Well, it seems like a bit of time has elapsed since this particular topic has been visited or discussed....
Interesting past history here...
Well, let me get to the point.... or maybe after a few sentences here...
First of all, can all of you tell by my slightly increased input here that winter is fast approaching the northern lands of the USA? (God help you all...!) 😉 I feel cabin fever even before Thanksgiving and Christmas!
Secondly, is anyone else on these threads having at teast some slight difficulty in finding a particular and specific topic which they want to revisit? I just spent quite a few minutes doing a search on various main thread catagories, using merely the words "humidity" and "relative humidity", and came up with zilch!. Then finally, using the words "ivory" and "humidity", I somehow arrived at this thread. Thank goodness! I thought I was going to be searching until Spring when the Siberian thaw occurs in this region of the USA...!
Well, I digress once again.... so, what's new?
Well, I'd like to call all climatologists, scientists, biologists, meteorologists, chemists, etc. - out there, in the cold cruel world - to enter this discussion once again.
Heck, even the folks in that other smaller and selective group might want to join in this tiny discussion right here.... You know... you guys who (I think) are among the "upper crust" of chess collectors.... the ones with the dough and bread.... (Gotta love the puns it, right?) Hey.... I am just feelin' a little more cheeky than usually on this brisk Saturday Morning...
So, what I would like to know what the difference is between "humidity" and "relative humidity". (yeah, I know... I know.... "...it's all relative..."... and it has something to do with the temperature, relatively speaking...)
But I'd really like to get the info from the horse's mouth, sortaspeak... It tends to be all "Greek to me". I think I could understand if someone were able to say it in simple American English... sortaspeak...
I have two hygrometers (digitial humidity gauges, which also show temperature.) Placing them side by side, they are within about 1 % humdity of each others. That holds true for the temperature too.
I now have - not only some ivory chess sets to worry about - but also - as some of you know - a baby grand piano to fret over....
I hear that the humidity (relative humidity.... "R.H." should be between 40-60 %, inclduing winter.... but that in winter, to expect a more reasonably hoped-for % of about 30 - 50 %. I may need to use a humidifier, but I will be careful about that because i do not want to create an adverse situation with too muich huimidity and mildew, mold growth, etc...
Ok.... your turn...!
Thanks!

noybear, I am very interested in your idea of using the diecast car display cases. Which scale size cases do you use?
sorry John, I know nothing about humidity except that we have relatively low humidity out here. It's also going to about 7 degrees cooler today than the average temperature for this time of the year. The high today is 'only' going to be about 50 degrees. neider neider neider
I am willing, however, out of the goodness of my heart, to have you send me your chess sets to keep preserved for you with our kind temperatures and humidity. (I wouldn't do this for just any chess collector, you know. Well - maybe I would.)

Baron,
I use 3 different sizes that this company has available, for 1/24th and 1/18th scales.
The product numbers are: 094C, 355C and 576C by Pioneer Plastics. http://www.pioneerplastics.com/display-cases/
Unfortunately, I am inept at uploading to Picasa and other sites but I would be happy to send pictures to a direct email to anyone that asks. My one wall currently holds 97 sets with space for 5 additional small, 1 medium and 1 large case to approximately level off all columns. This is on a single 10 foot long wall. The supporting shelf sits 18 inches off the floor, protrudes out a mere 8 inches and the top of the tallest column is 80 inches off the floor. I did not go to the floor because of unevenness of the carpeting and trying to bend down or get on all fours to view what is so low nor did I go any higher because all I could see would be base felts unless I looked from several yards away.
I also am unorthodox in that I use Scotch double stick tape in strips on the base of each unit and place the pieces on to this. It provides just enough holding power to keep pieces in place during moving them into place but also is enough so that I can unstack to retrieve a particular set and place everyone back or rearrange what is in which column with next to no effort.
A friend calculated that for the 242 sets in cases, I spent something less than $1,500 and I defy anyone to display more for less out of dust and so forth. I chose these after looking into several others that are available on the market because of the stacking ability and they are very solid placed into such columns. The additional beauty of my doing sets in this way is the small "footprint" of lost floor space in any room compared to even bookcases and of course curio cabinets are even worse.
To fairly represent this idea, I do have a few that the cases cannot be used with such as the FM Chess Set of the Gods (1/4" too tall) or my Nigri "Louis XIVth" because of the base widths so I do have a cabinet for my few "oversize" sets but there are only 9 of these to date.
The last advantage to this system is that each set of pieces is as dustproof as humanly possible in that the top for each is a friction fit that fingernails (I don't have any) or a letter opener or similar is needed to get them to release from each base.
I will be glad to send pictures directly to anyone that requests them, as I said. If I can be of any further help, you can post within the group or write me directly at: noybear@hotmail.com

Thanks for the info, noybear. I also collect diecast cars so am somewhat familiar with the plastic cases but have never thought of using them for chess sets. I would love to see some pictures to see how they worked out. My email address is duncanpohl@sbcglobal.net. Thanks.

Ok, all.
Let me try to - at least for now, get back to my question I made on November 19th. (Persistent little bugger, I am, eh?) And let me try to be a tad shorter and more direct. So, here, I narrow down my discussion...
So, what I would like to know what the difference is between "humidity" and "relative humidity". (yeah, I know... I know.... "...it's all relative..."... and it has something to do with the temperature, relatively speaking...)
I have two hygrometers (digital humidity gauges, which also show temperature.) Placing them side by side, they are within about 1 % humidity of each others. That holds true for the temperature too.
I now have - not only some ivory chess sets to worry about - but also - as some of you know - a baby grand piano to fret over....
I hear that the humidity (relative humidity.... "R.H." should be between 40-60 %, including winter.... but that in winter, to expect a more reasonably hoped-for % of about 30 - 50 %. I may need to use a humidifier, but I will be careful about that because I do not want to create an adverse situation with too much humidity and mildew, mold growth, etc...
Basically, what I am wondering about is: A.) is a device, which gives/shows digital "Humidity" reading/number, actually mean "Relative Humidity"? If so, then fine. I would be aiming for about 50% for my ivory sets as well as my piano. If not, then what do I do to determine what it means? (How should I assess the number?)
Ok.... your turn...!

Actually, John, I wish I knew the answer to your question, it's a good one. But someone should know, then we'll both/all know the answer.

"Relative humidity is a term used to describe the amount of water vapor in a mixture of air and water vapor. It is defined as the partial pressure of water vapor in the air-water mixture, given as a percentage of the saturated vapor pressure under those conditions. The relative humidity of air thus changes not only with respect to the absolute humidity (moisture content) but also temperature and pressure, upon which the saturated vapor pressure depends. Relative humidity is often used instead of absolute humidity in situations where the rate of water evaporation is important, as it takes into account the variation in saturated vapor pressure." - from Wikipedia

It's worth reading the whole article - especially the section: "Misconception"

Keith,
Before I "hit the sack this evening", I feel I owe you a thank you for the link, etc. Today, (after a few hours of work), I stopped by a Steinway Piano Dealership and spoke with the owner who has been doing piano sales, tuning, and repairs for 40 years or so. He said that most people (and manufactures of hygrometers) use both terms (humidity and relative humidity) interchangeably.
And he said that (at least for pianos), to try to keep the % between 40-60%... the closer to 50%, the better. I have also bought an ultrasonic humidifier, in case I see the moisture level goes below 40 %.
It is interesting that a small hygrometer, which I just brought from him today, does not even have or use the word "humidity" in it's self-identity. It calls itself a "moisture monitor"!
Thanks again for your input and attempt to help.
I would think that all of this might be good info for ivory chess sets too..... speaking of which... I like my ivory chess sets as well as my plastic sets. I love 'em all...!
John.

I've been redoing my setup a bit lately and have found the 1/18 scale di-cast car cases quite handy for my of my sets... some sets are a little too tall. I'm still shuffling things around, but can probably take a few pictures of my setup with the new cases today, though only for this group esp. as I probably won't be able to take them without also taking pictures of my reflection taking the picture in the mirror back. I'm still keeping my favorite sets in the big cabinet, but the di-cast cases are certainly a more efficient use of space, fit all chess sets but the very largest, and might be the best way to go for someone with a lot of sets to display in a limited space.
