Chalk surfaced paper.

I wonder if anyone has any means of simply identifying chalk surfaced paper on stamps without damaging stamps.
What method do you use that is failsafe ?

This can make a huge difference in completing a set, and also the value of the stamps.
Do you not bother with it because you do not know how to identify chalky paper ?
I have been stamp collecting for a long time, and have not yet come across a reliable way of identifying chalky paper.

I am currently concentrating on my Edward 7th GB stamps, which include many chalkies. I am looking for a quick and easy way of i.d'ing them.

Have been collecting for 54 years now, consider myself a collector not a philatelist as my equipment consist of black plastic tray for watermarks, tweezers, hinges, mounts and home made pages. I really have no interest in value at all, it is the seeking out I enjoy, I know I have no chance of ever getting a full collection but who cares. Years ago I read up on ways to identify chalky paper but none were reliable as far as I could tell so decided to not bother, can't even remember what they were now.

Silver leaves marks on chalked paper. It is not quite "undamaging", but fairly reliable. Don't press too much - light marks can often be wiped off.

Other than that, chalked paper usually has a very smooth surface (which is the purpose of chalking after all). For comparison purposes, the Austrian definitve issue of 1908 may be used. 1908 printings are on chalked paper, 1913 printings on ordinary paper.

Chalky paper is a philatelic term for a type of paper coated with a chalky solution for security purposes. The postmark cannot be removed without damaging the surface of the stamp thus discouraging erasure of cancellations and fraudulent reuse of stamps.

Myles Glazer published articles which state that the silver test reaction is nothing whatsoever to do with chalk in the surfacing of the paper. John Hereford published a response to this in Geosix, FM Whatsapp Downloadholding that the mark left by the silver test is actually caused by tarnish and that the chalk which is reacting with the tarnish is in the form of chalk powder residue on the surface of the stamp, rather than chalk present in the coating. These excellent contributions to the debate approach the problem from a scientific viewpoint; we need to consider where this leaves the collector, dealer and catalogue-editor!

If you tilt the stamp at a very steep angle to a light source, chalk surfaced papers often appear shiny compared with the non chalky papers. Master Royale Infinity Download
I am not sure if this works in all cases, but the the British issues ( Victoria, Edward VII, George V) in the early 20th century this works well. mod apk download

I completely agree with you.
