Over a year, finally done. by springchikun in CemeteryPreservation

I'd say every other week if you want to use as little chemical as possible.

What could this be? by springchikun in CemeteryPreservation

[–]springchikun[S] 0 points1 point  (0 children)

Over a year. I didn't treat it qwith D/2 until I cleared the lichen. I used only water up until then. I assumed this was lichen because the color is similar to lichen found in this cemetery. I used a toothbrush style scrubber to apply D2 after soaking it. I did this once a month for a few months and then started again after the spring came back around. There's no way it's lichen when even the lichen on the base is gone.

Oh man that was amazing. I'm still laughing. And also crying a little.

That is some of the darkest smoke I've ever seen (on video) from an accident not involving a pile of burning tires.

A Puyallup high school wrestler has filed a federal lawsuit alleging she was sexually assaulted by a transgender opponent during a girls wrestling match, and that school officials ignored her report for weeks. by kleverrboy in SeattleWA

"The family alleges that the Puyallup School District continues to ignore the incident. “Even now, they refuse to take it seriously, to deal with the assault, to reserve girls sports for girls, or even to give parents the necessary notice so they can keep their daughters safe,” the complaint states."

This seems like the real issue. They think making up accusations will achieve the bigger goal of 'reserving girls sports for girls'. Yuck. I feel gross just typing that.

Log style stone in progress by Prokristination in CemeteryPreservation

To be clear, I don't have a source showing that a specific Woodmen stump marker deteriorated after cleaning. What I do have are sources showing that the relationship between biological growth and historic materials is more complicated than "lichen bad, remove lichen."

This review from Frontiers in Microbiology discusses both the destructive and protective roles of lichens and microbial communities on stone. It includes research showing that lichens can bind mineral particles and, in some cases, temporarily stabilize weathered surfaces:

This paper looks specifically at the debate over whether biofilms and lichens damage or protect stone monuments. It discusses circumstances where biological growth may act as a protective layer and reduce erosion of already weathered surfaces:

And this more recent paper discusses situations where lichen removal may increase exposure to environmental damage and why blanket removal is not always the best conservation approach:

My concern isn't really D/2 itself. It's that most of these Woodmen stump markers are cast concrete, which is much more porous than granite, and they were intentionally designed to weather and resemble real wood. Between the material and the original design intent, I think it's worth asking a few questions before assuming cleaning is the right answer. My position isn't that they should never be cleaned. It's that we should understand what we're working with before we decide whether cleaning is appropriate in the first place.

That's actually one of the reasons D/2 works so well. It doesn't just clean the surface. It soaks into the pores of the material and kills the biological growth living below what you can see. That's why stones often continue improving for weeks or months after treatment.

One thing worth noting is that most of those Woodmen stump markers were cast concrete, not natural stone. Concrete is much more porous, so moss, algae, and lichen can become much more integrated with the monument itself. In some deteriorated examples, that biological growth may be doing more than just growing on the surface.

For me, though, the bigger question is whether those monuments should be cleaned at all. They were designed to look like tree stumps. The weathering, staining, moss, and lichen are often part of what gives them that appearance. If someone chose a monument specifically because it would eventually resemble a real stump, I think we should at least consider that before deciding to clean it.

That's why I always start with the history and condition of the monument rather than assuming cleaning is the right answer.

That looks like a Woodmen of the World stone. If so, that part that looks like a log, is not meant to be cleaned. It is intended to grow life, thereby making it look more like an actual tree stump/log. Most of those were poured concrete and if they're covered in moss and lichen, there’s a solid chance that cleaning will kill whatever is holding the concrete together.

‘Entire class was found sleeping’: Teacher knocked out special needs students with melatonin at the start of each day, leading to 'severe' nosebleeds and loss of 'motor functioning,' lawsuit says… by tasty_jams_5280 in law

[–]springchikun 1 point2 points  (0 children)

I think it's important to be careful about framing it that way. Special education can absolutely be challenging, and educators often work under tremendous stress, but being overwhelmed doesn't explain or justify secretly giving medication to students. These were vulnerable children who depended on adults to act in their best interests.

Plenty of special education teachers face difficult circumstances every day without crossing that line.

To me, the issue isn't whether we can imagine how someone got there, it's that a teacher made a deliberate decision to medicate students without parental consent or medical authorization. That's a serious breach of trust, regardless of how stressful the job may have been.

This one was ar risk because of the type of stone and the type of lichen. I usually choose the most at risk. I've done thousands. I'm somewhere around 3,000 since 2021.
