Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. The is usually either an intense red colour (for spherical particles less than 100 nm) or blue/purple (for larger spherical particles or nanorods). Due to their optical, electronic, and molecularrecognition properties, gold nanoparticles are the subject of substantial research, .
· Clean gold thoroughly. The gold surfaces to be joined need to be clean of dirt and grease for the solder to chemically bond them together. Soak them in the pickle solution briefly to remove surface contamination, then rinse in water to remove the acid. Scrub the surfaces with detergent or soap for additional cleaning.
The mesh size of this aluminum powder is 200 vs. the 300 mesh for the other metal powders and gives a better cold cast effect compared with other mesh size powders that we tested. Polished castings are brighter vs. castings made using nickel/silver powder, which has more of an antique metal look.

Commonly used in the jewelry industry is a watertopowder ratio of 40ml of water for every 100gm investment powder. It is simply a ratio of how much of ingredient A to mix with ingredient Bathes gets confused because it can be written in several ways, like 40:100, 40/100, 40, and % of these is trying to convey the same watertopowder ratio.

ATO Lab allows you to quickly produce high quality metal powders. Due to the ordered nature of the atomization process, the output powder has a very narrow particle size distribution, closely depending on the chosen ultrasound frequency. For example for a frequency of 35 kHz, 70% of 316L steel particles are in the diameter range of 40 to 60 µm.
