Why Aren't My Cremains White?
Cremains come in various colors from the crematorium, from chalk white to charcoal black. The color of the cremains is usually a function of the temperature the crematorium was run at and the percentage of material other than Tri-Calcium Phosphate (what 'pure' cremains consists of) is left once the cremation process is over.
If you happen to have cremains that are particularly dark we can still work with them, however your Spirit Pieces may have more bubbling than lighter colored cremains as the remaining organic matter turns to gas. For products made by hot glass this may mean the cremains will be harder to see, but they will usually turn white from the process. For lampwork products (animal figurines, touchstones) the darker colored cremains will make the final piece darker than it would be otherwise.
