen since you can adjust the thickness of the coating with the blade instead of using the double floating method.

    I'd just like to add that the victims, err subjects, of the Florida kleptocracy can not buy or possess ethyl alcohol above 153 proof under penalty of felony charges. Everclear 151 proof ( 75.5 % ethyl alcohol ) and the identical Graves Grain Alcohol 151 proof are available in South Florida, and legal to own.

    We have the same problem here, but we are at least allowed to possess it here in NYS.

    DO NOT UNDER ANY CIRCUMSTANCES USE DENATURED ALCOHOL....

    This warning holds especially if the denatured alcohol becomes cloudy when poured into water.

    I was given this warning at EK, and so I have never tried to test it, deeming my hand and machine coatings too valuable to mess around with. Besides, we were not permitted to have denatured ethanol in the labs. We used 95% or Absolute (99.99%) ethanol.

    Would the drugstore stocked isopropyl or methanol available in 90%+ be usable for thinning ?

    Methanol can be used as can isoporopyl (IPA), but the IPA is a bit more oily and evaporates more slowly.

    Denaturants added to either of these products, that cause cloudiness in water are reportedly harmful photographically though so take care and test first. Methanol fumes are very toxic. Used in large quantities it can be harmful, and can be absorbed through the skin. IPA can cause some respiratory distress as well.

    Back in the early 80's when we used to make punch out of it it was purchased in Connecticut

    Everclear is 95% ethyl alcohol. It can be purchased in many states at liquor stores or drug stores. In some states (Dry States) it is banned. There is also a version that is even more concentrated sold under the same name, and there is Absolute Alcohol which is about 100% pure. Absolute is sold mostly by chemical companies.

    Don't drink any of them. They are prepared from a benzene water mix with the alcohol and the mixture is "azeotroped" to get the pure alcohol, but there is some contamination by benzene.

    Azeotrope = http://en.wikipedia.org/wiki/Azeotrope see: Separation of azeotrope constituents
