This replacement bottom is from the ANNIVERSARY SERIES and has a glazed finish on the inside. Model # 99140 which is the smallest in the series and holds 3.3 quarts. When you place your order you will received just the base to this Romertopf.
If you have this model but it was made in Mexico by Reco International (see embossed information on the base), then please note this will not fit with your model. This replacement part is only valid for clay roasters which are manufactured in Germany.
