Frost dragon bones are obtained from killing a Frost dragon. When buried, they give 180 Prayer experience each. This can be increased to 630 experience using a Gilded Altar in a player owned house with both burners lit, 720 when used with the Ectofuntus and even to 945 when using a Gilded Altar in a player owned house with both burners lit while wearing Brawling gloves (prayer) and 1001.7 exp if you have Clan Avatar 6% xp boost with you. Frost dragon bones are the best tradeable bones in the game and the second best bones in the game (after the Ancient Bones which give 200 experience each), giving 2.5 times the experience of dragon bones and 28.6% more experience than Ourg bones.
Without a familiar, players can gain approximately 575,000 Prayer experience per hour using frost dragon bones on a gilded altar with both burners lit. Using a Pack yak can bring the rate up to approximately 1 million experience per hour. At this rate, players can get from 0 to 200 million experience in about 200 hours of playtime, for the cost of around 3,059,047,619 coins.
Frost dragon bones can be obtained by non-members from Frost Dragons in Daemonheim; they are members-only items outside Daemonheim. When used on an altar inside of Daemonheim, players receive 720 experience.
This table can be used to compare and decide on how to train with the bones for the most desired cost versus experience gained. Notice how the cost in coins per XP point varies greatly depending on how the bones are used — but also remember that the different methods have different training speeds.
The costs only include the cost of bones. The cost of clean marrentills used with the burners is not calculated.
Trivia

Shortly before Bot Nuke Day some players predicted that most highly Bot obtained items would increase in price, this caused many to get rich quickly off rising prices. Frost dragon bones quickly rose in price after the "nuke" was launched, from around 10,000 gp all the way up to 19,706 gp within a month. They began to slowly decrease in price as bots slowly returned.
The examine text of these bones is a joke on the examine text of dragon bones, "These would feed a dog for months."
