Fossil ivory or mammoth ivory is sensitive to surrounding temperature and harsh climatic conditions have an adverse impact. Due to its sensitivity to humidity and temperature, when it expands and contracts, it can split due to stress. We ensure that only the purest of ivory is used that is free of any imperfection after being acclimatized for a number of years above ground. To protect your ivory, it is recommended that you rub mineral oil twice a year to replenish its natural oils. Renaissance Wax can be used to give it a protective polished shine.
However, please bear in mind and do not:
Spill or put ink on ivory
Make the ivory wet
Put the ivory in direct sunlight
Let the ivory heat up or freeze
Expose the ivory to fluctuations in temperature and humidity
