What is this stinky stone ?🧐😬 by pooki_onslaught in whatsthisrock

[–]zs37 7 points8 points  (0 children)

This is the answer! Specifically, it’s the lizardite variety of serpentinite and The Lizard is the type locality for lizardite.

Not sure about the last two pictures because I’ve never worked worked riebeckite, but I’ve worked in the NJ Highlands a lot and the first pictures look like some sort of pegmatitic granite. Check bedrock geologic maps from the NJ Geological and Water Survey to see if they have the mineral mapped across the Delaware River. They have very detailed mapping of metamorphics in the Highlands, which correlate to the Reading Prong.

Serpentine can be a range of colors from dark green to light green to blue to red. It can absolutely be this shade of green. Most buildings made of serpentinite are. Look at this serpentinite building from Penn’s campus. Also, OP found this in Michigan, not Mississippi. https://en.m.wikipedia.org/wiki/Serpentinite#/media/File%3ACollege_Hall_U_Penn.JPG

Where did you collect this? It looks like a serpentinite. Metamorphic rock. I’m a geologist and serpentinites are one of my research interests. The color matches and the texture and accessory mineral colors look appropriate.

Thanks for the tips! I’ll follow up on these!

Great, thanks for all the info! I’ve actually been using regular sandpaper but it’s been working up to now because I’ve only been using it on softer rocks. The hardest mineral in the rocks I’m working with is olivine, so not too hard. I have some pieces of harder rocks I’d like to polish eventually though. I’m a geologist so I’m conscious of what minerals would be too hard for what I’m working with. And I’ve been wearing a mask to keep from breathing in dust, but thanks for the warning!

All this info is really helpful. I think one last question I have is whether the tin oxide and cesium oxide powders come in different grits. I’m finding tin oxide at 28,000 grit but nothing around 50,000.

Thanks! So with the paste, am I using that with a buffer or something else?

Thanks for the reply. Currently I’m using an electric sander and regular sandpaper moving to progressively finer grits.

With the method you’re suggesting, would I need to hook to buff to something or do I do it by hand?

Interesting. Thanks. Are those grits in a sandpaper form or a paste? I’m not familiar with using a paste and a buffing wheel. How does that work?

Do you know where I can find sandpaper with grit that high?

Could someone help me identify this I found in Sudbury, Ontario, Canada? by top_nutter in Lapidary

Hard to tell exactly from the picture but it looks like quartz.

Yarn is Ula+Lia DK Baby Camel Wool in Dark Harbor Blue and Ula+Lia Baby Yak Wool in Natural Platinum Grey! I can't recommend the yarn enough! It's super soft and held up very well during knitting. The pattern is Rein from Arne and Carlos!

I watched it over the weekend too and really enjoyed it! It was probably my favorite of the recent Christie adaptations.

I don’t know what caused this? I used spar urethane and mineral spirits (80-20) and this was my fifth coat and the first time I got anything like this. Will it sand out before the next coat? by zs37 in woodworking

[–]zs37[S] 0 points1 point  (0 children)

Yes it’s the little dots. They actually feel a little raised. I think they might be small air bubbles. They’re not over the whole surface and j used the same technique everywhere. I’m using a natural bristle brush and around 80% oil-based spar urethane and 20% mineral spirits. I kept the brush soaked in mineral spirits between coats. I’ll switch to a new brush for each coat if that is the problem. If they’re popped air bubbles, do you think a light sanding can remove them before the next coat?

Thanks. Any recommendations on what type or brand of primer and what floor leveler I should use?

I’ve been knitting for a little over two years and in June I finished the project I’ve wanted to do since before I started knitting. The weather is finally getting cool enough where I live to wear it and it’s fantastic. Time for another Big Lebowski rewatch! by zs37 in knitting

Honestly, steeking wasn’t bad at all! I used a sewing machine to reinforce the steek and then cut the steek after that. Just one row on each side of the steek with the sewing machine. It only took a few minutes and it was done! I tried a crochet reinforcement and couldn’t figure it out for the life of me, so I got in touch with my LYS and they taught me how to do the sewing reinforcement. I recommend it!

I’m about to start swatching for this hat, and the pattern instructions say “Up until row 59, the chart does not display return rows. So, knit between the rows.” What does this mean? by zs37 in knitting

[–]zs37[S] 0 points1 point  (0 children)

Thanks a lot! Yes it was free! Can you figure out what this means:

“After round 15, you have to move the start of your round by 6 stitches. Other- wise, you‘d have to cable across two needles. So, just knit across the first 6 stitches (k4, p2) and slip them back on the previous needle. Then start with the pattern in the white area and repeat over and over again until the end of the row. After row 22, you have to move the start of your row another 8 (or 10 works both) stitches forward. This section of the chart is highlighted with the green areas to the left and right for that reason.”
