Not Tempura, tempera. Color things Dark Green or Burnt Sienna (sort of dark brick red) but don't eat these 1-7/8" sq x 3/8" thick, 2 oz cakes of dry paint. From Weber-Costello, they are called "Biggie" and sell for $2.00 in the big boys' catalogs. Don't you love surplus??

3538 MINI-MONSTER PRISM |
Polished glass equilateral prisms. Equilateral because each edge of the end is the same length, 32mm. Thus, as all you geometry students know, each of the angles is also the same, 60 degrees. These are school grade and are fine for decorative and demonstration. They do a nice job of diffracting light to produce a nice rainbow-like spectrum, but are definitely not up to instrumentation standards. The missing dimension, length, is shown below.

A mechanical device used for affixing paper sheets to display boards but which facilitates their easy removal. It has a pointed central metal shaft to pierce the paper and penetrate the display board surface. The paper is held as the shear in the shaft balances the weight of the paper. A green or brown 3/8" dia round metal head on the shaft holds the paper against the board. The devices come (40) to a card and we'll send you (4) cards per order.

Eye dropper, tongue dropper, test tube dropper, petri dish dropper, anywhere dropper. Use this 3" glass dropper, with a rubber squeeze bulb to drop small amounts of liquid wherever you think they should go. You will have to measure by counting drops, though, because there are no markings on it. Also, it is called "3" because that is about how long the glass tube is. Overall, it is 4" long.

Donut magnet you can take to town!! 74mm dia x 14mm thick with a 30mm hole. Very strong and well pedigreed - in fact, its kin are activating pacemakers. They are of a high permeability ferrite material with a lovely light blue or white epoxy coating. Okay, we have them because there is the odd bubble or scratch in the coating which ruled them out of the medical ball, but they're fine company nonetheless. Good display bases, paper clip traps, and super for classroom demos.

Black and white sand in a viscous colored fluid. The sand and fluid are between 5-1/2" wide x 3-1/2" high panes of glass, framed on a gimbaled stand. Flip the panel and watch the sand swirl and eddy into endlessly new pictures of dunes, drifts, mountains or moonscapes, depending on your imagination and the pattern they form. The mix of black and white creates a definite third dimension to the images. They come in assorted colored plastic frames (our choice) and are pretty neat, as these things go.

Maybe a little eclectic for an artist with a single style, but perfect for one who's still searching for himself. Or for any hobbyist. There are no (2) brushes exactly alike in this set of (15). They all have natural bristles, color-coded wooden handles and metal ferrules, but they range from fairly fine to 1/2" wide, and 7" to 10" long. There are at least (3) different kinds of bristles, and they are round, blunt and pointed. A nice variety, and a very nice quality for this price.
