My oven is arriving tomorrow I forgot to order a blade fixture can I use some ceramic tiles?
 
I band-sawed some notches in a piece of angle iron. Used it that way for over a year, till the angle finally de-carbed/oxidized to pieces.
 
I don't see why you couldn't use ceramic tiles. Like Jason, I had made a quick fixture out of left over scrap steel. Three pieces, two shorter pieces have three notches cut in them in a row, the other longer piece has one notch on each end. I place the end notch of the longer piece in the middle notch of each shorter piece. This gives a fixture that will hold two blades at once. Didn't even bother welding it together, just disassemble when not in use. I like Jason's idea better, just place the angle iron down like an upside down V, and cut a few notches in the top. That one piece should hold the blade(s) well....if not use two.
 
i made a little table(4" square) out of perforated stainless with stainless machine screws. has worked for over a year. a place to check would be a pottery supply house if there is one near by. one of my heat treat furnaces was a front load pottery kiln in a previous life and came with some "kiln furniture" that works ok. the angle iron idea sounds good too
 
Don't discount the EvenHeat Blade racks. I've used inverted angle iron - slotted firebricks - ceramic stands with tungsten pins..... All had problems of decarb / scale, cracked bricks, hot pieces falling on the floor when you try to take a blade out.. Nothing matches the simple efficacy of the Evenheat racks.
 
A lot depends on how many blades per week you'll be heat treating - like myself, 3 or 4 per month, a piece of Stainless bar with a 90º bend in one end works just fine. I expect it to last well in excess of a year. If HT'ing several blades per week, then I'd go with the Evenheat fixtures for sure.

I have some plain tile without any glaze with some grooves cut in it that works great and I think I have two bucks investedIMAG0341.jpg
 
I cut slots in fire bricks with a masonry blade in a Skil saw. Raises the blade edges closer to my thermal sensor, and holds heat for faster recovery after opening then closing the door.
