Inventions

Retaining her memories from her past life as Urano, Myne has recreated a number of items, dishes, and other products from her old world, mostly for her own comfort. Many are based on what she learned from her previous mother.

Claiming that Tuuli would be cuter with a "hair ornament", Myne used the lace tatting technique to make flowers out of thread. The flowers are then sewed together by their ends and attached to a wooden pin.

A thin wooden stick made from whittling wood. Myne asks Tuuli for a stick similar to Tuuli's doll's legs to tie up her hair, which she makes for Myne.

Flash cards with letters on them. They are designed to help kids identify letters and learn to read. The game mechanics follow the same rules as the karuta from earth which centers around the hundred poems. Myne's karuta cards have a drawn illustration and the starting letter from the object drawn written on them. The objects are focusing on topics of the bible.

Wax candles with herbs on them, acting as a deodorant compared to the normally smelly candles. How to make: Removing waste by boiling oil over a gentle fire and adding saltwater. When the oil on the top hardens, pour out the saltwater at the bottom to get clean oil. This process is called salting out.

Simple All-in-One Shampoo, later renamed to Rinsham by Benno for marketing reasons, is made with meryl oil (or other vegetable oil), herbs for aroma, salt, and hot water to dissolve the salt. The simple all-in-one shampoo turns out to be valuable, as it makes the hair smooth and shiny, and the effects especially draw the attention of women.

Upon Rozemyne's entry into noble society Rinsham becomes very popular among even the highest ranking nobles of Ehrenfest.

Spoiler from Part 4 Volume 2 Over the course of several years Benno establishes workshops dedicated to the production of Rinsham, not just in Ehrenfest, but with the help of his younger sister and other more distant family members in cities throughout Ehrenfest.

Following the picture books, Myne begins creating and printing children's bibles. Each book has its own god as topic. She simplifies the bible's language and adds a few illustrations.

Used to sort books into an order in a library. There are 10 categories and several sub-categories to classify the books into. It is based on the Nippon Decimal System.

When Myne found out she was going to be a big sister, she decided to make a picture book for the baby. It has pictures containing simple forms like squares and triangles arranged in certain manners.

By having Ingo, Johann and Zack cooperate, Rozemyne is able to create various versions of printing presses - machines that can very easily create multiple copies of the same texts in a very short timespan. They started out by modifying a food press as a proof-of-concept and a stepping stone, but have since developed purpose-built printing presses that are expected to revolutionize the world.

Rozemyne got inspiration for these machines from Earth's Johannes Gutenberg, who also started his pioneering of the printing technology by modifying a wine-press.

In Myne's new world it is common to discard the broth after the vegetables have been overcooked, leading to a flavourless soup. Myne introduces tasty soup by making people use the water they cooked their vegetables in before.

Salting out is used to reduce the stench and create higher quality oil for candles etc. Salt is put into the cooking water and left simmering while removing emerging impurities.

In the beginning Myne was unable to do math using a calculator. She uses her slate and solves problems using the methods taught on earth. Mark is intrigued and learned a bit from Myne.

Inspired by the Mesopotamian civilization, Myne shaped clay into tablets to write records on them. However, like the imitation papyrus attempt, it failed, the first time due to Fey and his friends stepping on them, the second time due to the gate closing, the third time due to a rainstorm, and the fourth time due to failure to bake them in the kiln.

Papyrus is made from the fibers of a stalk and weaved like a piece of cloth. Myne tried making paper imitating papyrus as her winter handiwork, but she gave up.

Mokkan from the Huang civilization, are pieces of wooden slips. Originally, Myne planned to write on them with ink, but she didn't have any ink, so she used soot mixed with water as a substitute, but that was a failure. Effa used her first mokkans as firewood later, resulting in Myne getting frustrated and collapsing.

There are several different types of paper that Myne and Lutz make. They all use wood from trees. It's a production requires several days in which and requires steaming, soaking and beating the wood, before it is mixed with other ingrediants, filtered and eventually dried.

Spoiler from Part 4 Volume 2 Once Rozemyne starts to show off plant-paper at the Royal Academy she switches to calling it "new paper" to hide any insight into the production method for as long as possible, to maximize the profit Ehrenfest can make from it. After a discussion with her trusted merchants the decision is made to call name the plant paper after the provinces it is produced in. Volrin and Trombe paper thus become "Ehrenfest Paper" and trauperle paper is called "Illgner Paper".

Since the regular ink used for parchament is too acidic and damages plant paper over longer periods of time, as well as the high cost of buying the quantities of ink required for printing, Myne had to invent her own ink. This ink is made by mixing finely crushed soot with oil.

Later she tasked the Bierce Workshop with developing coloured ink. The people doing the actual research within the workshop were Heidi and Josef, who Myne granted the title of Gutenberg upon the successful completion of the task.

When coloured plant-paper ink is applied onto plant paper or mixed with other colours, the colours change in counter-intuitive and seemingly random ways. The ink also quickly loses intensity, leaving only faded letters behind. This can be prevented by treating the paper with a fixing agent before applying the coloured ink. This was able to figure this out thanks to her mother's expertise with dyes.

Wax Paper is made by coating a piece of paper with very thin layers of wax in a specialized machine. Once the wax is cooled down, this wax paper can be used to create stenzil templates that work better and last much longer than those made from regular paper. It can also be used to prevent the surfaces on which the printing takes place from getting ink on them. The thinner the paper used for this the better.

The only paper that can be made thin enough to be suitable for this process is trombe paper, since any other kind of paper the Rozemyne Workshop tried to thin down became impossible to peel off of the drying stand without ripping.

Spoiler from Part 4 Volume 3 Recently Illgner managed to produce the equally thin rinfin paper, which is sure to reduce the cost of wax paper, since trombe paper is the highest priced premium paper due to it's quality.

Chopsticks are made of bamboo and used for paper making. They are equivalent to chopsticks from earth.

Myne asks her father Gunther to make a stick with a hook end out of wood so that she could make Tuuli's hair ornament.

Myne found the clothing hangers in her new world unpractical (which they really are) and suggests the form she knows from earth to Benno. They are made out of metal.

The diptych is the equivalent to a notepad. It is made of two wooden carved-in boards connected with metal rings on one side. The boards are hand-sized and filled with wax inside them to note down things using a stylus.

The stylus a piece of metal formed like a pen which has a pointed end on one end and a flat-shaped on the other end. The pointed end is used to write on the diptych's wax whereas the flat end is used to erase the writing. It comes with a hook, resemling earth's pens, so that it can be attached to the metal rings of the diptych.

Handpump are devices that can be installed at wells to enable easier access to water. By using a vaccum within the device, you can get water to flow out of the nozzle simply by pumping the lever, which requires far less time and strength than using a rope or chain to pull a full bucket from from the bottom of the well.

Hide glue is made of a really sticky paste harvested from the skin and bones from animals. It is used to harden book covers and for making a certain ink. Glue made from skin had a higher water resistance than glue made from bones. Both glues are made by creating a mixture containing limewater.

The precision knife is a small and narrow blade used to cut paper. The handle is made out of wood and the exchangable blade is made of metal. Myne requests the blade to be fit perfectly into the handle to ensure safety.

The roller is made of metal and used to spread ink evenly.

The first stencil templates Myne and Lutz used were made from tick paper. Later Rozemyne used wax paper to make stencils that were thinner and re-usable.
