Also, they aren't fun.
I did make an exception to this rule, though, for a friend who wanted an urn for a dog who had passed. He wasn't her dog; he belonged to a friend of hers. I had met Traveler, though, and it is no secret that I have a soft spot for animals.
I agreed to this custom order for a couple of reasons. Barbara is a friend - I 100% would not do this for a stranger or a slight acquaintance. She used to own The Artisan's Barn, a craft gallery in Readfield, and carried my work for several years before she retired, so she is well familiar with the concept of handmade variation; and she was willing to let me make ALL the design decisions - color, shape, handle, all the details. My mission was just "make a nice urn" that would fit the cremains of a 110 pound dog.
I did a bit of math to determine the size: with pet cremains, figure one cubic inch per pound of living weight. The volume of a cylinder is
2 x h
[Pi (3.14 etc)] x [the measurement of the radius, squared (multiplied by itself)] x the height
For ceramics we need to figure in shrinkage; I usually multiply by 1.15 to accommodate 15% shrinkage.
Even so, I made three. One was too small; one was, idk, it was fine but I didn't love it. One was, to quote Goldilocks, just right.
I think of Traveler, sweet boy, and feel glad that I can honor his life in this small way.
