This is a newer, much better photo - I was motivated, finally, to replace the old, rather flat, poorly lit one. There are more views here.
MemoryCam ©2006 A brass pinhole camera. 3.5 inches high, 2.25 inches wide. In the tradition of camera manufacturing, the handle is useless. If you lift the camera with it, the bottom falls off and your film is exposed. It's a camera to photograph memories. On the base the instructions read: 1. Fix memory in your mind. 2. Point Memorycam toward memory. 3. Expose film. You can see an earlier stage of the camera and photos taken by it here. More information on my blog.

„Walka żywiołów – ogień i woda”
Gorąca rura niemal natychmiast po opuszczeniu pieca jest intensywnie chłodzona. Celem równomiernego chłodzenia na całym obwodzie rury dysze zraszające są umieszczone z różnych stron i jest ich więcej, dlatego od widocznego na fotografii kolektora wodnego woda doprowadzona jest kilkoma przewodami. Rura chłodzona znajduje się w osłonnym przewodzie rurowym o większej średnicy aby ograniczyć rozprysk wody. Kolejna osłona chroni pancerz pieca przed rozpryskami wody. Rura po całkowitym opuszczeniu stanowiska do hartowania kierowana jest na ruszt odbiorczy do już widocznych w lewym dolnym rogu rur po hartowaniu. Rury te oczekują na kolejny proces czyli odpuszczanie.
„Obróbka cieplna - odpuszczanie”
06.09.2018
Wspomniany wzrost kruchości materiałów stalowych po przeprowadzeniu hartowania powoduje konieczność kolejnego procesu obróbki cieplnej czyli tzw. odpuszczania. Ma ono za zadanie eliminację naprężeń w materiale, powstałych podczas hartowania. Przeprowadzenie odpuszczania skutkuje nieco przeciwnymi do hartowania rezultatami więc mogłoby się wydawać bezzasadne, jednak korzyści płynące z zabiegu (wzrost udarności) są większe niż zmniejszenie wartości wskaźników wytrzymałościowych takich jak twardość. Proces odpuszczania wymaga ponownego nagrzania rury, jednak już do nieco niższych temperatur i bez następnego intensywnego chłodzenia. Piec do odpuszczania jest niemal identyczny jak piec do austenityzacji, jednak pracuje przy niższym zakresie temperatur.
„Obróbka cieplna - hartowanie”
06.09.2018
Najciekawszym w mojej ocenie obszarem produkcyjnym dalszych etapów kształtowania jakości rur jest rejon obróbki cieplnej rur, który powstał podczas trzeciego etapu rozbudowy z lat 1970-1975. Zagadnienie kształtowania jakości wyrobów stalowych na drodze obróbki cieplnej jest niezmiernie szerokie i obejmuje wiele procesów, jednak w przypadku częstochowskiej Walcowi Rur skupia się przede wszystkim na procesach austenityzacji, hartowania i odpuszczania. Jak sama nazwa wskazuje obróbka cieplna wiąże się z wprowadzaniem materiału jej poddawanego do różnych zakresów temperatur, które wpływają na kształtowanie mikrostruktury i tym samym końcowe właściwości wyrobów. Celem osiągnięcia zadanych temperatur konieczne jest eksploatowanie pieców do obróbki cieplnej. Na fotografii piec samotokowo-pokroczny, który nagrzewa rury przed procesem hartowania do temperatur około 850-950˚C w ilości maksymalnie do 24 ton/h. Rury trafiają do pieca przez okno wsadowe na samotokach i po osiągnięciu odpowiedniej temperatury są gotowe do jego opuszczenia. Wysoka temperatura nagrzewania w piecu czyli temperatura austenityzacji skutkuje osiągnięciem struktury austenitycznej stali. Czas nagrzewania jest zależny od gatunku stali oraz grubości ścianki rury i musi pozwolić na osiągnięcie pożądanej temperatury w całej objętości nagrzewanej rury, co skutkuje jednorodną mikrostrukturą. Zbyt krótkie nagrzewanie rury może skutkować niepełnym procesem austenityzacji. Po opuszczeniu pieca w celu przeprowadzenia hartowania rury poddaje się intensywnemu działaniu wody, która jest ośrodkiem chłodzącym o wysokiej efektywności. Szybkość chłodzenia musi zapewnić możliwość uzyskania struktury martenzytycznej. Wyroby stalowe po procesie hartowania mają lepsze właściwości wytrzymałościowe i są twardsze, jednak cechuje je także zwiększona kruchość.

This photo shows the camera open, with a negative on the left. I use light sensitive photo paper as the negative. It is 1.5 x 3.5 inches. It's pretty easy to work with, although the exposures are in minutes. The negative is curved because I cut the paper long and curl it when I put it in the camera. I could cut it to just fit in the back of the camera, but I would not get the image circle. You can see the image circle on the left and right sides of the negative.
Here is a webpage devoted to the camera.

So the brickwork has been done for a few weeks now. But last weekend was cold and rainy so I decided it was time to really finish this project. I brought M. into the lab and set her artistic skills loose on the brick beast. The result is the only Badass High Vacuum Preparation Oven likely in existence.
The full (boring, I'm told) story is blogged here.
I've only taken it to 100 deg. C to feel for heat leaks. On vacation now, but we'll try 450 deg. C next week. Please describe your envy below.
These three 950-silver rings will undergo a heat treatment: 1 hour inside an oven, covered by burned paper, at 200° C. Carbon contained in the burned paper (or charcoal) absorbs oxygen in the surrounding air , diminishing the formation of firestain (black cupric oxide) on the surface of the silver objects. These rings must be completely covered by the burned paper. This procedure raises silver hardness considerably. After this, the rings will be polished. Mauro Cateb, Brazilian jeweler and silversmith.

This machine build in chemnitz in 1927 still working today.
A strip of 950-silver being heated. After this, the strip will be quickly immersed in water (process known as quenching). This procedure softens the metal. Mauro Cateb, Brazilian jeweler and silversmith.

Our Cochin Bantam 'Snowy', model for my home-made, hen-shaped, hot water bottle alternative. Trying to be shopping-free and to make everything ourselves, I had a go at making a 'hot water bottle'. The last commercial one we bought burst and covered me with hot water! This is filled with our chicks' organic grain and made from a remnant of organic percale I had over from making sheets. We heated it in the woodburner at 150C/300F for 15 mins and it was snuggly warm. You can also freeze it in a plastic bag for 3 hours in the freezer and make a cold treatment pad. It’s great for all those aches and sprains you get heaving pallets and perches about in cold weather!

Chauffée comme ici à cuisinière à bois, ou au four traditionnel ou à micro-ondes, la bouillotte Snuggly Snowy aux grains bio vous procure la bien-être et relaxation, décontracte les muscles et apaise les douleurs. Mise au congel (3 heures) Vous pouvez l’utiliser aussi comme compresse froide.
A rough golden-yellow zircon - in white light - before (top image) and after 8h at 950°C (lower image). The before (red line) and after (purple line) 365nm excited fluorescence spectra are shown on a logarithmic flux scale.
The strong yellow fluorescence from radiation-induced colour centres has been removed by heat treatment to reveal prominent lanthanide (REE) fluorescence.
The orange band represents a gaussian profile (in energy, not wavelength, space). We have had some discussion about the meaning of gaussian emission from colour centres.
Heat is an effective method to kill all life stages of bed bugs when temperatures are higher than 122 degrees F. While clothing, bed linens, stuffed animals, and other items can be put directly into the drier, shoes and other items that should not tumble can be placed in a laundry bag that is hung over the door.
