Bound: You Are the Only, Only, Only by DesignatedGrape

This was the second book I ever bound, but I was relying on the kindness of a friend to deliver it, but it made its way into the hands of its intended recipient (the author, the delightful @designatedgrape, who I followed into the Check, Please fandom as well, so I am very grateful for them) this weekend!

The fic is a Schitt's Creek baseball AU, and I had a lot of fun with that when designing it. I used two different baseball-themed endpapers, and chose a grass green fabric for the cover. The chapter headings featured the corresponding number of baseballs.

My favorite little secret surprise, though, is in the endbands. This was made before I ordered premade endbands, so I had to make them out of fabric. And I found the perfect fabric...

Once you know what the fabric is, you can see it but otherwise they just look like normal endbands.

can you guys chill lmao. just trying to help

Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminium oxide (α-Al2O3) with trace amounts of elements such as iron, titanium, cobalt, lead, chromium, vanadium, magnesium, boron, and silicon. The name sapphire is derived from the Latin word sapphirus, itself from the Greek word sappheiros (σάπφειρος), which referred to lapis lazuli. It is typically blue, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colors; "parti sapphires" show two or more colors. Red corundum stones also occur, but are called rubies rather than sapphires. Pink-colored corundum may be classified either as ruby or sapphire depending on locale. Commonly, natural sapphires are cut and polished into gemstones and worn in jewelry. They also may be created synthetically in laboratories for industrial or decorative purposes in large crystal boules. Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, such as infrared optical components, high-durability windows, wristwatch crystals and movement bearings, and very thin electronic wafers, which are used as the insulating substrates of special-purpose solid-state electronics such as integrated circuits and GaN-based blue LEDs. Sapphire is the birthstone for September and the gem of the 45th anniversary. A sapphire jubilee occurs after 65 years.

Sapphire is one of the two gem-varieties of corundum, the other being ruby (defined as corundum in a shade of red). Although blue is the best-known sapphire color, they occur in other colors, including gray and black, and also can be colorless. A pinkish orange variety of sapphire is called padparadscha.

Significant sapphire deposits are found in Australia, Afghanistan, Cambodia, Cameroon, China (Shandong), Colombia, Ethiopia, India Jammu and Kashmir (Padder, Kishtwar), Kenya, Laos, Madagascar, Malawi, Mozambique, Myanmar (Burma), Nigeria, Rwanda, Sri Lanka, Tanzania, Thailand, United States (Montana) and Vietnam. Sapphire and rubies are often found in the same geographical settings, but they generally have different geological formations. For example, both ruby and sapphire are found in Myanmar's Mogok Stone Tract, but the rubies form in marble, while the sapphire forms in granitic pegmatites or corundum syenites.

Every sapphire mine produces a wide range of quality, and origin is not a guarantee of quality. For sapphire, Jammu and Kashmir receives the highest premium, although Burma, Sri Lanka, and Madagascar also produce large quantities of fine quality gems.

The cost of natural sapphires varies depending on their color, clarity, size, cut, and overall quality. Sapphires that are completely untreated are worth far more than those that have been treated. Geographical origin also has a major impact on price. For most gems of one carat or more, an independent report from a respected laboratory such as GIA, Lotus Gemology, or SSEF, is often required by buyers before they will make a purchase.

Mineral Swag Round 1: Can You Even Tell the Difference?

More information under the cut!

Look, in 2023, natural diamonds are OUT.

I'll be honest, unless you're going to admire the natural shape of a mineral or its raw color and imperfections (for example, garnet in its dodecahedral form), I think natural minerals serve little purpose except education and research! I mean, if you're going to cut up and polish the mineral anyway, why care if it was lab grown (and hundreds of dollars cheaper) or "naturally" formed in the rocks somewhere?

And hopefully most people know by now that natural diamonds are a ethical nightmare! Even conflict free diamonds are not entirely ethical! The prices of diamonds are insanely inflated, many people suffered to get that diamond, and almost no one could tell the difference between a lab-made and natural diamond because they're really the same exact thing.

I suppose I’m not here to rant and rave about natural vs lab-made gems so, onto the specific issue of diamonds vs white sapphires...

There are a couple differences. First off, among lab-created stones, sapphire is usually cheaper.

Of course, diamond will always be harder than sapphire. Jewelry companies say corundum could show more wear than diamond, but unless you're using a piece of jewelry as an industrial grade sandpaper, it's much more likely that the gold jewelry setting will show signs of wear when compared to either gem (gold is very soft) so I'm inclined to say that's mostly a marketing tactic.

But, if you need an industrial grade sandpaper, or a blade for a rock saw, diamond really IS what you need! Diamonds are very efficient when it comes to cutting hard things (including other diamonds) and they absolutely have their place in SCIENCE and maybe in your jewelry, as long as it’s lab-created.

Bonus: Can you tell the difference between these gems, because I'm pretty practiced at comparing rocks and minerals and it’s pretty difficult to tell.

Examples of faceted Al2O3 inclusion in steel

Inclusion name: Alumina Record No.: 1282 Inclusion formula: Al2O3 Inclusion type (Macro/Micro/Nano): Micro Inclusion type (Exogenous/Indigenous): Indigenous Inclusion classification: Oxide Inclusion composition in weight %: No data Sample: Steel Steel composition in weight %: No data Note: Inclusion with well developed facet planes and a three-dimensional character are classified as faceted inclusions (Fig. 1). They are also numerously found in industrial samples. Their size ranges from a few ìm to few tens µm. In the work of Dekkers, faceted inclusions are further classified as octahedral (Fig. 1 (a)) or non-octahedral (Fig. 1 (b)). The reason is the belief that corundum, which cannot develop an octahedral habit, is not the only Al2O3 phase present in liquid steel. Other Al2O3 polymorphs could explain the presence of octahedral inclusions. The facets appear in the crystal habit as a result of slower growth rate, and the subsequent ability of the crystal to arrange the incoming growth units in the configuration that minimises the surface energy. Such growth conditions are obtained at lower supersaturation degree. From that point of view, faceted inclusions cannot be formed during cooling. Also, the size of the polygonal inclusions was found to be independent on the cooling rate of the Fe. As a result of different supersaturation degrees during the growth of the polyhedral crystal, flat, concave or hopper faces (Fig. 1 (c)) on the octahedral inclusions were observed. Large faceted inclusions can also result from the sintering and densification processes of aggregates. Overgrowth of plate-like inclusions or dendrites was occasionally observed on small octahedral inclusions.

Various types of ceramic crucibles: quartz, alumina, boron nitride, zirconia

As an important component of chemical instruments, crucibles are containers for melting and refining metal liquids, as well as solid-liquid heating and reaction. They are the basis for ensuring the smooth progress of chemical reactions. Historically, crucibles were originally made of clay, and one of the earliest uses of platinum was also for preparing crucibles. However, with the development of preparation technology, crucibles can now be made of any material that can melt or change its contents.

There are many types, models, and specifications of crucibles, which can be selected at will, with strong applicability, and can ensure the purity of the smelted material. Among them, ceramic crucibles are an important component of crucibles, and ceramic crucibles can be divided into quartz crucibles, corundum crucibles, boron nitride crucibles, zirconia crucibles, etc. according to the raw materials, and are used in different occasions according to their respective properties.

1. Quartz Ceramic Crucible

Quartz ceramic crucible, full name high-purity fused quartz ceramic crucible (silicon dioxide content ≥ 99.9%), is a ceramic crucible made of high-purity fused quartz as raw material. It has the characteristics of fine structure, low thermal conductivity, small thermal expansion coefficient, good thermal shock stability, good electrical properties, good chemical corrosion resistance, etc. Therefore, quartz ceramic crucible is widely used in the glass deep processing industry, metallurgical industry, electronics industry, chemical industry, aerospace, and other fields. Generally speaking, its shapes are mainly square and cylindrical.

With the attention and development of environmentally friendly energy, solar energy as a green energy has been widely valued by countries around the world. The use of polysilicon for solar energy conversion has increased dramatically, which has promoted the rapid development of polysilicon production. Therefore, the use of large-sized thin-walled square fused quartz ceramic crucibles has also increased dramatically, and the international market prospects are very optimistic about it.

2. Alumina crucible

Corundum crucible, scientific name alumina crucible, people usually call crucibles with an alumina content of more than 95% corundum crucibles. Corundum crucibles are hard and resistant to melting, high-temperature resistance, acid and alkali resistance, rapid cooling, and extreme heat resistance, chemical corrosion resistance, suitable for using anhydrous Na2CO3 and other weak alkaline substances as a flux to melt samples, but not suitable for using Na2O2, NaOH and other strong alkaline substances and acidic substances as a flux to melt samples.

99.70% corundum crucibles have good high-temperature insulation and mechanical strength in an oxidizing and reducing atmosphere of 1650℃-1700℃, and the short-term use temperature can reach up to 1800℃. According to the application conditions, alumina crucibles are available in a variety of sizes and shapes, such as arc crucibles, round bottom crucibles, straight crucibles, square crucibles, etc.

3. Boron nitride crucible

The common types of boron nitride are cubic boron nitride (C-BN) and hexagonal boron nitride (h-BN). Among them, boron nitride crucibles are usually made of h-BN. h-BN ceramics have good heat resistance, thermal stability, thermal conductivity, and high-temperature dielectric strength. They are ideal heat dissipation materials and high-temperature insulation materials.

Due to the excellent chemical stability of h-BN, it can resist the erosion of most molten metals. Because of the above-mentioned high-temperature insulation properties, high thermal conductivity, and low thermal expansion, it is most suitable as a material used in strict environmental conditions such as semiconductor processes. h-BN crucibles are often used for melting metals and semiconductors. Its operating temperature under vacuum is as high as 1800 degrees, and its operating temperature under atmosphere protection can reach up to 2100℃. It is generally protected by nitrogen or argon (atmosphere protection is to prevent the crucible from oxidation).

4. Zirconia crucible

The melting point of zirconia is higher than that of zirconium, reaching 2700℃. It is one of the materials with the best refractory performance in nature. Even if it is heated to 1900℃, it will not react with molten aluminum, iron, nickel, platinum, and other metals, silicates, and acidic slags. Therefore, Zirconia crucibles can successfully melt platinum, palladium, ruthenium, cesium, and other platinum group precious metals and their alloys.

It is worth noting that although zirconia is more expensive than alumina, it is a special oxide refractory material that cannot be replaced by other oxide materials when used in high-temperature furnaces above 2000℃.

Grades Of Emery Cloth

An emery cloth is a fabric coated with abrasive materials of varying grades, each suitable for specific applications. Understanding the different grades of emery cloth is essential to achieve optimal results in your sanding projects. Coarse Grade The coarse grade emery cloth is ideal for heavy-duty sanding tasks, such as removing rust, paint, or corrosion from metal surfaces. It is best suited for initial rough sanding to quickly eliminate imperfections. Medium Grade The medium-grade emery cloth strikes a balance between aggressive sanding and finer finishing. It is suitable for smoothing out rough surfaces, preparing them for a more refined touch, and achieving a moderate level of abrasion. Fine Grade The fine-grade emery cloth is perfect for achieving a smooth and polished finish on metal surfaces. It is great for final touches, removing minor imperfections, and creating a refined surface ready for painting or coating. Which Grade To Use For Specific Applications: - Coarse Grade: Use for heavy-duty tasks like removing rust and corrosion. - Medium Grade: Ideal for smoothing out surfaces before finer finishing. - Fine Grade: Perfect for achieving a polished finish and removing minor imperfections.

How To Use Emery Cloth

Emery cloth is a durable abrasive material with a flexible cloth backing. It is designed for sanding metal surfaces and is ideal for pre-finishing metal surfaces by hand. To use emery cloth, wrap it around a file when finishing metal to achieve a good finish, working through grades from coarse to fine and alternating the direction of the file regularly to remove scratches. Emery cloth is a type of abrasive material that is commonly used for sanding metal surfaces. Unlike traditional sandpaper, it has a durable cloth backing that won't come apart or shred during aggressive sanding, which helps to reduce the possibility of small fragments being left on the prepared surface. To use emery cloth effectively, it's important to follow proper preparation techniques and use the right tools. Preparation for Sanding Before using emery cloth, it's important to prepare the surface to be sanded. This involves cleaning the surface thoroughly to remove any dirt, grease, or other debris that could interfere with the sanding process. Once the surface is clean, it's important to choose the right grade of emery cloth for the job. Coarse grits are best for removing paint, rust, and other stubborn materials, while finer grits are better for smoothing and polishing. Wrapping Emery Cloth around a File When finishing metal by hand, pieces of emery cloth can be wrapped around a file. To do this, simply place the emery cloth on a flat surface with the abrasive side facing up. Place the file on top of the emery cloth and wrap it around the file, making sure to leave enough excess cloth to hold onto while sanding. Alternating the Direction of the File To get a good finish, it's important to work through grades from coarse to fine and regularly alternate the direction of the file to remove scratches by polishing across them. This helps to ensure that the surface is sanded evenly and that all scratches are removed. When using emery cloth, it's important to work slowly and carefully, applying even pressure and taking breaks as needed to avoid overheating the metal. In conclusion, emery cloth is a versatile and durable abrasive material that is ideal for sanding metal surfaces. By following proper preparation techniques and using the right tools, you can achieve a smooth and polished finish that will last for years to come.
