Size L. These tabi are a dark gray with slight variegation, made from a thick, bulky, ultra-cushy yarn.
For some reason I haven't been drawing very much lately. I lost my mojo a bit I think, for a while, but I'm starting to feel the stirrings of desire to draw stuff again. This is a sort of doodly pencil thing I did last night.

The main raw material of carbon graphite crucible is crystalline natural graphite. Therefore, it maintains the original physical and chemical properties of natural graphite. That is: it has good thermal conductivity and high-temperature resistance. In the process of high-temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heating and rapid cooling. It has strong corrosion resistance to acid and alkaline solutions and excellent chemical stability. There are many types and specifications of the graphite casting crucible, which are not limited by the production scale, batch size, and the variety of melting material. It can be selected at will, and has strong applicability, and can ensure the purity of melting material.
Application of Graphite Crucible
Graphite crucible has obvious characteristics and is widely used. The graphite crucible for fire heating is mainly used for smelting copper, aluminum, alloy and other non-ferrous metals. Due to the reasonable design, advanced structure, novel material and low energy consumption compared with the same type of furnace, graphite crucible has been used in many fields, using clean energy such as natural gas or liquefied gas as fuel with less pollution. Resistance furnace high purity graphite crucible is mainly used for melting gold, silver and rare metals.
The graphite crucible has a small coefficient of thermal expansion. It has a strong resistance to strain for both extremely hot and extremely cold. It is resistant to strong acid and alkali, and can be used for heating a variety of liquids; In addition to chemistry, graphite crucible is widely used in metallurgy, casting, machinery, chemical industry and other departments; Graphite crucible is made of natural graphite, which keeps the original excellent characteristics of graphite. It is used to make heating element and heat shield of vacuum furnace, and also used to make structural parts such as bracket, material tray, guide rail, bolt, bearing, fan blade and so on. The application of graphite crucible in vacuum furnace greatly simplifies the design and manufacture of vacuum furnace, reduces the consumption of metals such as tungsten, molybdenum, tantalum and stainless steel, reduces the cost, improves some properties of vacuum furnace and expands the application scope of vacuum furnace.
Graphite Crucible Uses
Put it in a dry place after use, and avoid rainwater intrusion; Bake slowly to 500 ℃ before use.
According to the capacity of the carbon graphite crucible, do not squeeze too tightly, so as to avoid the metal thermal expansion cracking the crucible.
When taking out the molten metal, scoop it out with a spoon, and useless calipers as far as possible. If calipers and other tools are used, they should be consistent with the shape of the crucible, so as to avoid local excessive stress and shorten the service life.
The service life of the graphite casting crucible is related to its usage. It should be avoided that the strong oxidation flame is sprayed directly on the crucible, which shortens the service life of the raw material.
During the boat ride in Bhedghat you will come across various scenic view points and some rare rock stones. Here you can see the raw form of graphite stone.
Graphite. I forgot the door!! It was two in the morning, after slaving over this all night, and after taking a break and returning, I noticed the photograph and drawing were a 'bit' different. Yup! No door!! Oh no!!!!!! I had to redo the entire piece in just a few hours and that was one loooong night of drawing!! Enjoy the laughs!!
This was where the term 'persistence of vision' was probably coined :)

woohoo! i didn't cave in for the neverfull damier, although i wanted it so much. i kept telling myself, save it, stop it! you're going to get the ricoh...it's much more worthier than this...accckkk!!!
This is a pencil sketch that I did as a study for a children's book illustration job that I am working on. I love the asymmetrical-ness of it. It makes me think of the quirky habits of little boys. Its a universal phenomenon!

Graphite block, as the name suggests, refers to block graphite. It is a kind of artificial graphite, which is made of coke products by artificial heating and other processes. Because of its structure, carbon graphite block has the following properties: high-temperature resistance, conductivity, thermal conductivity, lubricity, chemical stability, plasticity and thermal shock resistance.
Graphite Blocks for Sale
High Purity Graphite Block
High purity graphite block, also known as molded graphite, means that the carbon content of graphite is>99.99%, which has excellent characteristics such as good conductivity, thermal conductivity, oxidation resistance, low resistance coefficient, high purity, self-lubricating, thermal shock resistance, isotropy, and easy processing. It is widely used in aerospace, solar photovoltaic and semiconductor, continuous casting, cemented carbide and electronic mold sintering, EDM, glass, machinery, energy, and other industries.
Electrolytic Graphite Block
The anode of electrolytic graphite electrolysis often oxidizes the anions in the solution into simple substances or other high valence states.
Graphite Block For Vacuum Furnace
The application of Graphite Block For Vacuum Furnace in vacuum furnaces greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, and stainless steel, reduces the cost, improves some properties of vacuum furnace and expands the application range of vacuum furnace.
Application of graphite block in metallurgy and casting production
Graphite block is an industrial graphite product obtained by deep processing of graphite electrodes! Here is a brief introduction to the application and precautions of graphite block in powder metallurgy and metal casting:
The use of graphite block in powder metallurgy is mainly in the sintering link. The raw materials are put on the graphite block and melted different metals through high temperatures in the sintering furnace or vacuum furnace. Due to the high-temperature resistance and oxidation resistance of graphite block itself, it can meet the requirements of the powder metallurgy industry. Graphite welding block can be used repeatedly, which can save economic costs for customers!
Let's talk about the use of carbon graphite blocks in the foundry industry. The metal can be heated in a graphite crucible to 1500 ℃ and become liquid. At this time, the graphite mold casting method can be used to cast the required industrial products. Graphite mold casting is simply that graphite mold casting is similar to metal mold casting. It has good thermal conductivity and thermochemical stability. Casting tin bronze and aluminum iron bronze with graphite mold can overcome the casting defects such as shrinkage, porosity, and pinhole, and improve the mechanical properties.

Limestone is often blackish on the outside, but whitish within.... this stuff is black all the way through due to the presence of graphite. Probably Ordovician age. From Upper Takaka, Nelson.
