wherein the thermally insulating material can withstand process temperatures of 300° F. or more; and
wherein the thermal energy storage media comprises a metal oxide, non-oxide ceramic, or a metal and has a thermal conductivity of 35 W/m-K or more at 25° C.

2. The thermal transfer blanket of claim 1 , further comprising a thermally transparent layer in direct thermal communication with the thermal energy storage media.

3. The thermal transfer blanket of claim 2 , wherein the thermally transparent layer comprises fiberglass coated with a fluoropolymer.

4. The thermal transfer blanket of claim 1 , further comprising a thermocouple in thermal communication with the thermal energy storage media.

5. The thermal transfer blanket of claim 1 , wherein the thermally insulating material comprises a ceramic batting and a layer of fabric comprising glass that surrounds the ceramic batting.

6. The thermal transfer blanket of claim 1 , wherein the thermally insulating material comprises foam insulation.

7. The thermal transfer blanket of claim 1 , wherein the thermal energy storage media comprises at least one material chosen from AlN, BeO, BN, diamond, Al 2 O 3 , and a metal, and wherein the thermal energy storage media has a specific heat capacity of 300 J/kg·K or more at 25° C.

8. The thermal transfer blanket of claim 7 , wherein thermal energy storage media is pure aluminum.

9. The thermal transfer blanket of claim 1 , wherein the thermal energy storage media comprises one or more layers of tiles, the tiles in each layer being bonded together by an elastomeric polymer.

10. The thermal transfer blanket of claim 9 , wherein the thermal energy storage media comprises 2 to 10 layers of the tiles, the 2 to 10 layers of the tiles comprising at least one layer having tiles of a first length and at least one layer having tiles of a second length that is longer than the first length.

11. The thermal transfer blanket of claim 1 , wherein the thermal energy storage media comprises pellets.

12. The thermal transfer blanket of claim 11 , wherein at least a portion of the pellets are in a matrix material comprising an elastomeric polymer.

13. The thermal transfer blanket of claim 11 , wherein the pellets comprise large pellets and small pellets, the large pellets having interstitial spaces therebetween and the small pellet being sufficiently small to fit in the interstitial spaces between the large pellets.

14. The thermal transfer blanket of claim 11 , wherein the thermal energy storage media further comprises at least one plate comprising metal.

15. The thermal transfer blanket of claim 1 , further comprising a heat storage flap attached to the flexible container.

16. The thermal transfer blanket of claim 15 , wherein the heat storage flap comprises at least one thermal resistive pad.

17. A thermal transfer blanket system, comprising:
a thermal transfer blanket, comprising:
a flexible container comprising a thermally insulating material; and
