Dunno what it was originally for. But I bet it could find some interesting uses.
Great score.

A purchase of 6 quartz tubes to try some thermoacoustic experiments or with
ornamental feathers, indigenous ceremonial peace pipes of some sort. 17 mm OD X 43 cm length to the elbow.
A simple experiment some months ago with mixed results.

Not having anything in mind but since they were for a dozen quartz tubes I offered the small amount of $25 and won the bid. They were new old stock,
10 of the taller ones and 2 shorter that were still in sealed decaying plastic bags in an old partitioned cardboard box. They are Leco combustion
tubes or as another eBay seller describes them a "172MM*35MM high frequency infrared carbon and sulfur analyzer quartz tube". There're several sellers
and it looks like the going price for a same/similar non-brand is around $45.00 a tube.
An "enthralling" video of how they are loaded into this machine.

And a free gift which I don't know as of yet what I would use it for.

I thought I was buying a fused quartz dish 150mm x 140mm diameter, thick 5mm wall petri dish because I couldn't see the photos very well on eBay,
occluded by the glare and somewhat opaque bags it came in.
"Was $149.99 (75% off) $37.50 or Best Offer" I won bidding $32 and the $21.00 shipping cost.
DESCRIPTION
"GM 150mm and 140mm Fused Quartz Round Flat Bottom Lab Dish"
"This lab dish is specifically designed to meet the needs of medical and laboratory professionals. With a fused quartz material, it provides a durable
and reliable surface for a variety of applications. Measuring 150mm and 140mm in diameter, it offers ample space for mixing and holding samples."
"The dish is manufactured by GM and features the model number 551-031400-1. Its round, flat bottom design ensures stability and prevents spills. Ideal
for a range of medical and lab procedures, this dish is a must-have for any professional in the field."
The package arrived with two dishes, one sort of resting partially in the other. The bottoms are a heavy 10mm thick, the larger 150mm diameter dish
with a 68mm high wall. Together the two weigh a little over 1 kilogram. Now to find a good use for them.

I bought some of these casserole dishes because they seem to be fairly good for handling heat. The intention was to try to use them to make a hot air
jumper.

Here's one of the fused quartz lab dishes bought previously.
