I’m glad that I spent a few days last week preparing the raised garden beds, turning soil, pulling weeds, etc. The last few days have been great weather wise.
Yesterday Blue Jay, Lucy, Pi Guy and I took a bike ride to the Dog Tooth Café. Awesome weather, in the seventies, blue sky.
I also went to Rick’s Garden Center, I found that they carry Burpee seeds, and a flyer sent out recently had a 20% coupon on Burpee seeds. I asked Blue Jay if she wanted to go. If all the spring flowers were out she would have gone. As it was it was just me.
Rick's did have the Starlet Scarlet Marigold that Jael insisted on from A Dyer’s Garden. I also purchased some Basil, Shasta Daisy, Hibiscus, Zinnia, Mammoth Sunflower, some regular Marigold mix, and Red Hot Poker Mix just for fun. I also purchased some peat pots.
I still have some mordant that I need to buy to make our experiments complete. For the tin mordant, was able to locate stannous chloride at B & H Photo. This, also, is a special order for them. I ordered it with the alum, it should take two to four weeks. They have it for about $30 for100 grams. I opted for the 10 gram size (for starters) at $6.
Potassium dichromate for the chrome mordant is a slightly different story. If you happen to be in New York City, B & H Photo has potassium dichromate, but because of the hazard, they don’t ship it. It has it’s own personal “No Fly Zone”. I have some more research to do. I was thinking a metal plating shop. The nearest to me is Denver, about 60 miles distant. But I have located some about 10 miles closer at Colorado Scientific Company. They sell educational materials.
The purchase list for mordants is: ammonium aluminum sulfate and stannous chloride, copper sulfate, and tannic acid from B&H Photo, allowing two to four weeks; Cream of Tarter from Safeway or King Soopers; walnut shells from walnuts also from Safeway or King Soopers. We were fortunate to find copper sulfate for copper mordanting in a home school chemistry set, with the option to replenish our supplies from there. Or, our stand by B & H Photo has it. ~$9/ lb.
Happy fabric treating!

Taking Advantage of a Nice Day
Yesterday was such a gorgeous day, in the low seventies, sunshine, blue sky; I took the kids on a hike over at Palmer Park. (I say this because I’m not going to finish the information on the mordants today, just tannic acid.)
Both Blue Jay and I both forgot cameras, a fact the Blue Jay bewailed repeatedly. There were some excellent views of Pikes Peak and the Front Range, and some awesome sandstone formations on the Templeton Trail.
At the tail end of the hike, which was kind of rugged, we saw bunches of ladybugs on the Yuccas. About three years ago we had hiked in the same area. Blue Jay and pi Guy were intent on counting ladybugs but had no idea that they would be in such abundance. The Yucca plants were like an open square for mobs of them. (Blue Jay corrected me. Mobs are for kangaroos. All is venery.) To see them out on the first day of spring was impressive.
It was a great break. But back to the mordant business, at least for tannic acid to treat the cotton. I just want to be prepared especially if there are lead times to contend with.
I might be able to get tannic acid from a bag of oak leaves or walnut shells brewed up like tea. Walnut shells I can obtain from a metal polisher or metal finishing supplier like Cyclone Sandblasting Equipment (http://www.mytoolstore.com/cyclone/access.html) 50 lbs for ~$55 plus shipping. Lucy’s sister lives near some pecan groves, the owners of which sell shelled pecans. It’s possible that I could obtain some of the waste shells to use like the walnut shells.
We’ll try the brewing of walnut shells and/or pecan shells as an experiment. We could use our own shells obtained from whole walnuts from the grocery store. Or, another plan is to get some sumac and brew that.
If these plans are not successful, I have plan B. Plan B would be to purchase the chemical from our trusty friends at B & H Photo.
Tannin vs. Tannic acid. www.Smarter.com has a lot of coffees and teas listed when looking up tannic acid. However, if you look at an article by Bruce Richardson at Elmwood Inn, Perryville, KY, (http://elmwoodinn.com/about/tannicacid.htm, I like this news letter. I’d like to stay at his Inn someday.) he clearly differentiates between tannins and tannic acid. He even shows the difference in chemical formula, and makes the statement bold, “There is no tannic acid in tea!” So, no tea for tannic acid.
