Very good advice and information. Thanks for sharing Sam.
Take care, Dave
Thanks Sam, I live in Saskatchewan Canada. Moisture is high here. The knowledge you shared will help a lot!
Yes indeed Sam, very help information. Thank you for sharing. Ohio
Some very important issues addressed Sam, thank you.
Cheers

A very good vedio with excellent advice. While not ALL mold is harmful I like to think ANY mold of any species in the lungs is bad news. Better safe than sorry. Thanks for another excellend video Sam.
Regards
Brian
Thanks Sam. Mold has been a big concern. We all love spalted pieces, but no one should be breathing the dust while turning. Good points with the bleach. Will try it.
Very good video! When you figure that different parts of plants and trees have had chemicals, drugs, and poisons extracted form their roots, barks, flowers/fruit, (and molds)., a respirator starts to make good sense.
Thanks for the infos Sam.
thanks for all your great advice
Thanks for watching Sam
Good information to be aware of. But as you say, mold is everywhere. so we should not be paranoid about it. But deal with it appropriately when it is apparent.
Also to leverage it for color and other changes to the wood when possible,
Thanks
Alan
Yes, too many things to think about. But I wear my dust helmet most of the time. Thanks Sam
I was having some strange medal conditions a few years back. Rash, burning eyes, and the worst was a condition called Lichen Planus. Most people get it on their skin a few people get it in their mouth. I got it in my mouth. It was horrible. Pain, burning, could not eat. Seemed like air hurt it. No joke. It took 3 doctors 2 dentist then finally a Pathologist diagnosed it. The doctors thought it was thrush. Anyway found some mold in my damp basement. Treated the mold and everything cleared up. Horrible experience. Thanks Sam!
As I grew up in Ohio we dealt with a moldy basement all the time...nasty.
I hope you are over you malady. Sounds awful. Sam
Strange that with the humidity here in Georgia, I don't seem to get that much mold on my rough turned pieces, although it does happen occasionally. I share your concerns about breathing in mold. Thanks for sharing.
Hey Mike....
Just saw this. I wonder if the specie of wood has a lot to do with it. I turn a lot of box elder and it seems to always get mold on it. Sam
I suspect it does. I rarely turn box elder. I turn a lot of Bradford pear and rarely get any mold on it.
I live in Wales, Uk and we are not known for a dry climate. If I leave bread out in the kitchen, I can guarantee it will be mouldy in a couple of days, so presumably the spores are in the air all the time so my lungs must be full of them. Probably some spores are dangerous and some are not.
Thanks for the video highlighting a possible issue.

Thank you for this video. The first thing I have to say is that I live in Ireland which has a very wet climate simply because 90% of our weather comes charging in from the Atlantic. It's therefore very moisture-charged and the clouds dump it over us in the form of rain and more rain.
I've turned several items of spalted wood and the patterns are just amazing. Several people have asked me how do I get wood to spalt. It's not very scientific and I tell them I just throw a log under a hedge for a few months. The mould soon takes over but the secret is to stop it by drying out the wood at the right time and therefore killing the mould.
The results can be spectacular and as evidence of this a few people have asked me had I hand-painted the pattern.
I wish I were so talented.
Alan, yes. stopping the rot in the wood at the correct time must be a challenge. We don't get much spalting in Wyoming. Sam
WOW,, thanks for sharing,,very informative
Great video Sam! I would have leaned toward the vinegar because I have seen it work well and I am not as woried about the fumes. Did you have two knee replacements? I see some serious scars and know about knee issues myself. Two meniscus bucket handle tears and surgery on both 18 years apart. Not fun. Really enjoy your videos and always learn... Thank you and keep on making great videos!
Yep, the knees were 2 of the 12 major surgeries. I don't count the little ones--I can hardly remember all of them haha. I suppose getting my fingers sewed back up counts in there. Oh well. Sam
I have have just picked up some small logs that I treated with end sealant and kept in a black plastic bag from May 2018 till now 2019. I sure slowed down the drying since they are still at 22% and nearly perfect for turning mushrooms, except that some of them have mold. If I store the logs in my workshop for a few weeks and then turn them, is it possible that the mold could spread to the fabric / structure of my Garage. I too live in the very dry state of Montana. Thanks, Jim ....Montana Wood Art.
excellent info. I have some mould on a piece spalted Alder. this happened because I let the roughed out bowl that I carved dry to much n it became hard to work so I soaked it to put the moisture back into it, then I put it in some shavings over night because it got too wet, well the next day I went back to it n it was covered in mould spots. I think I'm going to put this out to the sun with vinegar n water as this is safe n has untold uses. bleach can be as bad as the mould itself. Thanks.
Good Job on explaining.Since lack of light is a condition maybe storing in garbage cans might not be the best also lack of air circulation does not help maybe try a Bakers rack ( wire form shelf unit)and cover with clear poly sheet and do not completely seal Having visible might allow for better control.
It is so dry here I might have other issues. I usually end up with my pieces in large paper lawn bags which might let more air in. I usually don't have a problem this severe as shown in the video.
Sam
Good video
Sam, I would suggest that you revisit the advise to use a chemical respirator. Chemical respirators do not *necessarily* filter particulates. Many of them are "combination" chemical/particulate respirators, but even then they are usually N95/P95 - or worse. I wouldn't personally use less than a P100 rated particulate respirator. Clyde (old guy with asthma...)
Yes I too only use the P100. A fine point worth knowing. Thanks Sam
Great subject. I never did trust seeing mold on my pieces.
I live in northern Nevada and we have mold here too. Even when the humidity is less than 10%. My problem is the mold looks like a black or gray stain that travels in the grain and not in spots. I'm planning on trying the bleach mixture to see if I can get rid of the stains. Anybody else have this problem, and what did you do the correct it? By the way, the wood I'm using is Pine and Elm...same problem on both.
I can always get mold if I put the blanks in a garbage bag for a day or two. I do this to stop any drying till I can store the blanks properly. Sam
I have a wooden bowl that is about a hundred years old . It has what looks like pine straw woven into the rim . All of a sudden I noticed it is covered in mold . I don't want to damage the patina . Any suggestions .
You might try setting in the sunlight for a while each day. This may dry out the mold and kill it. Other than that all I can think of is a very ,mild bleach and water solution. You might try a small test area and see what happens. but the bleach may cause the color to fade. I am just not sure. Sam
Mold is unusual structure of the tree. If you have the opportunity to fix it and give strength, it will be beautiful. Like!
My understanding, which could be wrong, is that spalting which is caused by fungi and makes the beautiful designs, is different from mold. My experience with mold is that it tends to stain the wood a kind of muddy grey which is rarely attractive.
I say, if it were possible to convey the richness of the fungus in the wood.
I hope all take this advice,Very important. I'm tired of watching wood turners coughing as they inform us of safety procedures sans mask!!! I'm in florida, with high temps and humidity. Bleach is my cheap allie!!! Works!!! Thanks...
Well, made it as far as Gray Bull last week. Maybe next year Sam.
Yes, just 35 miles north here.
Sam
Unless you plan on shaving your beard, that's not the correct respirator. You need a powered air-purifying respirator with a hood or something that doesn't require a good face seal. Nice video.
Just want to point out, not all your followers are in the US! I'm in Britain here for example.
Yes I know. Did I say something in the video? If I did, I did not mean to offend the rest of the world. I will go back and look. Sam
Yes, I did say America.....I put up a note in the video. I do thank you. I will be more sensitive to our total community of World-wide turners. Sam
Yes, put up trigger warnings in the future! Seriously though, I was just mentioning your viewers are from a far wider area than you may have realized ;^>
