When blended calcines were used, permeabilities were two to three times greater for misted than for unmisted feeds.

By continuance of heat it calcines in white fumes, called argentine flowers of antimony, which melt into a hyacinthine glass.

Guadalupe Creek is impaired (303(d) listed) by mercury contamination. Historically, workers disposed of roasted mercury mining wastes, called calcines, and other waste in or near Guadalupe Creek and Los Alamitos Creek so that waste materials would be transported downstream by winter flows. Guadalupe Reservoir covers a former mercury ore processing area. Calcines and other mining wastes are still present along the banks of Guadalupe Creek above Camden Avenue, along the banks of upper Guadalupe Creek near the former Guadalupe Mine outside of the Almaden Quicksilver County Park.

Worker health in functioning mines is at high risk. The European Union directive calling for compact fluorescent bulbs to be made mandatory by 2012 has encouraged China to re-open cinnabar mines to obtain the mercury required for CFL bulb manufacture. Environmental dangers have been a concern, particularly in the southern cities of Foshan and Guangzhou, and in Guizhou province in the southwest. Abandoned mercury mine processing sites often contain very hazardous waste piles of roasted cinnabar calcines.

The grate preheater consists of a chamber containing a chain-like high-temperature steel moving grate, attached to the cold end of the rotary kiln.Peray op cit, Hewlett op cit, pp 73,74,76 A dry-powder rawmix is turned into a hard pellets of 10–20 mm diameter in a nodulizing pan, with the addition of 10-15% water. The pellets are loaded onto the moving grate, and the hot combustion gases from the rear of the kiln are passed through the bed of pellets from beneath. This dries and partially calcines the rawmix very efficiently.

For example, the National Research Council of Canada routinely publishes such findings.Performance of wood stud shear walls exposed to fire The results are printed as approved designs in the back of the building code. Generally, exposure of drywall on a panel furnace removes the water and calcines the exposed drywall and also heats the studs and fasteners holding the drywall. This typically results in deflection of the assembly towards the fire, as that is the location where the sublimation occurs, which weakens the assembly, due to the fire influence.

In 1998, when first-term Republican State Representative Deborah Tamargo, who had first been elected in a special election the year prior, ran for re-election, Henriquez ran against her in the 58th District. During the campaign, Tamargo sent out controversial campaign literature that asserted that Henriquez could not understand problems like child abuse because he did not have children of his own, to which Henriquez said, "The Lord has not seen fit to bless our marriage with any children yet." " Ultimately, Henriquez defeated Tamargo by a wide margin, winning 56% of the vote to her 44% in one of the few bright spots for the Florida Democratic Party that year. Running for re-election in 2000, he was opposed by Eddy Calcines, a hairdresser and the Republican nominee, and he campaigned on his productivity in the legislature, noting, "Relationships are so important in Tallahassee.
