Mosaics

Above is a table the Kelly and I made many years ago with glass mosaic tile. We copied a portion of an ancient Roman mosaic depicting sea life. It took about 40 hours of painstaking work.

We still have a box of glass tile sitting in the garage and I’m thinking about breaking up the ugly concrete patio in the back yard and doing some mosaics. Kelly is less than enthused about this for a number of reasons, not least of which is that it will take me away from more pressing matters such as a back door that doesn’t open and a non-functioning computer network.

Nevertheless I was inspired to return to mosaic work after seeing the stunning garden designs of Portland, Oregon based pebble mosaic master Jeffrey Bale.

You can view Bale’s work on his blog and read a great how-to article Bale wrote for Fine Gardening Magazine.

Our squid table was made by gluing the tiles directly to the wood and grouting once all the tiles were in place. This would not work for exterior mosaics. Instead, for my patio I would glue the tiles to a piece of paper and then set them into a mortar mix in place (the indirect method).

Using pebbles as opposed to glass mosaic tile, by the way, cuts costs way down. Should I get permission to do the back patio I’m thinking of combining pebbles with small areas of glass tile. In fact, I may just stop answering emails so that I’ll have the time to do this!

Friday Quiz Answer

The answer to our “Freaky Friday Fungal Quiz”: slime mold. And I should not have used “fungal” in the title. Slime molds are no longer classified as fungi. But I’ll stick with “freaky.” According to UC Berkeley, slime molds fall into three categories,

Plasmodial slime molds, like Physarum . . ., are basically enormous single cells with thousands of nuclei. They are formed when individual flagellated cells swarm together and fuse. The result is one large bag of cytoplasm with many diploid nuclei. These “giant cells” have been extremely useful in studies of cytoplasmic streaming (the movement of cell contents) because it is possible to see this happening even under relatively low magnification. In addition, the large size of the slime mold “cell” makes them easier to manipulate than most cells.

A second group, the cellular slime molds, spend most of their lives as separate single-celled amoeboid protists, but upon the release of a chemical signal, the individual cells aggregate into a great swarm. Cellular slime molds are thus of great interest to cell and developmental biologists, because they provide a comparatively simple and easily manipulated system for understanding how cells interact to generate a multicellular organism. There are two groups of cellular slime molds, the Dictyostelida and the Acrasida, which may not be closely related to each other.

A third group, the Labyrinthulomycota or slime nets, are also called “slime molds”, but appear to be more closely related to the Chromista, and not relatives of the other “slime mold” groups.

Friday Freaky Fungus Quiz

I spotted this strange blobby thing attached to a step just below our porch. Measuring about an inch and a half, it has not changed much in the week since I first noticed it. I suspect that it’s some sort of fungus, but I’m not absolutely sure. I ate about a teaspoon of it and developed an alternative to my usual lecture appearances. Just kidding.

But seriously, what the heck is this thing? LeaveĀ  a comment!

Processing and Winnowing Flax

We grew a five foot circle of flax this winter in the center of our yard. When it came time to harvest said flax I pondered creating the world’s smallest piece of linen. Lacking the time for that process, I opted to simply harvest the seeds.

I used a block of coconut coir to smash the seed heads against a piece of newspaper.

Next came time for winnowing the flax. I used a fan and had to winnow multiple times to get the chaff out.

Alas, there was still quite a bit of chaff. Remembering that I had some 1/8 inch hardware cloth in the garage, I used it to screen out most of the last chaffy bits. You can buy expensive screens for processing seeds, but the amortization on that equipment would take years for our tiny garden.

A huge mess was made. Good thing Kelly is off camping.

In the end I managed to harvest nine ounces of flax seeds. Plans for a flax oil pressing fest were canceled.

Meanwhile, as yet unnamed new kitten ponders the absurdity of the world’s smallest flax seed harvest from her pillow perch.

Pruning and Grafting Workshop with C. Darren Butler

This Sunday May 29, learn how to prune and graft citrus and avocados with consulting arborist, ecological designer, sustainable landscaping specialist, and teacher C. Darren Butler. Slots are still available. It’s a double workshop (pruning in the morning and grafting in the afternoon). You can sign up for one or both. Hope to see some of you there!
