Princeton Catalyst, Series 6400, Long-Handle Synthetic Polytip B


Product Description

Catalyst professional art brushes are yet another breakthrough that advances the science of synthetic hair. The fine craftsmen at Princeton created a new series of brushes that offer the stiffness and responsiveness you need, even in water. Catalyst brushes have real integrity in water, unlike natural hog bristles, which can be rendered useless when water-soaked. The true advance in these painting brushes is the Polytip bristles. For the first time, the tip of each individual hair has been split to replicate the natural flags found on the finest natural bristle. By giving each individual hair two to three distinct tips, Catalyst is able to hold a higher volume of paint while providing amazing detail and a smoother application. Designed for use with medium to heavy-bodied acrylic and oil paints, Catalyst paint brushes even push heavy gel media. Catalyst Polytip Bristle brushes truly are tools that move paint.

Mountain and polar groups at the twenty-sixth United Nations Climate Change Conference of the Parties (COP26) are calling for more consideration of the dire global impacts that will result should governments not take greater action as the climate talks in Glasgow begin their second and final week.

22 September 2021

Arctic sea ice has likely reached its minimum extent for the year, at 4.72 million square kilometers (1.82 million square miles) on September 16, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 minimum is the twelfth lowest in the nearly 43-year satellite record. The last 15 years are the lowest 15 sea ice extents in the satellite record. 

14 September 2021

Each September, the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder informs the public of the annual Arctic sea ice minimum extent, an indicator of how climate change is affecting the Arctic, the fastest-warming region of the globe.

Scientists at Northern Arizona University, Arizona State University, the Arizona Geological Survey at the University of Arizona, and the National Snow and Ice Data Center at the University of Colorado Boulder have been awarded almost $2 million from the National Science Foundation (NSF) to develop a virtual reality teaching tool called Polar Explorer.

The National Snow and Ice Data Center (NSIDC) announced this week their participation in the 50x30 Coalition, a group of governments and cryosphere and emissions research institutions endorsing the need to reduce greenhouse gas emissions 50 percent by 2030. The Coalition’s founding members endorse the scientific consensus that failure to reach this milestone will result in temperature “overshoot,” in which emissions remain too high to hold Earth within 1.5 degrees Celsius of pre-industrial levels, leading to major and irreversible damages to the environment. Damage may be especially harmful for highly temperature-sensitive frozen components of the Earth system, with impacts ranging from sea level rise to infrastructure damage to food insecurity.
