2014年2月25日 · The very top of this particular thermometer had a small bulge inside, so as the alcohol reached the top it spread out and the split bubbled itself away. This will only work if the thermometer's maximum temperature is below the boiling point of water. Be careful not to overheat it, or you. Disclaimer: This worked for me. Once.

2023年12月4日 · Actually, it used to happen with mercury thermometers, too, but these were even easier to 'fix' by just forcefully whipping the thermometer a couple of times so that centrifugal forces push the liquid back towards the end. This works with alcohol thermometers as well, but a little less so than with the old mercury ones.

2015年6月19日 · I use my Kodak Process Type 3 mercury thermometer as my darkroom standard. I calibrate my Kodak Deluxe alcohol thermometer against the Type 3. That calibration shows that the Deluxe reads exactly 0.5F too high at 68F. However, I don't have a calibration constant for the Type 3 itself. I simply define it to be correct for my purposes.

2014年2月25日 · It was a $4 thermometer, but still. Interesting that it is alcohol in there, not mercury. In school science class we used to play w/ a blob of mercury, letting it roll around in out hands. I'm still alive. Like Roger said, I only use my dial thermometer for mixing up D76 at around 130 degrees, where I have a 10 degree flexibility.

2021年2月26日 · I wonder if the haze is an impurity that doesn't evaporate fully, or if the alcohol actually alters the emulsion, maybe slightly dissolving, which could look hazy when dry. Here in Australia, the main brand of solvents available in the local hardware shops has a reputation among some fussy users that it leaves a residue after evaporating.

2020年11月29日 · You may be able to buy alcohol stove fuel from a camping supply store. I don't live in California so I can't check, but my understanding is that the vast majority of denatured alcohol was used as a solvent, not for fuel, and CA, Canada, etc banned it to reduce VOC emissions (ie the tiny-by-comparison market for alcohol fuel is not what they were concerned …

2025年1月5日 · hi all, I'm new to color ra4 processing. I have done a couple prints in my cp51 fujimoto and the results were ok. I tried first some expired paper then I tired some dpII paper because I heard it's the best at the moment in terms of …

2016年6月12日 · Therefore ethyl alcohol remains in their bodies longer. A friend in college was half Native American. Two beers and he was gone for the evening. The federal government lists hundreds of approved denaturants depending on the final use of the ethyl alcohol. Little concern is expressed for the unfortunant who consumes the alcohol.

2020年7月15日 · Alcohol - the cure and source of all problems! I have two Canon New F-1 cameras. One is the coveted 1984 edition, which works just fine, the other is a very battered camera, with a very dented AE prism.

2025年1月30日 · That said, any mixture of an acid with some alcohol could work. Acetic acid with isopropanol is one I have heard of, but never tried myself. Kodak suggested formulas like TC-1, which is sulfuric acid, potassium dichromate and water. These ngrediends are hard to come by.
