1,500-Year-Old Christian Ivory Reliquary Box Discovered in Austria

Archaeologists have discovered an exceptional Christian ancient ivory reliquary box in Austria that is thought to be around 1,500 years old.

Innsbruck archaeologists have been excavating in an old hilltop settlement in southern Austria since the summer of 2016. They made the incredible discovery of a Christian reliquary concealed in a previously unknown church two years ago. This reliquary contained an ancient ivory box, richly decorated with Christian symbols.

The incredible artifact was discovered on August 4, 2022, in an early Christian church on the Burgbichl hill in Irschen, southern Austria, by a team headed by archaeologist Gerald Grabherr. A marble shrine measuring around 20 by 30 centimeters was hidden under the altar in the side chapel area.

The artifact in question is heavily fragmented, but researchers said the pieces once formed a type of round container known as a “pyx” that in this case was made of ivory and richly decorated with Christian motifs.

The shrine contained a heavily fragmented ivory “box” (pyx) richly decorated with Christian motifs – a reliquary that is normally taken away as the “holiest” part when a church is abandoned. In this case, however, it was left behind. It is the first such pyx to be found in an archaeological context in Austria.

“We know of around 40 ivory boxes of this kind worldwide and, as far as I know, the last time one of these was found during excavations was around 100 years ago – the few pyxes that exist are either preserved in cathedral treasures or exhibited in museums,” explains the finder, Gerald Grabherr.

While the archaeologists initially assumed that the remains of a saint – i.e. a relic in the classic sense of the word – were also found in the marble box, the layering of the fragments found in the shrine indicates that the ivory pyx was already broken in late antiquity and was buried in the altar.

“The pyx was presumably also seen as sacred and was treated as such because it was in contact with a relic. The archaeological and art-historical significance of the pyx cannot be denied,” emphasizes Gerald Grabherr.

At one end, the pyx shows a figure at the foot of a mountain – the man depicted is turning his gaze away and a hand rising out of the sky above him, placing something between the person’s arms.

“This is the typical depiction of the handing over of the laws to Moses on Mount Sinai, the beginning of the covenant between God and man from the Old Testament,” says Gerald Grabherr. This is followed by depictions of biblical figures. At the end, you can see a man on a chariot with two horses harnessed to it – and here, too, a hand coming out of the clouds pulls this figure up into heaven. “We assume that this is a depiction of the ascension of Christ, the fulfilment of the covenant with God. The depiction of scenes from the Old Testament and their connection with scenes from the New Testament New Testament is typical of late antiquity and thus fits in with our pyx; however, the depiction of the Ascension of Christ with a so-called biga, a two-horse chariot, is very special and previously unknown.”

Since its discovery, the 1,500-year-old ivory pyx has been conserved at the University of Innsbruck.

Ivory stored underground absorbs moisture, making it very soft and easily damaged. Uncontrolled drying can lead to shrinkage and cracks.

Ulrike Töchterle, head of the restoration workshop in Innsbruck, said, “The high humidity in the marble shrine meant there was a high risk of condensation and mold, so we had to ensure a careful and prolonged drying process.”

Over the past two years, the individual pieces of the ivory pyx have been conserved for scientific analysis. The larger parts are deformed, so the pyx cannot be restored to its original state. However, researchers are working on a 3D reconstruction.

The oldest use of fired clay we've found are figurines like the the Venus of Dolni Věstonice, which is about 31,000-27,000 years old. It was about 20,000 years ago that pottery took on the shape of a vessel in East Asia, from the area of present day China and Japan, which were joined by a land bridge at the time. They were simple objects, purely utilitarian, and some had scorching that indicate they were used for cooking. This was during the Late Glacial Maximum, when people were still living in mobile hunting and gathering groups, before the advent of settled agriculture

In Western Asia, stone like alabaster and calcite were used until about 9000 years ago (about 7000 BCE), especially around the upper Euphrates, in modern day Syria. Once settled agriculture was adopted, pottery began to be made, starting with coiling ropes of clay that were then smoothed before the vessel was fired. The decorations on pottery were very localized, as were the styles, so much so that archaeologists name pre-writing cultures by their pottery. Early pottery was fired in bonfires, possibly by accident at first, which could reach temperatures of 900 °C (1,650 °F). Because clay was used without any tempering in it at first, the vessels made had rounded bases to prevent cracking. Gradually, with the addition of sand, crushed shell or pottery, or grit, the shrinkage of clay while it was drying was better controlled, allowing for flatter bottoms and more creative shaping methods.

In about 4000 BCE (6000 years ago), the potter's wheel was developed in eastern Europe, along with higher temperature kilns that could fire pottery at 1050-1200 °C (1920-2190 °F), making a broader array of pottery shapes possible. Potters began to be a separate occupation, which allowed more artistic freedom such that items like cooking utensils and rat traps were made from pottery. Glazing also became much easier with the higher temperature kilns.

The ancient Greeks developed elaborately painted pottery showing scenes from mythology, life, and heroic exploits, most often with black against the red clay figures. Though glazing was possible, it wasn't often used by them, instead using a slip type clay as decoration. The Romans changed the focus from painted decoration to applied shapes in a newly (about 600 BCE) discovered molding process. Their pottery was typically made in areas like Germany or France in industrial scale, rather than in Rome itself, and was imported. Though pottery was widely and abundantly produced, it wasn't used as tableware by the Greeks and Romans, instead being used for storage and decoration.

In contrast, Chinese pottery began using glazing around 1500 BCE, though the elite preferred plain colored pottery that was elegantly formed. The elite also used pottery for tableware and for religious purposes. Porcelain began to appear during the Tang dynasty (618-906 CE), but didn't gain its now well-known blue and white decorations until the Yuan dynasty (1271-1368 CE).

Pottery was independently developed in the Americas as it didn't appear until about 9500 years ago (7500 BCE) in Brazil being the earliest known pottery. In Mesoamerica, pottery began to appear in the Archaic Era (from 3500-2000 BCE), which included finely decorated pottery but not glazing, stoneware, or porcelain, but did include terracotta and sculptures as well as vessels. As in the Old World, each civilization developed particular styles and decorations for their pottery.

Still working on my Frank pin. 💚 I’m doing gravity pewter casting in a silicone mold and as you can see, even after a double-digit number of attempts I still haven’t figured out the correct amount of pewter to pour while also trying to account for the shrinkage happening in the middle. Tremor is not helping either (lol) but it’s going a lot better than I expected!

Pin design is based on nostalgebraist-autoresponder’s avatar, which is itself an edited version of the painting Horse in Analogous Color Scheme by doni19.

[0m3g4skanohiforge]

Just realized I hit a proper milestone a while back and never celebrated - a successful version of what my very first attempt was, a Red Komau

The first attempt was messy. Filled with tiny bubbles, a big hole in the forehead, mouth lacking definition, soft, and transparent/inaccurate colour. It hardly fits in the mouth properly, the original mold did not get those precise shapes accurately. Nowadays, while my Komau mold isn't 100% perfect and current resin has ever-so-slight shrinkage, I've got a good match for Red and the shape is near-indistinguishable without careful examination or tools.

As with any art form, it's easy to see others doing it and think it must be easy. But by far, the most important thing is dedication and perseverance. (Second most important is safety!) I wanna thank everyone in this community for all their kind words while I developed the skills and experience needed to produce casts like this.

[anonymusbosch]

it's cool to have my parts come in and test them out and see the phenomena from my injection molding textbook play out in front of me. look at that! it breaks right at that stress concentration! or when overloaded here, it breaks right at the weld line! there's shrinkage here and here! even stuff like anisotropic strength due to the orientation of the glass fibers and the polymer strands is right there in front of my eyes. yes!! yes!!

When Is The Investment Casting Employed?

A wax pattern is used in the industrial process of Investment casting China, sometimes referred to as precision casting or lost-wax casting, to create a disposable ceramic mold. The exact shape of the object to be cast is captured in a wax pattern. A ceramic substance that is refractory is applied to this design. After the ceramic material solidifies, it is heated and flipped upside down until the wax melts and runs out. The ceramic shell hardens into a disposable investment mold. The mold is filled with molten metal, which is then allowed to cool. After that, the metal casting is broken out of the used mold.

When to employ investment casting

Investment casting is a rather expensive technique because of its labor needs and intricacy, but the advantages frequently exceed the drawbacks. Almost any metal may be cast for an investment. 

Excellent as-cast surface finishes may be achieved in complicated items produced by investment casting. Since the ceramic shells of investment castings break away from the part when it cools, a taper does not need to be incorporated to extract the components from their molds. With the use of this manufacturing feature, castings with 90-degree angles may be created without any shrinkage allowance and without the need for further machining to achieve such angles.

Parts made using the investment casting technique by Investment casting Supplier have excellent dimensional precision, are readily net-shaped, and are frequently produced without the need for further machining. To create wax patterns, a new die is needed for every distinct casting run. 

The time and effort saved by reducing or eliminating secondary machining more than offsets the expense of new tools for high-volume orders. Lesser casting runs will probably not pay for itself. 

A new wax pattern to a finished casting typically takes seven days, most of which is spent making and curing the ceramic shell mold. To make castings more rapid, certain foundries can quick-dry. Cost is not the only factor affected by investment casting's time- and labor-intensive process. Longer lead times for the investment casting process are typical at foundries because of their restricted production capacity and equipment.

Making clay handles for a saw.

*I wanted to make ceramic handles for a saw that has been hanging on the wall at the back of my house for years now.

*I took the idea from Artist Richard Slee who did a full exhibition on Futile Utilities.

The tricky part of this is making the handles that can fit on over the saw and look like it's part of it.

I got a lot of help from Elaine, with ideas and teaching how to actually cut a straight edge in clay, how to hold a knife and score, score then cut.

I hope that with the shrinkage in the kiln, the handles will fit🤞

I also did some porcelain clay on my ready made mold.

It was a bit sticky taking it off so Elaine guided me, once again through the process, trying two different types of porcelain paper clay

[the-bjd-community-confess]

A bit of info for collectors: sometimes when companies/artists refuse to re-release an old model it’s not because they don’t want to, but because they just can’t. Molds have a set amount of casts they can produce and if the master head is lost, all they could do is recast one of their own heads, which leads to a new set of issues including but not limited to shrinkage and loss of detail. It may be also that they just want to move forward to different sculpts.

Well my pressure pot works!

It's outputting some nice bubble free dice

I gotta make new molds though. I didn't cure my molds in the pressure pot and so i got all these little beads on the surface and the wells for shrinkage weren't big enough

I'm so close to being able to make dice good enough to sell though!

am i the only one who's like. really bothered by the popularity of resin crafts in the past few years.

Like, I've seen maybe one person on youtube EVER address the fact that Absolutely Anything You Make With Resin Will Turn Yellow In 2 Years (And Probably Crack).

It depends on the type of resin, how fast it goes and how yellow it gets, but ALL resin will turn eventually. Like, there's a reason why most snowglobes are made from glass or injection-molded plastic! There's a reason why the tried-and-true pre-DIY processes for producing these things ARE tried-and-true. Because they LAST. Resin just doesn't. Within a few years, your snowglobe or shaker charm will be yellow and it may even crack and leak.

What bothers me the most about resin crafting is the people "preserving" things in it. People starting businesses preserving keepsakes in resin.

It breaks my heart to know that people are handing off their wedding bouquets to be coated in resin, thinking they'll be beautiful forever. But then in a couple years, it'll be ugly and yellow. Nobody tells them this.

I literally have 2 bottles on my desk of resin base and hardener that I bought in 2020, with the intent of using it to make a costume piece (I never did.) The hardener is piss-yellow now and appears to have shrunk somehow (the bottle is dented as if there's negative pressure inside). That will happen to anything you make with it. And that shrinkage will cause cracks and weaken connections if you've used it to glue pieces together.
