Silver Thickness , Rubylith Film , Gas Mask Filters, Mercury Heating

[bunyaminergen]

Hi,
I have a few questions.
– Is it enough for the three to four microns in thickness of silver?
– Can be used Rubylith instead Ulano CDF for the Becquerel Process ? *
– Which filters should I buy for the gas mask ? ( Mercury , Bromine , Iodine )
– What do I use to heat the mercury in mercury box ?

Hi,

I think 3-4micron won’t be enough. I read it somewhere you will need at least 6 microns. I’m using 10microns silver thickness.

I have never heard about this Ulano CDF film. I bought my red film in a simple paper store. I have to use it in 6 layers to minimize blue tones to 0 and get black and white. Need to filter out other wavelengths. 1 or 2 from Rubylith film is usually not enough, plus you will need enough power and time, maybe 1000w lamp for 2-3 hours. Blue tones means underdeveloped Becquerel plate!

I’m using 2 3M gas mask. One with 3M 6057 filter for bromide, iodide and the other is for mercury: 3M 6096 HgP3

Others can help you how to hear mercury.Maybe alcohol lamp will be fine. I’m using vacuum development, so I don’t need to heat.

Thank you so much,Bakody. I’d like to try that method of development. For this, I would like to receive information from you later. First of all I need access to the method of Becquerel and mercury vapor. 🙂
Which source have read six microns information?
Would be enough normal red film, in order to get the image? I think I will use the first time around the sun instead of light.

I could read about 6microns somewhere here in the forum. But that one is the minimum I think. At the beginning I think you should use more, 10microns and you can repolish your plate 3-5 times.
Yes, just a simple red (red, dark red) film is enough for Becquerel. Order more to able to use them in more layers. Sun light will be ok at the beginning.
Ask if you have any other question!
Good luck!

Thank you.
But,you do you mean here?
”you can re polish your plate 3-5 times. ”
If it fails, the process can we get to deal with again, did you mean?
So,polish again than bromine and iodine … If the image does not occur.

Yes, at the end if you don’t like the final image, you can reuse your plate. How many times you can reuse it it’s depend on your polishing technique.

Thank you so much Bakody. 🙂 This information is very important to me.

[Bakody]

Maybe at the beginning you should use 10-15 micron silver thickness and you can reuse them.

Yes, you’re right. I’ll wrap the other plate 10 microns.
