Appendix A: Tables

Table A.1: The other Galactic Bulge PNe observed with Spitzer/IRS (program $\char93$ 3633).

Table A.2: The rest of PNe (non-Galactic Bulge) observed within Spitzer/IRS program $\char93$ 3633.

Figure B.1:

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry (see Table 1). The spectral type is shown under name of PN. Note the simultaneous detection of PAH emission features in the 6-14 $\mu$ m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m - left panels).

Figure B.2:

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry cont. (see Table 1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Note the simultaneous detection of PAH emission features in the 6-14 $\mu$ m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m - left panels).

Figure B.4:

Spitzer/IRS spectra of Galactic Bulge PNe, which do not show dual-dust chemistry (see Table A.1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m on the left panels mark position of crystalline silicate bands, while those at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m on the right panels show position of PAH features.

The spectral type is shown under name of PN. Dashed vertical lines at 23.5, 27.5 and 33.8 $\mu$ m on the left panels mark position of crystalline silicate bands, while those at 6.2, ``7.7'', 8.6 and 11.3 $\mu$ m on the right panels show position of PAH features.
