Product Information

IMPORTANT- do NOTlet the glass get too hot while buffing - the glass should get warm to the touch for best results but not too hot - control excessive temperature by spraying with water and keep the buffing pad moving continuously. Cerium oxide, or cerium dioxide, is the most often cream-colored powder (it can also be white or slightly pink). It is used not only to remove scratches on glass, but also to clean marble, terracotta and stones. It is most often used for windows polishing, car and motorcycle windows, mirrors, headlights, car mirrors and other glass surfaces. Manual polishing of glass with cerium oxide is both simple and effective, and is gaining more and more favorable opinions. All because cerium dioxide is a delicate substance that removes scratches and other damage and gives shine, leaving no streaks or damaging the glass. Cerium oxide - DIY glass polisher If the scratch can be felt with a fingernail, it is probably too deep to remove by polishing alone. You will need to grind out the scratch with progressively finer grit. This is a more specialised (and tedious!) job and it may be best to seek the advice of professionals in these cases. Cerium oxide is a rare earth oxide that is commonly used in smelting metallic cerium and additives for various materials. It began being used in 1940 as a substitute for iron oxide in glass polishing and has since become an indispensable part of this process. The main advantages of rare earth polishing powder, which has a high cerium oxide content, over the traditional iron oxide is its faster polishing speed, higher smoothness, and longer service life. By utilizing cerium oxide during polishing, the processing time for a lens can be reduced from 30 to 60 minutes to only one minute. Choosing the right grit size is important for optimal results. Grit refers to the size of the particles in the polishing compound. This is measured in microns (μm).

NB:Keep the surface wet to prevent glass getting hot - if sufficient polish has already been applied, then just spray a fine mist of water to keep the area cool. Inspect regularly. Smartphones are really easy to use thanks to their large touchscreens that dominate the entire front of the handset. The downside is that a scratch on the front can be incredibly annoying, and can often create a rainbow effect on everything that you view. Preparation: The glass surface is cleaned thoroughly to remove any dust, dirt, or contaminants. It's essential to start with a clean surface to avoid scratching the glass during the polishing process. Then, in 2010, I bought some TXP and #61 Rapid Polish from Val Carver. The TXP produced a fantastic polish on all of my tumbled stones. The #61 Rapid Polish did a great job on my cabochons and flat surface polishing. So, I stopped using cerium oxide because of its much higher cost. I am now happy with TXP and #61 Rapid Polish almost every time I use them. Toughened glass offers some protection, but even this isn’t enough to completely protect your handset and you can easily get scratches.

Cerium oxide is an all-purpose lapidary polish that can be used on wheels and flat laps covered with leather, felt, canvas, or other popular coverings. A slurry of cerium oxide and water is applied to the wheel or lap and kept wet during the polish by spritzing with water from a spray bottle. For harder materials like turquoise, add more polish. You can use up to four tablespoons of cerium oxide powder per pound of material with good results. a marking crayon or masking tape to mark the inside of the glass (use this to guide you when polishing) In a rotary tumbler, most materials will tumble to a bright polish with cerium oxide in about seven days. The exception is materials with a Mohs hardness greater than seven, such as topaz, beryl, or tourmaline, which might require an extra two days or more to attain a fully developed polish. Certified Mobile Repair Specialist Expert Interview. 10 February 2022. Cellphones have never been so fragile and prone to scratching as they are today. Screen protectors are commonplace, and you should invest in one if you're the slightest bit worried about damaging your phone. Common phone protectors aren't generally too expensive, and they'll be much more affordable than replacing your screen or phone if the damage is bad enough. Higher-end protectors are virtually unbreakable, while affordable brands will at least take damage so your phone proper won't have to.

For valuable pieces, please seek professional advice before attempting a DIY repair. Aussie Sapphire will not be responsible for damage caused by untrained users. For final polishing, opt for 1 micron or 0.3 micron grit cerium oxide. The smaller the particles, the higher the polish.

My Experience With Cerium Oxide

Two main types of domestic producers of cerium oxide polishing powder are recognized. The first is rare earth mining and processing enterprises that produce cerium oxide as a by-product. The process involves ball milling and sieving, resulting in particles of various sizes. Representative of such enterprises are those in Inner Mongolia and Jiangxi. These products can only be used on low-end glass products after mixing with water. The second type of companies specialize solely in the production of cerium oxide polishing powder, perfecting its particle size distribution and designs specifically for certain sectors. Some companies will even purify cerium oxide, but very few have the technology needed to control the micro powder’s morphology and crystal form. Exploring the Advancements of Cerium Oxide Slurry Gao Q (2016) Polishing characteristics of fixed-abrasive pad by using nano-aggregate silica. Opt Precis Eng 24(10):2490–2497 Slurry or Paste: A mixture of cerium oxide powder and a suitable carrier liquid, often water, is prepared. The cerium oxide particles are dispersed evenly in the liquid to form a slurry or paste with a specific consistency. Pure cerium oxide polish is usually white in color. As the purity declines the color departs from white - often to yellow, then to orangy or pinkish. Most quality tumbling roughs that have been run through a fine grit step (500 or 600 grit silicon carbide) are ready for polishing. When we use cerium polish in a tumbler, we go straight from the fine grit step to polishing.

There are some alternatives for cerium oxide powder that can be used in place of regular polishing compounds.However, some people like to run an extra-fine grit step (1000 mesh silicon carbide) before polishing. This might improve the luster of your tumbled stones, or reduce polishing time, but it is possible to get great results without this extra-fine grit step. Polishing stones and gems to a beautiful, jewelry-quality shine is an artform perfected by lapidarists over centuries. While methods and tools have evolved, one essential material remains a staple for achieving flawless results – cerium oxide. This versatile polishing compound can transform rough, dull stones into dazzling gemstones with the right techniques. Savio G, Meneghello R, Concheri G (2009) A surface roughness predictive model in deterministic polishing of ground glass moulds. Int J Mach Tools Manuf 49(1):1–7 Next, close your tumbler lid tightly before putting on a rubber band around it so that it will not come off during use. Cerium is not corrosive, but it does not take much to rust metal.

Cerium Oxide compounds polish glass by a combination of mechanical and chemical action. The material must reach and maintain a certain temperature to stimulate the chemical reaction. The mechanical action employs felt pads or wheels. For surface restoration, the Cerium Oxide is mixed with water to form a thin paste that is applied directly to the glass surface. A damp felt pad or wheel is then used to agitate the paste. The friction of the wheel creates the heat needed to activate the polishing process. Too much heat will dry the paste, so care must be taken to keep the paste wet at all times. Cerium oxide micropowder plays a key role in the cerium oxide grinding fluid, and its quality directly affects the grinding effect of the grinding fluid. The factors that affect the quality of cerium oxide micro powder mainly include the particle size and distribution of the micro powder, the microscopic morphology and aggregation state of the micro powder, and the crystal structure of the micro powder. Cerium oxide is not as aggressive as aluminum oxide or silicon carbide, so it will not damage softer stones as those other polishes will.QUANTITY REQUIRED:we sell cerium oxide in quantities ranging from 100 grams up to 25 kilograms. If you have just a small scratch in an isolated area, then 100 grams will be sufficient. For a bit bigger job such as a car windscreen, we would suggest 250 grams. For larger areas, then you will need more but it really depends on the particular job. Rouge powder leaves behind much fewer scratches than sandpaper but takes longer so isn’t usually recommended unless you have a lot of time on your hands! Hello there and good afternoon to you too! Congratulations on completing your first tumbling, that’s great news! It’s common to have stones lose their shine once they’re dry, but don’t worry, there are a few things you can do to get them glossy again.
