Means "staining stand" or "color rack" in German, and we think it's some sort of lab gizmo, but in English it translates to a nice, heavy glass dish 8-5/8" x 5-7/8" x 2-1/8", with a 1/4" thick wall. It comes with an adjustable, rectangular metal frame, 6-1/2" to 11" x 2-1/2" x 3-1/8", that fits over it. The dish looks suitable to bake in to us, and carries the Assistent logo. It's certainly a good serving dish, and with a few rubber bands the rack could be a watercolor brush stand/cleaner. Or you could open a German staining lab.

We have a source of reasonably priced borosilicate glass, the kind of glass you can put directly over the flame of a Bunsen burner, or directly onto a hot plate. This glass is imported from China, and is considered student grade, which is good enough for anything but the most exotic applications. Compare the prices below and you will see that they are about half the U.S. equivalent. Call for larger quantity prices.

Great heavy–duty porcelain mortars and pestles. The smaller has a 4–5/16” long pestle, and is 2” high x 4” dia, with sides that are easily 5/16" thick. The larger has a 6–3/4” long pestle, and is 2–7/8” high x 6–3/8” dia, with sides up to 1/2" thick. The mortars are glazed outside, but rough inside, the better to grind, and have a pouring lip. The business ends of the pestles are unglazed, while the shafts are glazed. Very functional, very good looking!

So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 4-3/8 long x 1-1/2" OD neck, a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 7-13/16" tall OA x 4-1/8" dia with a 4" long x 1-3/8" OD neck, 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 3" long x 1-1/8" OD neck, 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job. Style-conscious chemists should note that the neck of the 250ml size fits perfectly into the neck of the 1000ml size to make a terrific minimalist decanter.

So you don't have a gas jet in the garage? You don't think Margie and Ted are old enough to handle the high temperatures of a Bunsen burner? Our alcohol lamps are the answer. They burn alcohol (available at the hardware store), and are hot enough to boil water, to soften glass tubing for bending, and to generate the chemical reactions generally called for in science projects. Lamp (B) is 3-1/8” tall x 2-11/16” square glass with a wick assembly that brings the whole to a height of 4-1/2".
