Can demi glace be made in a slow cooker?

Every recipe of demi glace I come across is reduced for a long time above a small open flame and since I don’t want to burn down my house I’d prefer making it in a slowcooker. Will it work if I just follow the normal recipe and do the 18 hours of reducing in the slowcooker or should I make any other adjustments? submitted by /u/PrintingPariah
